Two types of bioptic eyewear include the Beecher Mirage and the VES-Autofocus. Bioptics are essentially telescopes that are mounted or attached to prescription eyeglasses to improve distance viewing, according to LowVision.org.
Bioptics come in different designs, with some attached on the top of regular prescription glasses and others drilled into the lens itself, according to The Vision Council. Just like a telescope system, bioptics enlarge distant objects for easier viewing. Bioptics come in magnifications of 2x to 4x, and eye specialists usually prescribe them for people with low vision, such as those afflicted with albinism. Companies that fabricate bioptics include eyeFine, Ocutech and Vision Advantage.
