To magnify distance objects, telescopic systems are frequently used. These may be handheld or mounted in eyewear called bioptics. Thousands of mildly visually impaired patients in the United States use bioptics to drive, watch television or do other distance tasks.  Beecher Researchís telescopic system, the Beecher Mirage, is a lightweight binocular system that is worn like eyewear for distance viewing.  We have found it to be an exceptional aid to view television even in patients with visual acuities below 20/600.   

Telescopes may be attached to prescription eyewear to create what is called a bioptic system. Bioptic eyewear design has evolved from large telescopic tubes to smaller, more cosmetic telescopes. Modern bioptic design includes many, small lightweight systems that have improved patient acceptance such as the Vision Enhancement System introduced by Ocutech ten years ago.[i]

Recently, Ocutech has introduced an auto focus version, the VES-Autofocus. It is a monocular 4X bioptic telescope mounted above the eyeglass frame. Powered by a rechargeable battery, it contains two computer chips and an infrared focusing system similar to that found in an auto focus camera. VES-Autofocus can focus automatically from 12 inches to infinity in a fraction of a second, and has dramatically changed the purposes for which we prescribe bioptics. Rather than being used for one or two specific tasks, these systems are being worn fulltime and more importantly, the patients using this system regain a sense of personal space and an ability to better interact with people. They can again see facial expressions and notice body language, subtle yet important aspects of everyday communication.[ii]
