1. The Applicability and Principle of Photochromic Sunglasses:
Drivers often choose photochromic sunglasses to protect their eyes from strong sunlight or bright snow glare. In softer light conditions, the lenses become clear. These sunglasses adjust their tint based on the amount of UV rays, shifting to gray or brown to absorb harmful UV radiation.
2. The Functions of Photochromic Sunglasses:
Photochromic lenses offer several key features:
- Photochromic: These lenses darken when exposed to specific types of light, particularly UV radiation, and gradually return to a clear state once the light source is removed.
- Anti-Reflective: AR coating enhances light transmittance, reduces lens reflection, and eliminates stray light.
- Anti-Radiation: High-vacuum electron beam evaporation prevents electromagnetic radiation and electrostatic damage.
- UV Protection: UV coating blocks up to 99% of rays up to 400nm, protecting eyes from harmful radiation without affecting visible light.
- Scratch Resistance: Anti-resistant coating prevents scratches on the lens surfaces.
- Hard Coating: A hard coating forms a permanent bond with the lens surface, preventing heavy scratches.
