Abstract
An optical sensor includes a light source emitting signal light, a light sensing element on an optical path of the signal light, and a photoelectric conversion element on a side of the light sensing element away from the light source. The light sensing element is used to receive ambient light and the signal light on one side and transmit an incident light on another side, wherein a transmittance of the light sensing element changes according to an intensity of the ambient light to adjust an intensity of the incident light transmitted from the light sensing element. The photoelectric conversion element is configured to receive the incident light transmitted from the light sensing element, and to output a voltage modulation signal according to the incident light. A glasses is also provided.
