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.
