Improving Vision

The JORDY (Joint Optical Reflective Display) device enables people with low
vision to read, write, watch television, locate objects, zoom in, and more.

people with low vision see at distance and up close. JORDY can be operated in
vivid color, black and white, high contrast positive, or high contrast
negative. It is lightweight (8oz) and includes a Compact Control Unit. $2800
