Contact Lenses Directory

A contact lens is a small plastic or silicone disc-shaped lens that is placed on the cornea of the eye to correct eyesight problems. Contact lenses may also be used for cosmetic reasons -- for example, to change the appearance of eye color -- or they may be prescribed following cataract eye surgery. Millions of people wear contact lenses without any problems. But it is important to follow directions for proper lens care carefully to avoid vision-threatening complications. Follow the links below to find WebMD's comprehensive coverage about contact lenses, how to wear them, how to care for them, and much more.
