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.
