Tròng kính đổi màu là gì?

Photochromic lenses are special eyewear that darken when exposed to sunlight and become clear indoors. They adjust automatically, giving you the convenience of sunglasses without needing a separate pair. These lenses are made with unique materials that react to ultraviolet (UV) rays, causing them to change color.

How Do Photochromic Lenses Work?

The secret behind photochromic lenses lies in their molecules. When UV light hits the lenses, the molecules change shape, absorbing more light and causing the lenses to darken.

The Science in Simple Terms

  • UV Exposure: UV rays activate the lenses.

  • Molecular Change: Lens molecules shift shape.

  • Darkening Effect: Lenses absorb more light, becoming tinted.

  • Reversibility: Without UV light, lenses return to clear.
