BEHIND THE WINDSHIELD
Most photochromic lenses react to UV light, however car windshields block nearly 100% of UV light. One of the unique and special attributes of Transitions Drivewear lenses is that they darken behind the windshield of a car because they have the ability to react to visible light as well as UV light.
When exposed to visible light, the lens changes to a copper color, which many drivers find is the most comfortable color for driving. This is not surprising, as the Transitions Drivewear lens color was designed to both remove excess light and provide good traffic signal recognition, highlighting the reds and greens. The copper color can also provide improved depth perception.
