Abstract
A person's sight may be seriously damaged when high levels of coherent light impinge upon one's eyes. In order to protect against this, a visor or windshield is equipped with a first layer of photosensor segments respectively and optically aligned with corresponding light-blocking segments which take the form of LCD material or photorefractive glass. Wherever light impinges upon photosensor elements, at levels above a preselected threshold, the corresponding light-blocking segments are switched to a light-blocking mode. The end result is the blocking of harmful light in only those portions of an entire field of view where harmful levels of light radiation exist.
