Among the current selection of soft contacts, the Acuvue Oasys family of lenses is taking their place in the ‘neighborhood’ and is rapidly growing in popularity. They have stepped to the forefront, becoming a leading brand prescribed by eye doctors.
Acuvue Oasys, Acuvue Oasys for Astigmatism, and Acuvue Oasys for Presbyopia all share features that contribute to the ongoing improvement in comfort and extended wear desired by contact users.
The trademarked Hydraclear Plus technology approximates the way eyes naturally stay wet, with a delivery of moisture that lasts all day even in environments and conditions that rapidly produce dryness. The use of senofilcon A (a silicone hydrogel material) facilitates a high flow of oxygen through the lens--a necessary process to maintain eye health. This unbeatable combination gets you as close to that feeling of ‘not wearing any contacts at all’ as any soft lens can.
The Acuvue Oasys family has also forged ahead in the area of UV protection, blocking 96% of UV-A radiation and 99% of UV-B radiation from reaching the covered portion of the eye*. These numbers put Acuvue Oasys at the top of the list in this regard, gaining seals of acceptance for ultraviolet absorbing contact lenses from both the American Optometric Association and the World Council of Optometry.
In addition to the comfort and UV protection, Acuvue Oasys for Astigmatism delivers constant, crisp vision due to its four-point Accelerated Stabilization Design that keeps the lens from rotating (and causing a loss of focus). Acuvue Oasys for Presbyopia employs Stereo Precision Technology to achieve clear sight at all distances.
Many contact users who are introduced to the Acuvue Oasys family are happy with the results, and there are others who are switching from their prior contacts to get this same satisfaction. One such individual, age 60, has spent much of her forty-four ‘contact years’ settling for just three hours of comfortable lens wear a day. After recently discovering Acuvue Oasys, she now experiences several days of wear without discomfort. Another turned away from ‘old’ Acuvue Oasys after an initial trial only to come back and embrace the improved brand.
Acuvue Oasys is FDA approved for two-week daily wear or six nights of extended wear. Ask your eye doctor about the Acuvue Oasys family member best suited for you.
*All other areas of the eye still need to be protected from ultraviolet radiation. These lenses are no substitute for UV-protecting eyewear such as sunglasses, goggles, etc.
UV-A radiation damages collagen fibers (which support cell structure) and destroys Vitamin A in the skin.
UV-B radiation does direct DNA damage that leads to skin cancer.

O2 Optix Contact Lenses
The news is out. Contact lens wearers with busy, daylong activities can now enjoy finding new freedom and confidence with O2 Optix.
In the past, insufficient oxygen flow to the eyes--related to materials in the manufacture of many contact lenses--caused redness, irritation, and dryness before the day was done. Any enjoyment of lengthy activities was marred by having to switch out of contacts and/or wear glasses.
Recently, all that has changed thanks to the introduction of silicone hydrogels. These innovative materials have allowed contact lenses to be made with an amazing improvement in the rate of oxygen flow to the eyes. Among these lenses is Ciba Vision’s O2 Optix, rapidly becoming popular among soft contact wearers who have been looking for that safe ‘all-day’ lens.
Prescribed for the correction of myopia (nearsightedness) and hyperopia (farsightedness), O2 Optix is designed to provide the highest levels of moisture and oxygen permeability possible with a soft contact lens. Also, the surface of the O2 Optix is specially treated to resist protein and other deposits naturally produced by the eye or come from handling the lens. All this technology helps to minimize common symptoms associated with Corneal Oxygen Deficiency, e.g., irritation, blurred vision, dryness and redness. Since these complaints can shorten contact wear-time, the revolutionary features of O2 Optix are a welcome contribution to ongoing eye health for those wearing their lenses for longer periods during the day.
All-day activities become easier and can be enjoyed fully without having to remove contacts because of ‘tired’ eyes and dryness. So go ahead with that hike or excursion, the healthy and fresh feeling you have with O2 Optix will continue for hours.
Other features of the O2 Optix are the blue tint and tiny ‘Ciba Vision’ lettering applied to the lenses, as an assist in seeing the contacts better within solution (or if they’re dropped or lost and you need to retrieve them) and in orientation before insertion.
Satisfied wearers describe O2 Optix as “desirable”, “(of) high quality”, and “an easy choice”. They also suffer less from ‘eye fatigue’ and see their eyes maintain a ‘healthy whiteness’. As the popularity of these lenses grows, many patients are asking eye care professionals about them.
O2 Optix, a 1-2 week disposable lens, is FDA approved for daily and extended wear up to six nights.
As always, consult your eye doctor in determining what the best lens and care regimen is for you.

Convincing Your Parents About Contacts
You are a teen (or pre-teen) with a vision problem that needs correction, but the thought of having to wear glasses turns you off. You would love to be able to wear contacts, but your parents may not think it’s a good idea. How do you convince them otherwise?
First, make sure your motivations for having contacts are practical. Peer pressure should not be an overriding factor in your decision. The argument “but all my friends wear them” is not a winning one in this case. Yes, contact lenses are ‘cool’, they make you look more attractive, and you won’t be called ‘four-eyes’, but more importantly they also allow you to better participate in sports and other activities, tend to bolster your self-esteem and give you more confidence in social interactions. Contact lenses also eliminate the obstruction to peripheral (or side) vision caused by eyeglass frames and make it less awkward when having to don sport or safety goggles. Improvements in technology and manufacture have made lenses more convenient and comfortable.
The major concern of parents is that their children may be too young for contacts. For many years, the prevailing notion was that the constant changes in kids’ eyes as they matured excluded them from wearing contact lenses until adulthood. This idea has been disproved in recent studies conducted with children ranging from 17 down to as young as eight being successfully fitted with contacts*. So now, ‘too young’ becomes less a matter about age and more about responsibility.
In this regard, you are dealing with the perception that young people are somewhat irresponsible, especially in cases where follow-through and continued diligence are necessary. The fact is people are able to assume responsibility at different ages, and this is to your advantage if you have shown mature behavior in the past. It is best to remember that contacts are medical devices, so you must be prepared to have more frequent visits with your eye doctor. Beyond initial fitting and instruction on how to insert and remove your contacts, there are appointments to monitor changes in your prescription and prevent possible problems concerning eye health. Obviously, your doctor’s instructions must be obeyed faithfully. Depending on what type of contact you wear, there are regimens for care and cleaning that are to be strictly followed. If you successfully prove your ability to make these adjustments, obtaining contacts will become much easier.

Contact Lens Cases
Contact lens wearers have always focused on the selection and fitting of their contact lenses. However, with the exception of perhaps selecting a ‘nifty’ color, less attention is paid by many to the lens case in which their contacts will be stored. This is an oversight that could lead to serious eye-health problems.
Currently, a large portion of research in the contact lens field centers on preventing and treating infections that result from contaminated lenses. The condition of contact lens cases must also be considered a factor; especially when a recent study* discovered that nearly one quarter of cases in use are never replaced. This is extremely alarming because when not properly cared for or discarded, these cases become reservoirs for dangerous bacteria that threaten the health of the wearer’s eyes. The implications are more serious when realizing that an increasing number of children are being fitted for contacts. If parents are lax in lens care, it is logical to assume that this behavior will be passed onto their kids.
One very serious condition that can stem from unclean contact lens cases is acanthamoeba keratitis. This is a microbial infection that in its advanced stages leads to ulceration of the cornea and the need for a corneal transplant. Symptoms include irritation, sensitivity to light, tearing, and the feeling that something is in the eye. At times diagnosis is not immediate, as these symptoms mirror other types of eye infections.
Whether it is due to neglect or lack of awareness, the negative trend in lens case care must be reversed. Nearly 80% of complications related to contact use are due to patients not applying proper care techniques. The important thing to remember is that contacts are not just fashionable accessories, but regulated medical devices that require the utmost diligence (and that includes cases) to safeguard your eyes.
Recommended contact lens case replacement is once a month, and during the time a case is kept the following steps should be taken:
· Always wash hands before handling contact lens or the lens case.
· Never use tap water (which may contain bacteria) to clean lens cases. Use a solution and air-dry with the lids open.
· Never ‘top-off’ old solution with new. Use fresh solution each time you store the lenses.
· Do not allow solution bottle tips to touch any surface, including your body, as this leads to contamination.
· Do not use solutions past their expiration date.
Also available are case-holders that keep track of replacement times for both lenses and cases. These are handy for those who do not want to rely on their memory alone.
Consult your eye care professional about contact lens and lens case care, types of solutions that are best suited for your needs, and any changes in care regimen that you plan to make. Be sure to follow all your doctor’s instructions.

Air Optix Night and Day Aqua
Are you a contact lens wearer with a busy schedule? Then you surely must have experienced the occasional need to take a time out from your hectic day for a refreshing catnap. The only thing is, you probably didn’t think of removing your contacts—and you awoke still wearing them. Forgetting your contacts in your eyes while sleeping may be acceptable from time to time, however potential eye-health problems could occur if occasional forgetfulness becomes neglect. Wouldn’t it be great if there were a contact lens with a wearing regimen that could accommodate your style of living?
Now there is.
More on-the-go people are looking for a contact lens that is compatible with their lifestyle: full and active with little time or patience for life’s inconveniences (such as time out for frequent lens care). Many find the answer with Air Optix Night & Day Aqua, a monthly disposable that has been approved by the FDA for up to 30 nights of continuous wear. *
If this contact sounds familiar, it is because recently Ciba Vision changed the brand name of its Focus Night & Day to Air Optix Night & Day Aqua. Many active contact wearers quickly realize the benefits of this new brand, a soft lens with an emphasis on comfort. Air Optix Night & Day Aqua offers the same fit as Focus Night & Day, with the addition of Ciba’s ‘Aqua Moisture System’. This silicone hydrogel innovation delivers six times more oxygen through the lens than the prior brand, achieving a continual ‘breathability’ that contributes to healthy eyes. They are also moister, with a surface that reduces build-up of deposits—a combination dramatically lowering the rate of dehydration and discomfort that may occur at the end of the day. The result is a contact that can be worn while sleeping; which, aside from convenience, gives one the advantage of waking up to crisp, clear vision.
Those satisfied with Air Optix Night & Day Aqua enthuse about the natural feeling they get with their use, which increases due to not having to ‘bother’ with them for an extended period. Also, reduction in ‘red-eye’ or irritation, as well as the fresh sensation stemming from the oxygen flow through the lens adds to their comfort. Impromptu naps can take place without concern for failing to remove them.
If you are a busy mom, frequent business traveler, involved student, or just want a few less hassles in your life, then Air Optix Night & Day Aqua may be the contact lens for you.
* To minimize risks that may come with continuous wear contacts, be sure to strictly follow your eye-care professional’s instructions.

PureVision Multi-Focals
If you are one of the increasing number of individuals being diagnosed with presbyopia and are overly concerned about it, don’t be.
You are not alone. Onset presbyopia (difficulty focusing up close) is occurring to more people as the segment of the population 35 years of age and older grows. Within the next decade, that segment will increase by an additional 16 million. Changes in lifestyles, both at work and home, have made more demands on our near vision. Computer screens, I-phones, and PDAs, etc., keep our eyes busy many hours a day and is contributing to the population experiencing presbyopia earlier than previous generations.
Despite what one may think, contact lens users do not have to give in to the wearing of half eyes, bifocals, or reading glasses. The good news is that they can continue enjoying the benefits of contacts by switching to multi-focals. Even though multi-focal lenses exist, eye care professionals state only 2 out of 5 presbyopic patients realize they are available—or that these lenses can correct their condition. Multi-focals work similarly to progressive eyeglasses, as they have a range of powers in each lens. One’s visual system learns to choose the proper power depending on how close or distant the focus. As it turns out in most cases, this adaptation occurs without difficulty—making multi-focals a viable alternative to monovision (a contact lens application where one eye is corrected for distance and the other for near vision).
Eye care professionals, seeing increasing satisfaction with fittings, are being encouraged to make patients aware of PureVision Multi-Focals, lenses which are among the leaders in correcting presbyopia. They allow wearers to focus at all distances, providing clear intermediate vision with easy transition to far and near. Active individuals hindered by glasses can now go from reading a book to using the computer or taking a drive with a renewed sense of freedom.
Comfort has been enhanced in the PureVision Multi-Focals by the lens’ silicone hydrogel construction, in this case the trademarked AerGel material, which minimizes the buildup of dust, debris and proteins that can collect on the lens. They also stay moist and allow proper oxygen permeability, promoting healthy eyes. An innovative rounded-edge design contributes to the feeling of not wearing any contact lens at all.
Over 80% of multi-focal contact users state these lenses do not cause any interference or disruption in their lives. PureVision Multi-Focals also do much to preserve youthful appearance and confidence.
PureVision Multi-Focals have been approved for daily wear, or continuous wear up to thirty days. As always, consult your eye care professional in determining what is best suited for you.

Don’t Panic Over Presbyopia
Presbyopia is the condition of having blurry near vision when trying to read or perform other close work, such as using the computer. Characterized by the wearing of half eyes, it has been stereotyped as something that happens to ‘old people’ and is lumped into the same imagery as canes, shawls, rocking chairs and sensible shoes. So, it is not surprising that many who are first diagnosed with presbyopia go into a mini-panic, thinking that social security checks and nursing homes are just around the corner.
Well, that is not necessarily the case.
The onset of presbyopia takes place around the age of 35-40 and despite what some might say, that is not old. In a world where we see more people reaching their 90s and remaining spirited and active for many of those later years, the onset of presbyopia seems to be coming on at a relatively young age. In this light, typing the condition as an ‘old people’s affliction’ doesn’t seem to fit.
No one escapes presbyopia because it occurs naturally as eyes age. The natural lenses of the eyes thicken, as we grow older, become more opaque as the protein that forms their building blocks becomes older and less transparent from the center outward. All of this causes less flexibility, less clarity and the decreasing ability to focus on close objects.
Common corrections for presbyopes include the aforementioned half eyes, bifocals and progressive addition eyeglasses. The latter have no ‘dividing lines’ in the lenses, allowing for a smoother focusing transition from distance to near sight. Some patients are satisfied to have a pair of glasses for near vision and another for distance—switching them as needs demand. Also prescribed at times are half eyes in combination with contact lenses powered for distance.
Emerging Presbyopes, who were contact-wearers before being diagnosed, ask if this means they are stuck with having to wear glasses. Fortunately for the 92% who wish to remain in contacts, technology in the past few years has allowed the manufacture of bifocal and multi-focal lenses that treat presbyopia. Another application is monovision, the technique of fitting one’s dominant eye for distance vision and the other for near vision. However, this is viable only for those who can adapt to the dissimilar prescriptions and wouldn’t be bothered by a lack of depth perception that results.
Overall, the contact lens option is certainly desirable for those who want to continue the youthful freedom and natural feel that contacts give without being reminded of ‘advancing age’ by the use of eyeglasses.
Hopefully, armed with the above information, having to deal with presbyopia should be less panic inducing. Taking everything into consideration, it becomes just another treatable eye condition that happens as we go about the business of living our lives.
Well, that is not necessarily the case.

Fortunately for the 92% who wish to remain in contacts, technology in the past few years has allowed the manufacture of bifocal and multi-focal lenses that treat presbyopia. Another application is monovision, the technique of fitting one’s dominant eye for distance vision and the other for near vision. However, this is viable only for those who can adapt to the dissimilar prescriptions and wouldn’t be bothered by a lack of depth perception that results.
Overall, the contact lens option is certainly desirable for those who want to continue the youthful freedom and natural feel that contacts give without being reminded of ‘advancing age’ by the use of eyeglasses.
Hopefully, armed with the above information, having to deal with presbyopia should be less panic inducing. Taking everything into consideration, it becomes just another treatable eye condition that happens as we go about the business of living our lives.

Contacts vs. LASIK
Have you considered LASIK surgery to correct your vision only to find out you are not a good candidate for the procedure? Does the whole idea of elective surgery on your eyes give you pause? Let’s look at the viable contact lens alternative.
Why consider contacts when one of the reasons for having LASIK performed is to become free of lenses or eyeglasses? Because, in some cases, even successful LASIK recipients later need to be prescribed eyewear for the onset of presbyopia, the loss of near-focusing ability often associated with aging. Also, the time it takes for the corrected vision achieved by the laser procedure to stabilize can be somewhere between three and six months; and that vision is slightly less than perfect 90 % of the time for those with extreme prescriptions, falling within a range of 20/20 to 20/40. In these instances, a further procedure—known as enhancement—is called for. Unfortunately, there are some patients that cannot have this additional treatment if their cornea is too thin or other factors evolve resulting from the initial surgery. Contacts tend to give crisper vision and more immediate satisfaction at less risk.
Just as LASIK has advanced in the past decade, so have contacts. Some optometrists express amazement at how the field has progressed. New types of lenses, manufactured with materials that have improved comfort and convenience are prevalent. The introduction of silicone hydrogels, which allow more oxygen to permeate to the cornea, has extended contact wear time in some instances up to thirty days. For those who are able to tolerate overnight wear, these contacts approximate the same non-hassle ‘freedom’ that LASIK would give. It should be noted that proper care and commitment to a prescribed replacement regimen is still vital to avoid eye problems associated with lens use. As a contrast to extended or continual wear, daily disposables have seen a surge in favor among patients who like the handiness of just using their lenses once and discarding them at the end of the day.
LASIK can correct myopia (nearsightedness), hyperopia (farsightedness), and astigmatism (fuzzy vision due to an asymmetrical cornea). There is also a procedure for the aforementioned presbyopia. It involves the principle of monovision, where one eye (usually the dominant one) is corrected for distance vision and the other for near vision. Patients’ adaptability plays a large part in the success of monovision and many must be prepared for a loss in depth perception. Contacts are available to treat presbyopia in addition to all the above-listed conditions. For presbyopia there are lenses manufactured using a bifocal or a multi-focal design or one can also use regular lenses specifically fitted in monovision. As with LASIK recipients, monovision contact-wearers have the same concerns regarding adaptability and depth perception. Multi-focals provide a full depth of field, with a gradual transition between near and far powers in the same lens.
Other considerations in choosing contact lenses include not having to worry about aggravated dry-eyes, which can occur with LASIK, necessitating ongoing medication to facilitate tear production. With the laser procedure there is also the possibility that employment may be affected (some jobs prohibit employees who have undergone refractive surgery). Though uncommon, reports of postoperative symptoms that do not go away (double vision, heightened sensitivity to light, and vision loss due to dramatic corneal reshaping) exist. Night driving vision performance has been diminished in a number of LASIK patients--especially those with myopia--due to glare, ‘starbursts’ and halos seen around lights.
So, the benefits of contact lens wear as an alternative to LASIK are well worth weighing. Of course any final decision can only be determined, as always, after a thorough discussion with your eye care professional.

Kids and Contacts
When it comes to children wearing contact lenses, there are certain questions that arise. Among them: At what age can children begin wearing contacts safely? When do they become responsible enough to accept and handle the regimen necessary for maintaining their lenses?
According to the Contact Lenses In Pediatrics (CLIP)* study, children as young as eight can be successfully introduced to contact lens wear. Colleges of optometry in Ohio, Massachusetts, and Texas jointly conducted the study. Their findings refute the prevailing opinion that children should not be offered the option of wearing contacts until 13 years of age.
One part of the CLIP study was to fit a group of 84 children, beginning at age 8, with contact lenses and provide the proper training for insertion and removal. They were re-examined at points one-week, one-month, and three-months from the initial visit to assess their progress and check for any problems. With only three non-serious incidents reported (and quickly corrected), the children demonstrated their ability to wear and take care of their lenses at the same level as teens and adults.
Of course, proper motivation was important in keeping the kids on a successful track throughout the duration of the study (and, hopefully, beyond). Besides the eye physicians’ instruction and training, other factors were certainly involved. Parental support, reinforcement, and (if they are contact wearers themselves) setting a good example were key. Most importantly, self-motivation among the group was just as strong. After receiving their contact lenses, a majority of those in the survey expressed a greater confidence with and enjoyment of various activities they participated in due to the freedom from eyeglasses. Also, for a child, having to adjust to wearing eyeglasses can be a traumatic experience, since their perception of how their peers will view them oftentimes takes on a negative aspect. Self-esteem was boosted when they equated wearing contacts with enhancing their appearance.
Corroboration for the above findings was offered by another study, the Pediatric Refractive Error Profile (PREP)*, conducted over a three-year period at five US clinical facilities. In a random group of 484 youngsters—ranging in age from 8 to 11--PREP measured three factors related to contact lens wear: satisfaction, appearance, and activities. Their results mirrored CLIP, seeing positive data among the children in as little as one month, and added to the building evidence that pre-teens are perfectly capable of embracing the use and maintenance of contacts and reap the benefits for a better quality of life.
*Both CLIP and PREP were administered with sponsorship and support by VISTAKON, a division of Johnson & Johnson Vision Care, Inc.

Eye Fashion Trends Shifting Toward Colored Contact Lenses
It is a fact that women spend substantial amounts of money on eye shadows, eyeliners, false eyelashes and mascara. Recently, this trend has been shifting to having their eye care professionals prescribe colored contact lenses. Women are getting prescriptions for different colors and changing their looks dramatically. Commonly known as cosmetic contact lenses, these colored lenses are intended to change the appearance of the eye. These lenses are also manufactured in various powers so they can be used to correct vision problems should this be necessary. For the adventurous spirit or for someone in the mood for a style change colored contact lenses might just be the option for you.
Think about how many times you have walked into your favorite department store and strolled up to your favorite cosmetics counter be it, Clinique, Estée Lauder, Elizabeth Arden, Lancôme or any number of other cosmetic sellers. The beauticians are prepped to sell you more than you need and the “best” eye makeup products. The fortunate shoppers might make it out of there with bills of between $100-$200. If you are lucky, you might even qualify for one of those snazzy bonus gift bags full of sample products.
For less money than you would spend at your favorite beauty counter, you can visit an eye care professional and be fitted with colored contact lenses. He/she should have trials available for you to try in the colors that you like. Once you have made your decision just ask him/her for a prescription for each of the colors you want to purchase. Remember contact lenses are considered to be a medical device and therefore a prescription from your eye care practitioner is necessary to purchase them. Don’t get lured to a colored lens display in your local beauty salon. Such dispensing options are illegal and do not provide for the proper assurances that your eye care practitioner can give you once he/she has determined that your lenses are well fitted.
There are two types of colored contact lenses – enhancers and opaque. Enhancer lenses merely accentuate your natural eye color while opaque lenses will change your eye color completely. These medical devices need to be cared for and cleaned regularly.
· Always wash your hands before handling your lenses.
· Regularly clean your contact lenses.
· Store your contact lenses in a clean lens case.
· Do not reuse the contact lens solution you used to disinfect your lenses. Always use fresh solution to ensure maximum efficacy in disinfection.
· Do not use tap water for hydration, rewetting or during the lens cleaning process.
· Definitely do not use your saliva to rewet your lenses.
Now that you have your prescription and lens care instructions it is time to shop online for the best deals when replacing your favorite colored lenses. Remember that most lenses are sold in a 6-pack so avoid sites that are willing to sell you only 2 lenses. Shopping for contact lenses online can be tricky. Low prices per box are great but definitely check on the shipping fees as well so that you can calculate your true cost. Many places only offer free shipping after you have spent over a certain amount on their site. In no time at all you will have a whole new look for a fraction of what it would have cost at the department store beauty counter.
Below are just a few links that allow you to see the various colors available.

Presbyopia and Baby Boomers
There are almost 78 million baby boomers that are either currently experiencing vision difficulties in reading. Some are about to experience this very shortly. What is common to all is that they will come to know the world of presbyopia. This vision phenomenon eventually expresses itself with everyone on or about the age of 35 years. It is caused by the aging process as it relates to the natural eye lens and the muscle structure that assists it in the process of accommodation. This process is what normally allows for one’s ability to seamlessly see distant, intermediate, and near objects. Suddenly the newspaper or your favorite book becomes much more difficult to read at your usual reading distance. You find yourself stretching out your arms as far as possible to read. Then suddenly your arms are not long enough and you become frustrated because you can no longer read clearly.
If you have been a contact lens wearer for the past few years you will surely seek out a contact lens solution option instead of the usual pair of half eyes. This is when being well informed can be important. There are several options for you to consider. These include monovision, adapted monovision and multifocal lenses. Monovision is a fitting practice that uses vision principles normally used by the human brain when coordinating vision. The brain works with the principal that one of our eyes functions as our distance vision instrument while the other eye functions as the near vision and/or reading instrument. In reality neither handles that particular category of vision alone but weighs its functionality mostly on distance or near vision. All other vision, or fields of focus, is handled in varying degrees by both eyes, and when used together, or stereoscopically, the net result is excellent vision.
When considering contact lenses as a solution to presbyopia eye doctors prescribe one lens with a distance correction in one eye and another lens prescribed for reading in the other eye. Once again, stereoscopically the net result does provide for good visual acuity. However when lighting decreases as one may experience in a poorly lit room, a romantic restaurant setting or while driving at night, certain limitations of the monovision method will become apparent. In low light settings the pupil dialates to collect as much light as possible. In doing so each of the eyes will perform better for distance or for near vision. Intermediate vision diminishes enough to result in an effective loss of depth of field and contrast. Some patients can adapt to this but others elect to limit their wear of monovision based lens solutions to day light conditions.
Adapted monovision is a fitting method used by eye doctors who fit multifocal lenses but on the principle of classic monovision. By doing so they attempt to optimize upon the optical designs of the multifocal lens to maximize on the reading or distance vision that can be attained by the lens fit. The intermediate vision is guaranteed by the engineering design of the intermediate optical zone in each of the lenses on the respective eye. So in essence the eye doctor is optimizing the lens design characteristics to their fullest. No loss of contrast or depth of field is experienced with this method.
Multifocal lenses fitted in the classic method simply get fitted according to the prescription power requirement of each eye. The reading vision is in the center of the lens and various other fields of vision extending to the distance vision are achieved by way of the different concentric circles of powers within the lens design from the center out to the periphery of the zone of optics. No loss of contrast or depth of field is experienced with this method.
In all cases however it is your eye doctor who can best assess the lens type and fit that would work best for you. Ask your eye doctor if any of the above options will work for you.

The Impact of Vision on A Child's Learning
In most American classrooms, about 80 percent of what is taught is dependent upon an ability to see well. Teachers use tools to aid their teaching that include chalkboards, computer screens, projectors -- good vision is crucial to understanding and comprehending the material. Vision problems often lead to problems learning.
It is estimated that about 10 million children have undetected vision problems because of poor evaluation. Most schools test the distance vision of students, but fail to evaluate how well a child can see close objects.
To learn well, it is essential for children to be able to see quickly and process visual information, especially at close distance.

Signs that your child may be having visual difficulty:
- Avoiding close work as much as possible or refusing to do it at all.
- May attempt to do the work, but lacks a good understanding.
- Discomfort, fatigue and a short attention span.

Girls Self-esteem Improves with Contact Lenses
Findings from a three-year study conclude that overall self-esteem is improved in young girls when they wear contact lenses rather than eyeglasses.
The study was conducted at five clinical centers in the U.S. between September 2003 and October 2007. A total of 484 nearsighted children between the ages of eight and 11 – 59 percent female and 41 percent male – were assigned randomly to either wear glasses or contact lenses for the duration of the study.
The study uniquely combined optometry with psychology to demonstrate the benefits of contact lenses beyond their ability to improve vision.
“Girls are particularly vulnerable to social and psychological distress during the transitional years of early and middle adolescence and this data suggests that for girls, in particular, a switch from glasses to contact lenses may result in an improvement in self perception,” said Mitchell J. Prinstein, Ph.D., Professor and Director of Clinical Psychology at the University of North Carolina at Chapel Hill and a co-author of the Adolescent and Child Health Initiative to Encourage Vision Empowerment (ACHIEVE) Study. “This study demonstrates than an intervention as simple as switching youths’ glasses to contact lenses can help boost girls’ sense of self-worth and self-efficacy during this stage of their development,” Dr. Prinstein said.
Because researchers expected that a unique vulnerability might be present among the female participants, the results were examined based on gender.
“Contact lenses significantly improve how children feel about their physical appearance, acceptance among friends, and ability to play sports. Contact lenses even make children more confident about their academic performance if they initially dislike wearing glasses,” said Jeffrey J. Walline, O.D., Ph.D., and leader of the ACHIEVE study.
Parents and eye care practitioners should be aware of all of the benefits of contact lenses when determining what is the most suitable means of vision correction for their young patients.

Can Video Games Improve Vision?
A research study performed by a team from the University of Rochester has found that playing action video games can improve aspects of vision in adults.
Contrast sensitivity, which is often impacted by ageing and by conditions such as lazy eye, can be improved by playing action video games, the study found. Improvements to contrast sensitivity generally require changing eye optics through surgery or with the use of prescription eyeglasses or contact lenses.
The research compared “expert” video game players who played games involving shooting at virtual targets with players who played non-action video games. Those who played the action games had better contrast sensitivity, according to the research.
The visual improvements that were noticed in the study’s participants were sustained over the course of months and years, seemingly refuting the long-held belief that time spent in front of a television or computer screen is harmful for one’s vision.
Dr. Daphne Bavelier, who was the lead researcher on the study, said that she believes several facets of video games contributed to the results. While playing action-filled video games, players are required to be constantly ready to react to unpredictable events and players must respond instantly to visual information. Dr. Bavelier is hopeful that further research could lead to new, more efficient ways of treating lazy eye. By using video games, both eyes can be encouraged to work together to restore the vision that is lacking in people who have lazy eye.

Protect Your Children's Eyes!
A recent survey of 2,000 adults found that 82 percent of parents ensure that their children wear sunscreen to protect their skin from the sun and its damaging UV rays, but only 32 percent make them wear sunglasses to protect their eyes.
Children have larger pupils than adults and tend to spend more time outdoors; as a result, they can be exposed to as much as three times as much ultraviolet radiation.
Outdoor activity and sunshine are beneficial to children, but it is important to be well informed about the risks to ensure the health and safety of the child.

Buying the Best Sunglasses
- Be sure that any glasses you purchase have a UV-protection sticker, and it is best if they also have the American Optometric Association's Seal of Acceptance. These stickers indicate that the glasses block 99 to 100 percent of harmful UV radiation.
- Buy real sunglasses to provide real protection. Toy sunglasses aren't effective enough.
- Sunglasses should block 75 to 90 percent of light. Lenses should be dark enough that you cannot see your child's eyes through the lens.
- Gray-colored lenses are best as they absorb all colors evenly and allow the wearer to continue to see in natural color.
- The glasses should be large enough or have a wrap-around style that helps to block rays that might enter the eye from the side.

The Costs of the Aging Eye
Visual disorders that affect Americans older than 40 cost the United States economy an estimated $35.4 billion a year, according to a report in the Archives of Ophthalmology journal. The breakdown of those costs indicates an estimated $16.2 billion in direct medical costs; $11.1 billion in other direct costs; and $8 billion in productivity losses.
One of the most cost-effective ways of dealing with eye disorders is to get proper treatment and to have regular eye exams to catch problems before they become serious or untreatable.
Entrepreneur.com claims that every seven seconds a baby boomer turns 50 years old, making people over 50 a segment of the population that is expected to grow by 25 percent over the next 10 years.
Presbyopia is an age-related vision change that causes an individual, generally older than 40 years, to lose the ability to see objects at a close distance. Common symptoms of presbyopia include holding a book or newspaper at arms length in order to read it properly and feeling eyestrain or headaches when doing close work such as sewing.
Presbyopia can easily be controlled with corrective lenses, either eyeglasses or contact lenses, or through corrective surgery. Presbyopia is caused by a change in the ability of the lens of the eye to change its shape and focus on objects that are nearby.
Contact lenses are an excellent option for people with presbyopia. Multifocal contact lenses are prescribed commonly. Multifocal lenses have a range of powers in each lens.
Multifocal lenses work differently depending on their design. With alternating vision lenses, the eye alternates between powers as gaze shifts direction. With simultaneous vision lenses, the eye looks through both distance and near powers simultaneously.
If you are experiencing difficulty focusing or having any other vision issues, please contact your eye care practitioner and schedule an exam. Contact Lens King is both aware of and prepared for the increase in cases of presbyopia. It has a vast stock of numerous types of multifocal contact lenses in all standard parameters.

Eat Well for Better Vision
New research indicates that certain nutrients may be crucial in lowering the risk for developing macular degeneration, which is the leading cause of blindness in Americans older than 55.
Although the risk of eye problems increases as one ages, studies suggest that eating the right foods may lower the risk.
In a study that examined data from 4,000 participants, it was found that those who ate foods rich in vitamins C, E, omega-3 fatty acids, and the antioxidants lutein and zeaxanthin had lower risks.
Results from other studies published in the journal Archives of Ophthalmology found that omega-3 fatty acids can protect against macular degeneration; those who ate one serving of fish a week had a 31% lower risk; two servings of nuts reduced risk by 35%. Risks were lowered by 52% for those who included the highest amounts of olive oil into their diets.

Healthy Habits:
- Eat leafy greens such as kale, spinach, turnip greens and collard greens. These foods are filled with lutein and zeaxanthin, antioxidants shown to help protect against macular degeneration.
- Eat omega-3s! Foods that contain omega-3 fatty acids are known to be healthy for the heart, brain and for vision. Anchovies, mackeral and wild-caught Alaska salmon are rich in omega-3s. If you can't bring yourself to eat fish, a fish-oil or omega-3 supplement will help.
- Studies have found that exercise is good for the eyes. Researchers noted that men who ran more than 2 1/2 miles every day reduced their risk for age-related macular degeneration by up to 54%.

Protecting Your Eyes From Ultraviolet Radiation
Ultraviolet rays are invisible light rays from the sun that carry more energy than visible light. This invisible radiation is also produced from tungsten lamps, welding arcs, and certain fluorescent lights. Ultraviolet radiation (UVR) can damage a person’s eyes and skin.Sunlight and UVR can reach the eye by direct viewing, scattering from the sky, or reflection from objects such as the ground. Direct sunlight is not a major ocular health concern because not many people stare directly into the sun. The eyebrow also helps shade the eye when a person is facing the sun. Reflected light is more crucial to eye health. Fresh snow reflects as much as 85 percent of UV rays. Other reflective surfaces such as sand and water can be dangerous; the reflected rays can reach the eye even when a hat is worn.
UV radiation is divided into three categories: UVA, UVB, or UVC. UVC rays are almost entirely absorbed by the Earth’s atmosphere. The cornea and the lens of the eye absorb UVB rays. These rays do not penetrate the retina in the back of the eye, but can alter the eye’s lens and cause cataracts if the eye is not adequately protected. UVA radiation has lower amounts of energy than UVB rays, but is capable of penetrating deeper into the eye and damaging the retina, which can lead to macular degeneration and blindness.
According to the World Health Organization, 80 percent of UVR exposure occurs by the time a person reaches 18. Children have larger pupils and tend to spend more time outdoors than adults, which can lead to as much as three times more UVR exposure annually.
According to research conducted at the University of New South Wales, ocular changes can begin in children as young as 9, and 80 percent of Australian children had signs of eye damage by the time they reached age 15. One Australian school district mandated sunglass use in elementary-aged students. However, 65 percent of elementary schools in the United States prohibit sunglasses.
The UV Index, developed by the National Weather Service, the Environmental Protection Agency, and the Centers for Disease Control, estimates the amount of UVR that will reach the Earth in a certain location. High-risk periods are between 10 a.m. and 4 p.m. and at noon UVR can be 10 times higher than three hours earlier or later.
The Earth’s ozone acts as a shield against UVR, which can cause sunburn, skin cancer, keratitis and cataracts. Over the next 10 to 20 years, scientists predict the ozone may be depleted by as much as 20 percent. Holes in the ozone layer have already been located at both poles. Research conducted at the University of Houston College of Optometry has found radiation levels are unhealthy 90 percent of the time during the summer in the southern United States.
Effects of UVR
The effects of UV exposure on eye health are cumulative and symptoms can be delayed for years, and in some cases decades, making it more difficult to promote the need for protection.
In addition to the increased risk of cataracts and macular degeneration, overexposure to UV rays can also lead to pterygium, an abnormal growth on the conjunctiva that can eventually spread onto the cornea and require surgery. Pterygium is the most prevalent UV-related disease of the conjunctiva. Researchers estimate that pterygium affects more than 10 percent of the population in the southern United States and around 20 percent of central Mexico’s population. Skin cancer around the eye and photokeratitis, a painful sunburn of the cornea, can also result from overexposure to harmful UV rays.
Protecting the eyes
One of the most critical components of protection is education. In a 2005 Brand Health Monitor Report, eight out of 10 eye care patients said they wanted to know more about the impact of UV radiation.
All lenses can be manufactured with UV protection, including prescription eyeglasses, safety and sport goggles, and contact lenses.
The optimal protection against UVR is the combination of sunglasses, a wide-brimmed hat and, for those who use vision correction, UV-blocking contact lenses. The average contact lens blocks 10 percent of UVA rays and 30 percent of UVB rays. Lenses which meet the standards of the American National Standards Institute block 99.8 percent of UVB rays and 70 percent of UVA.Discuss the risks associated with UVR with your eye care practitioner and find out if UV blocking contact lenses are appropriate for you. It is important to remember that ultraviolet radiation can damage the eyes. Children’s eyes are especially susceptible, so be sure to adequately protect them.
