Eye Allergies and Contact Lenses

Allergens are attracted to contact lenses. The lens can function like a sponge and attract deposits and allergens. The body's response to allergens causes nearby cells to release chemicals that result in inflammation. There are also some substances found in contact lens solutions that can lead to this response, causing redness, itching, mucous discharge, and discomfort. 
The chemical thimerosal is most commonly associated with eye allergies, though other chemicals can also cause an allergic response. Reactions can develop at any time, even after several months or years using a solution.

To avoid an allergic reaction to contact lens solutions, it is wise to use products labeled "sensitive eyes" or "thimerosal free." Check the product label to be sure that the solution does not contain chemicals you may be allergic to.

How else can you get through some of these symptoms?

• Decrease the lens wear time and wear eyeglasses when possible.
• Clean your contacts often.
• Keep your eyes moist with artificial tears.
• Frequently wash hands with soap and water.
• Wash bedding in hot water to reduce allergens.
• Avoid wearing eye makeup.
• Use cool compresses on your eyes when they are red and swollen.
• Resist the urge to rub them.
• Consider changing the lens type. A period of weeks to months without any lens worn is often helpful in controlling this problem.
• Daily disposable lenses avoid the buildup of allergens on the lens surface and also eliminate exposure to disinfecting solutions and lens cleaning products that may also lead to allergic reactions.
