Photochromic Lenses

How they work (education-level)

Photochromic molecules in or on the lens activate with UV (and in some products visible light), darkening the lens outdoors and clearing indoors over time. Temperature influences speed and depth of tint.

Practical limits

Many windshields block UV, so some photochromics stay lighter in the car than outdoors. Activation and fade take time—they are not instant sunglasses for a sudden tunnel. Separate sunglasses may still be preferred for bright driving or sports.

Choices and coatings

Photochromics combine with indices, AR, and polarized sunglasses (different product class). Ask dispensers about indoor residual tint preferences if you work under bright windows.
