Abstract: A lens assembly and Augmented Reality (AR) glasses, including a waveguide substrate, a wiring layer, a protective layer, an eye tracking component, and a lens. The waveguide substrate includes a first surface. The wiring layer is disposed on the first surface. The protective layer is disposed on the first surface and covering the wiring layer. The eye tracking component is disposed in the protective layer and is electrically connected with the wiring layer for tracking position of an eyeball. The lens is connected to a side of the protective layer away from the waveguide substrate. The AR glasses includes a display device and two lens assemblies. The display device is positioned between the two lens assemblies for emitting image light to the waveguide substrates of the two lens assemblies.

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.

Abstract: Embodiments of the present disclosure relates to an optical lens and a HUD using the optical lens. The optical lens includes a first lens, a second lens, and an optical waveguide. The first lens includes at least two focal parts with different powers. Since the HUD utilizes the optical lens, the user can maintain a comfortable viewing effect when wearing the HUD for a long time.
