摘要
When mounted in glasses the device consists of photosensitive detectors (2), an electronic circuit (3), two electro-optical filters (5,6) with active zones (7,8), electrical connector (4) linking the circuit (3) and the active zones (7,8). The detectors (2) generate a continuous signal with its power a function of received light. The electrical circuit (3) generates an alternating signal with frequency and/or amplitude varied with the output delivered to the filters (5,6), comprised of liquid crystal arrays (15 in fig 2). The active zones (7,8) are positioned in front of the users' eyes.
