摘要： A sunglass using a transparent, pixelated, liquid crystal (LC) two-dimensional array, or functionally equivalent technology, in possible combination with optical materials to selectively attenuate or block the Sun or its reflection from the field of view (FOV) of the person wearing the glasses is disclosed. An imaging camera located within the sunglasses detects the Sun, with software determining its position via centroiding algorithms. The Solar position is then translated, and, if necessary, rotated, scaled and skewed for the appropriate pixels in the left and right lens of the sunglass, where left eye and right eye “circles” are created to block or attenuate the Sun's image from the person wearing the glasses. Additionally, the sunglass lens will have protection against the Sun's ultra-violet (UV) rays. The internal power source may be either replaceable, or charged by solar or standard methods.
