SHIFT™

Photochromic Lenses

​Features

  • Light-activated lens technology that blocks 100% of UV light and provides powerful HEV blue light protection:​

Percentages reflect the average HEV blue light filtering & absorption across all materials & colors

  • Adapts in all lighting conditions faster than most photochromic lenses through the integration of a new, high-performance photochromic dye

​

  • Fades to clear in approx. 3 minutes, while other photochromic lenses take up to 5 minutes*​

How does it work?

Photochromic dye molecules use the energy from UV light, which triggers an equilibrium reaction to change from a closed, "clear" shape to an open, light-absorbing "dark" shape.
