Transitions XTRActive lenses are the newest addition to the family of Transitions lenses. These everyday lenses are designed for wearers who prefer a slight tint indoors and very dark lenses outdoors.
 
Do Transitions XTRActive lenses activate while driving? Yes, Transitions XTRActive lenses have an average darkness of 53% and can achieve up to category 2 darkness1 behind the windshield to protect eyes from sunlight while driving.
 
Transitions® glasses automatically adapt to changing light conditions. Responding to the light around you, they intelligently change from clear to dark when you go outdoors and back to clear when you return inside. All Transitions® lenses block 100% of UV rays and help protect against harmful blue light from digital devices, screens and bright sun.
