Do Contact Lenses Cause Extreme Redness?

 Extreme eye redness can be from contact lenses. The use of contact lenses can lead to conditions that cause extreme redness. You might wear them too long, get something underneath a lens or have a more serious infection like keratitis. Although many people wear contacts without problems, there are risks associated with their use.

Dry eye syndrome is more than just an inconvenience. It means your tears, or lack of tears, cannot produce the lubrication your eyes need. If eyes become too dry, contact lenses will create eye friction. Their use may even be the cause of your dry eye symptoms leading to redness and pain. Use re-wetting drops or wear the lenses for less time to solve the problem.
People can be allergic to contact lenses. You might be sensitive to a material they are made from, a chemical in them or to the protein deposits that build up on them. This allergy may develop over time even if you have been wearing contacts successfully for awhile. Soft lenses pose a higher risk for allergies than hard ones.
Keratitis is an inflammation of the cornea that might occur from wearing contacts, according to the Mayo Clinic . A non-infectious version happens from leaving them in for too long a period of time. You can also get an infectious type of this condition from foreign objects, a virus or even parasites settling in your eyes.
