BEHIND THE WINDSCREEN
Most photochromic lenses react to UV light, however car windscreens block nearly 100% of UV light. One of the unique and special attributes of Transitions Drivewear lenses is that they darken behind the windscreen 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 colour, which many drivers find is the most comfortable colour for driving. This is not surprising, as the Transitions Drivewear lens colour was designed to both remove excess light and provide good traffic signal recognition, highlighting the reds and greens. The copper colour can also provide improved depth perception.
