AI Technical Summary
Traditional lens designs cause glare when light shines directly into the eyes, which current technologies cannot effectively eliminate and may sacrifice light efficiency or introduce stray light.
Anti-glare lenses with indirect light emission design are designed with light-inlet, light-reflecting, and light-emission surfaces. Light is reflected by the light-reflecting surface and output from the side, forming an indirect light emission path. Light is controlled by densely arranged optical microstructures or electroplated reflective layers.
It significantly reduces glare, prevents direct light from hitting the eyes, improves light efficiency, and is suitable for a variety of lighting scenarios.
