Augmented reality optical lens with eye protection function and preparation method therefor

Abstract

The present disclosure provides an augmented reality optical lens with eye protection function and a preparation method therefor, addressing the issues of heat dissipation and eye protection in head-mounted display devices. The lens uses silicon carbide as a substrate, with specific optical thin-film structures on both sides. When the device generates heat, a heating element is connected to the lens by means of a thermally conductive tape, and the heat is dissipated by utilizing a thermal conductivity of silicon carbide. Heat dissipation is enhanced through heat exchange with air and by regulating a direction of infrared radiation, preventing human eyes from thermal radiation. The present disclosure integrates heat dissipation and eye protection functions, features a simple process and high yield, meets the demands for miniaturization, long battery life, and eye protection in head-mounted devices, enhances user experience, and promotes the development of augmented reality technology devices.
