Photochromic Lenses
These are wonderful lenses for
people on the go!
- The lenses darkened for sunny outdoor activities and become clear when indoors.
- The rate of change between dark and clear has improved tremendously.
- The change from outside to inside usually occurs within 1-2 minutes.
- The light transmission inside is comparable to regular clear lenses.
- The outside darkening is very similar to sunglasses.
- Darkening depends on temperature and the amount of UV present.
- Especially valuable for light sensitive patients.
- They are available in plastic, glass & polycarbonate materials.
- Lens availability includes single vision, bifocals and progressive lenses.
- Gray, brown and fashion tints (yellow, violet, orange, blue, rose & teal) are available.
- As a general rule, photochromic lenses won’t darken behind the windshield because the glass blocks out the UV rays that cause the lenses to change color.
