Abstract
A filter test kit for low vision is provided and may include a plurality of test frames. A test frame may include two sockets, a pair of optical lens tint components disposed in the sockets, a bridge connecting the sockets; and a tactile frame identifier. The pair of optical lens tint components for each frame is different from the pair of optical lens tint components of each other frame. Also, the tactile frame identifier for each frame is different from the tactile frame identifier for each other frame.
