Photochromic Lens Principle	Principle of Photochromic Lenses 1. UV-Triggered Tinting: The lens contains light-sensitive materials like silver halide or spiropyran-based compounds, which undergo reversible chemical reactions when exposed to UV light. This causes the lens to darken, blocking intense light and absorbing UV radiation. 2. Transparency Restoration: In low or no UV conditions (e.g., indoors), the chemical structure reverts to its original state, restoring transparency for clear vision. 3. Self-Adjusting Mechanism: The entire process is automatic and dynamic, balancing optical clarity with light protection without manual intervention. Summary: The lens achieves "darkening under light, transparency in darkness" through molecular structural changes in UV-responsive materials.
