Light Adaptive (Photochromatic)

Our light adaptive photochromatic lens coating is what creates ‘transition lenses’ - lenses that are clear indoors and automatically darken when exposed to sunlight.

The key to transition lenses is its special photochromic coating that is made from millions of tiny molecules called photochromic molecules. When these molecules are exposed to UV light, they undergo a chemical reaction that causes them to change shape and absorb more light, resulting in the lenses becoming darker. When the UV light is removed, such as when you go indoors or it becomes cloudy outside, the molecules return to their original shape and the lenses become clear again.

The speed of the transition from clear to dark and back again depends on the intensity of the UV light and temperature. They typically take about 30 seconds to fully darken and up to five minutes to fully lighten. Transition lenses may be available in different colours, with brown and grey being the most common. Being added easily as a lens coating for prescription glasses, they provide a convenient all-in-one solution for people who spend a lot of time both indoors and outdoors.

Benefits of light adaptive lenses include:

• Eliminating the need to switch between regular glasses and sunglasses when moving between indoor and outdoor environments
• UV protection to help protect your eyes from harmful UV rays that can cause long-term damage
• Improved visual comfort by reducing glare and increasing contrast in bright outdoor conditions
