Allergy to Contact Lens Solutions
After using a contact lens
solution for a long time, possibly years, you may become suddenly allergic to
it. The offender is usually the preservative a chemical that prevents the
growth of bacteria and other germs. The federal Drug administration (FDA)
requires that all eye drops and solutions intended for more than one time use
contain a preservative. The requirement applies to all sterilizing, cleaning,
and storage solutions.
Symptoms
The first symptoms of
allergies are likely to be itching and burning in your eyes and a decreasing
tolerance to wearing the contact lenses. Later, your eyes may become red, and
stay re even after the lenses have out for a while. Other symptoms include
swelling of the injunctive (the membrane over the white of the eye), small
lumps under the eyelid, and a mucus discharge your contact lenses may be
smudged, and coated with deposits that increase in quality almost daily.
Treatment
As a first step, stop
wearing your contact lenses, at least for a little while. You may be given a
prescription for an anti-allergic eye drop to be used until the allergic
reaction quiets down.
When your eyes do clear
up, you will have t9o take care of your contact lenses in a different way,
completely avoiding the offending chemicals, which are most commonly
chimerical, chlorhexidine, or some form of sorbet, such as ascorbic acid. We
will help you choose both a cold sterilizing and lens cleaning method that is
free of those chemicals, or an allergy free heat sterilizing method using
preservative free saline. This is available in several forms.
