Tips For Treating And Living With Nearsightedness

Modifying Contact Lenses

One of the most frequent forms of treatment is through modifying contact lenses. Contact lenses use the same prescriptions as glasses. Like glasses, the lens changes the way light enters the eye, allowing the eye to focus properly. Contact lenses are significantly thinner than eyeglass lenses. Some patients prefer them because they eliminate the need for glasses, though others experience some discomfort. A contact lens rests directly on the surface of the eye. Glasses, by contrast, are about a half inch away from the face. Since contacts are much closer to the eye, they don't need as large an optic zone. With eyeglasses, the optic zone includes the entire surface of the lens. Contact lenses only have a small portion of the lens dedicated to the optic zone, while the peripheral curves have no effect on an individual's vision.
