  • Visor with point sun blocking
    Patent number: 4848890
    Abstract: Eye gear is provided to protect a wearer from irritating direct sunlight. Liquid crystal matrices are positioned over the wearer's eyes and a sun-tracking photosensor and related electronics determines the area of direct sunlight within the viewer's field of view. Segments of the matrix corresponding to the sunlit area are switched to a light-blocking state so that the remaining unaffected field of the view may be maintained.
