Contacts Match Active Lifestyles at All Ages

In recent decades, Americans have become more active as they try to live a healthy lifestyle. Whether it is competitive sports or leisurely pastimes such as jogging, walking, or swimming, we are going and doing in greater numbers than our grandparents. However, if you are among the millions who require vision correction you have another concern: finding the type of lenses that won’t inhibit your activity level or enjoyment.

Although tolerated for years, eyeglasses remain pretty much a non-starter as far as being the best means for seeing well while exerting yourself. There are many disadvantages: restricted peripheral vision, slipping or falling frames, putting up with spectacle headbands, accommodating goggles, etc. Oftentimes glasses are the main reason people opt not to take up a sport.

Contact lenses have certainly made it easier to participate in physical activities, with their convenience and range of choices. Also, because of recent studies showing that responsible children can be successfully fitted for contacts, the entry age for kids who need vision correction and wish to start playing sports now begins at approximately eight years old. At the other end of the scale, older or ‘more mature’ individuals are able to continue enjoying healthful exercise with contacts that have come a long way in addressing eye conditions related with age, primarily presbyopia and dry eye.

Between the two types of contacts favored today, soft and gas permeable (GP), soft contacts get the nod as the better choice when it comes to active wear. Besides being more comfortable and quicker to get used to, their gel-like make-up allows them to adhere to the eye in such a way that they do not fall out during exercise or strenuous activity. Gas permeable contact lenses, because of their rigid and smaller-diameter design, tend to move or dislodge as the body exhibits vigorous motion. A recent development, hybrid lenses, may make it easier for those who are bound to a GP contact. Hybrids blend the corrective qualities of GPs with the comfort of soft lenses.

Disposable lenses have been a boon to sports enthusiasts who find themselves in situations where a strict contact-cleaning regimen is unwieldy, i.e. camping, sailing, or hunting excursions that can last for days. Beginning with a fresh pair every day and discarding them before retiring for the night, disposables are seemingly made for those constantly on the go.

Nowadays there are eye care practitioners who can specifically fit for participants in competitive or professional sports. Adapting general fitting techniques to the more precise need of a particular activity accomplishes this, whether it is softball or soccer for school-age children or golf and tennis that appeal to an older crowd.

Be mindful that any change in eyewear you plan to make is done in close consultation with your eye doctor. This is necessary to arrive at the proper lens for comfort and ease that will allow an enhanced enjoyment of your activities.

Contact Lenses and Solutions

Conscientious contact wearers are fully aware that taking proper care of their lenses is important and vital to continued eye health. The cleaning and storing regimen is a major part of this care.

There are various types of solutions made to accomplish safe cleaning and storage and it is easy to become confused about which does what. The following breakdown may be helpful.
· Cleaning solutions remove bacteria and debris, including dirt and mucous.
· Disinfecting solutions are used when storing your lenses, killing bacteria when you are not wearing your contacts.
· Multi-purpose solutions combine cleansers with disinfectants and can be used to remove proteins on lenses that come from tears.
· Peroxide solutions are also disinfectants, but most importantly come with a neutralizing agent that must be employed to convert the peroxide to saline before contacts can be placed on the eye. Peroxide in the eye will cause serious injury.
· Enzyme cleaners and protein removers target tear deposits that may irritate eyes.
· Rewetting solutions moisten lenses during the course of the day as they become dry; also called comfort drops, they can extend lens wear.
· Rinsing solutions basically wash across lenses to ready them for use, but do not kill bacteria.

Solutions should not be kept beyond their expiration dates; neither should they be mixed unless okayed by a doctor.

With all the above information, not to mention expense, an obvious question would be why not use tap water as a cleanser? Because despite the best filtration systems, tap water carries microorganisms and bacteria that can cause serious eye infections such as Acanthamoeba keratitis, a parasite-triggered condition that is sometimes difficult to diagnose and leads to permanent vision loss if allowed to advance. Bottled and distilled water are also off limits as impromptu solutions for the same reason.

It is also important to remember that swimming pools, hot tubs, and other recreational waters pose the same potential health risks if water is splashed in the eyes while wearing contacts. If this happens, remove the lenses as soon as possible, rinse and store them overnight to a proper disinfecting solution. A way to avoid this problem, especially if you are a ‘water-loving’ person who has no solution handy, is to carry disposable contacts. Disposables can be discarded and replaced once you leave the pool, lake or tub.

As for selecting the right solution for reusable lens care, your eye doctor is the person to go to for the information you need to navigate the various types and brands available. In fact, consultation is vital for first-time contact wearers and those wishing to switch from an established care regimen.

You enjoy the comfort and convenience provided by contacts. By approaching the cleaning and care aspects in an informed and responsible manner, you will ensure your healthy enjoyment of lenses for years to come.

Dry Eye Syndrome in Regards to Contacts

If your eyes have feelings of dryness, scratching, burning, or the sensation that something is in your eye, then you may be suffering from dry eye syndrome (what doctors call keratitis sicca). It is basically diminished amount of moisture due to evaporation or rapid draining of the tear film on the eye; it can also refer to a lack in the quality of tears, as they are made up of three components: oil, water, and mucous.

Some factors that lead to dry eye include the natural aging process; side effects from medications; dry, dusty or windy climates (don’t discount indoor ‘climates’ such as home or offices affected by air conditioning or heating systems that dry out eyes); smoking; and insufficient blinking caused by concentrating on computer screens and the like. There are also health conditions that can play a role: eye gland disorders, rheumatoid arthritis, and diabetes.

Contact lens wearers can also fall into a pattern of dry eye, as this is a complaint from roughly 50% of users. However, combinations of treatment and types of lenses made to offset dry eye means one does not necessarily have to give up contacts.

First, if you suspect dry eye problems visit your eye doctor for a full examination to determine the type and extent of the disorder. From there, a treatment plan can be established. In recent years, developments both with contact lenses and other products have brought new weapons to the dry eye front.

Among the contact lens brands in this regard are Acuvue Oasys, Focus Night & Day, Ciba O2 Optix, Acuvue Advance, Bausch & Lomb PureVision and Proclear Compatibles. Using these lenses alone or in combination with doctor-approved eye drops or prescription medications have helped many with dry eye. Drops with cyclosporine in a castor oil base aid the body in producing more tears; this is more popularly recognized as Restasis. Other measures that can be taken include maintaining good care of your lenses, being more mindful about blinking frequently and completely throughout the day (which keeps up the natural wetting process), and re-soaking the lenses in solution for a few minutes to extend comfortable wear time.

When it comes to producing tears with the proper consistency, nutrients such as omega-3 fatty acids and oils gleaned from fresh-water fish are helpful. Flaxseed oil is also recommended.

Surgically, there is a process where punctal (also called lacrimal) plugs can be inserted in the tear ducts to slow the draining of moisture from the eye. The process is painless and usually the plugs are not felt after they are in place. There is also an insert that can be set inside the lower eyelid that releases a lubricating agent throughout the day.

With contact lens manufacturers, medical researchers, and other professionals continuing to look for better ways to minimize or eliminate dry eye syndrome, it is only a matter of time until discomfort from this problem becomes a thing of the past.
