Contact Lens Problem

Improve Your Vision Without Glasses or Contact Lenses: The AVI Program by American Vision Institute,

For the 110 million Americans who suffer some type of vision problem, the American Vision Institute offers a clinically proven program of 20 exercises and maintenance techniques guaranteed to improve vision in as little as 30 days. This complete course in vision therapy helps increase focusing power, decrease eye strain, and prevent further deterioration of vision. Illustrated.

Contact lens - Contact lenses (also known simply as "contacts") are lens placed on the cornea of the eye usually, but not always for corrective purposes. They serve the purpose of conventional glasses, but are very light and convenient, sitting directly on the eye.

Corrective lens - A corrective lens is a lens worn on or before the eye, used to treat myopia, hypermetropia, astigmatism, and presbyopia. The most common types of corrective lenses are spectacle lenses and contact lenses.

Lens sag - Lens sag is a problem that sometimes afflicts very large reflecting telescopes. It occurs because the very weight of the glass leads to a distortion in the shape of the lens.

Scleral lens - A scleral lens is a large type of contact lens that rests on the sclera and creates a tear-filled vault over the cornea. Scleral lenses are designed to treat a variety of eye conditions which do not respond to other forms of treatment.
