Abstract:
An optical system is provided. The optical system includes an electronic display, an adaptive lens assembly, and an eye tracking device. The electronic display displays a virtual scene for a user of the optical system; the adaptive lens assembly is optically coupled to the electronic display between the electronic display and eyes of the user; and the eye tracking device provides eye tracking information of the eyes of the user. The adaptive lens assembly includes a plurality of adjustable liquid crystal (LC) lenses arranged in an array, and the adjustable LC lenses are activated individually based on the eye tracking information.
