Due to that I'm legally blind, I wear my Ocutech eyeglasses both on and off the bicycle. They are made by Ocutech Incorporated, a large company that makes visual devices. The prescription carrier lenses of the clear up what I'm able to see immediately around me. Meanwhile, a small, short-range telescope mounted on top of the eyeglass frames affords me a small picture of 20/20 eyesight. When bicycling, the Ocutech can easily be worn by people who choose to wear a helmet.
