What Kind of Infections Can Contact Lenses Cause?

Contact lenses are generally quite safe, but some people end up with infections. The most common type of infection is keratitis. Keratitis is an infection of the cornea, the part of the eye your contact lens covers.

Keratitis is also the most dangerous infection because it may cause scars on the cornea. This can ruin your vision and may require a cornea transplant.

You may also contract conjunctivitis through the use of unclean contact lenses. The disease is more commonly known as pink eye and may be caused by having a foreign object, such as a contact lens, in your eye. While it may not cause permanent damage, it can be very uncomfortable. You may have discharge and a burning sensation. Your eyelid may swell and turn pink, as well.

How to Prevent an Eye Infection

In many cases, eye infections are linked to improperly handled contact lenses. If your lens is torn, cracked, or scratched, it can harbor bacteria. The uneven surface of a damaged lens is more likely to scratch your eye and deposit the bacteria in the open wound.
