Eyeglasses For centuries people have been using glass lenses to assist in correcting poor vision. The principle hasn’t changed, but the sophisticated modern eyeglass lens has come a long way since its beginning seven centuries ago. Today eyeglasses are used to correct vision problems such as short-sightedness, far-sightedness, astigmatism, and presbyopia by focusing light more accurately upon the retina. The type of vision problem you have will determine the shape of the eyeglass lens prescribed for you. What used to be a simple single-vision lens those many centuries ago, can now contain two or more vision-correcting prescriptions known as progressive lenses. And to lighten the burden for the wearer, plastic lenses are available along with high-impact resistant polycarbonate lenses for safety at work and play.
