Light Flicker Canceling Glasses

摘要

Most electric light sources flicker, that is, the intensity of the light that is produced varies substantially in a periodically repeating pattern. In sensitive individuals, light flicker can cause headaches and other undesirable symptoms. This invention comprises a light sensor that measures light intensity, signal processing that identifies the flicker component of the light, and electrically controlled lenses of glasses (spectacles) that rapidly darken or become more transparent so as to cancel most of the flicker. This reduces the flicker seen by the wearer of the glasses, reducing discomfort.

主权项

1. Glasses (spectacles) having lenses with variable light transmission density that is controlled by an applied electric voltage, a light sensor capable of sensing visible light and having a fast response time, and amplification and control circuitry suitable for controlling the voltage applied to the lenses so as to cancel the majority of the flicker that is present in the incident light.
