Do Transitions XTRActive lenses activate behind the windshield?
Yes! They do not get as dark as sunglasses, but they do provide a meaningful level of tint to drivers. In fact, 72% of wearers who have tried Transitions XTRActive lenses are satisfied with them when driving in very sunny conditions. Transitions XTRActive lenses activate under both UV and visible light, which is why they get darker and activate behind the windshield. This is also the reason why there is a slight indoor tint—something that makes Transitions XTRActive lenses different than Transitions VI lenses. Please note that the performance of Transitions XTRActive lenses behind the windshield may be influenced by a variety of factors, including the position of the driver in the car, the shape and inclination of the windshield, and characteristics of the glass used to manufacture the windshield.
