abstract:BiOptics, also known as a biOptic in the singular, and sometimes more formally termed a biOptic telescope, is a term for a pair of vision-enhancement lenses with extreme magnification, used to improve distance vision for those with severely impaired eyesight, especially those with albinism. They may take the form head-mounted eyeglasses similar in appearance to goggles and binoculars, although several brands are designed to be attached to existing glasses rather than being a self-complete form of eyewear.
