Abstract
The utility model discloses sun glasses applied to the technical field of glasses. The adopted scheme is as follows: a light intensity detector is used to detect the variation of external light strength; and a microprocessor calculates out duty cycle (which is the ratio between the time a left liquid crystal lens and a right liquid crystal lens are opened to penetrate light and the time the lenses are closed to stop light) based on the detection results on the external light strength detected by the light intensity detector, and simultaneously provides or not provides corresponding voltage to the left and right liquid crystal lenses to control the simultaneous open/close of the left and right liquid crystal lenses. When the calculated duty cycle increases, the light transmittance of both the left and right liquid crystal lenses is high and the light transmittance of the sun glasses is high, vice versa, thus the light transmittance of the sun glasses can vary along with the variation of the external light strength, and the sun glasses can adjust the light transmittance based on the variation of the external light strength in a self-adaptive way to meet sense requirements of people on different external lights.
