Oversized Contact Lenses Help People With Cornea Problems

Oversized contact lenses can be of significant help to those sight-impaired with cornea irregularities. The lens fits on the sclera (white of the eye) just under the lid and forms a liquid bandage around the surface of the cornea. Light is allowed to pass through the soft lens as well as oxygen. Once this product is perfected, they could benefit 60,000 people in the United States alone.

The larger sized contact lens is a permeable rigid contact about the size of a quarter. It rests on the sclera area of the eye and forms a soothing liquid bandage over the diseased cornea. The eye's natural tears helps seal it from outside to protect the cornea from light and helps relieve pain associated with dry eyes. This sealed environment allows a diseased cornea to function better and see much clearer.

Oversized contacts need to be cleaned just like any other type of contact lenses. People that wear contacts are more prone to serious eye infections due to the touching of fingers on the surface of the eye. If you notice redness developing in your eyes along with blurred vision and light sensitivity, take your lenses off and disinfect them. Daily-wear lenses can be cleaned at night and put back in the next morning. If you use extended-wear contacts, be sure to take them out and clean them if irritation persists longer than 2 to 3 hours. To be on the safe side, many people take their extended-wear contacts out to clean them during the 30-day time span even though they may not have to.
