Tròng kính đổi màu là gì?

Photochromic lenses are eyeglasses that darken when exposed to sunlight, becoming clear when inside. They are reactively adjustable, so you get the convenience of sunglasses without having to have another pair. These are made with special materials that respond to ultraviolet (UV) rays and change color.

How Do Photochromic Lenses Function?

The magic of photochromic lenses comes down to their molecules. When UV light strikes the lenses, the molecules shift shape, absorbing more light and making the lenses darken. When you step inside, out of the path of the UV light, the molecules revert back to their original structure and the lenses go clear again.

Khoa học trong các thuật ngữ đơn giản

  • UV Exposure: When the lenses are exposed to UV rays, they are triggered.

  • Molecular Change: Lens molecules change shape.

  • Blind Effect: Lenses become more tinted due to the absorption of additional light.
