AI Technical Summary

Technical Problem

Near-eye devices such as VR goggles are susceptible to adverse eye effects from unnecessary light emission, particularly infrared light, which can lead to conditions like cataracts, and existing optical laminates do not effectively mitigate these issues without impairing visibility.

Method used

An optical laminate for near-eye devices comprising an IR absorbing layer with specific light transmittance properties and functional members, including a polarizing member, phase difference members, and protective members, is designed to cut unwanted light while maintaining visibility.

Benefits of technology

The optical laminate effectively reduces the adverse effects of infrared light on the eyes, preventing conditions like cataracts and enhancing device visibility by selectively filtering out unwanted light without compromising image clarity.
