Corrective Lenses
Introduction
 Overview of Refractive Disorders can be corrected with glass or plastic lenses mounted in a frame (eyeglasses) or with a small lens made of plastic floating or resting on the cornea (contact lens). Good vision correction is possible with either eyeglasses or contact lenses. For most people, the choice is a matter of appearance, convenience, cost, risk, and comfort. Aids for coping with vision loss (referred to as low-vision aids) can be an enormous help to people with only partial vision. Low-vision aids for reading, writing, watching television, and engaging in outdoor activities include the following: Large-print books Large-numbered telephones, clocks, watches, and thermometers Closed-circuit television to magnify objects Electronic "talking" clocks and other "talking" devices Computer programs that can scan text and then produce larger text or read the text out loud Light filters to improve contrast Color-coded pill boxes Handheld magnifying glasses Glare-reducing sunglasses Handheld binoculars Eye doctors working with other health care practitioners can usually evaluate how vision loss affects a person. They can then recommend a combination of low-vision aids that they believe would best help the person do daily tasks.
