Bioptic and Telescopic Glasses

Many of our patients visit Dr. David L. Armstrong, Low Vision Optometrist using public transportation, a car service, or by hitching a ride from a friend or family member because they thought their uncorrectable low vision precluded them from ever being able to drive. However, this is not true. Our optometrist specializes in providing low vision aids like bioptic glasses fitted with telescopic lenses, which are permissible for driving in the state of Virginia. 

How do Bioptic Glasses Work?

Bioptic glasses, as the prefix, bi suggests, consist of two small telescopes mounted atop the upper portion of an individual's prescription glasses. When the wearer is doing close work, he or she can look below the two telescopes through the prescription portion. Should the patient need telescopic vision, such as to see the face of a familiar person across the street, watch television, or drive to the store, he or she can flip the bioptic glasses down to look through them. 

Driving with Telescopic Lenses

Virginia law requires corrected vision of at least 20/200 through the lower prescription lens, known as the carrier lens. Additionally, the individual must be able to see 20/70 or better through at least one of the mounted bioptic glasses. Furthermore, the bioptic telescopic lenses must be mounted on the carrier lens whenever the individual is at the wheel. Horizontal vision must also be at a field of at least 70 degrees. If this is not possible, the other eye must be capable of seeing 40 degrees temporal (outward) and 30 degrees nasal (inward).
