XTRActive Transitions lenses are advanced photochromic lenses specifically designed to provide extra protection from bright light. These lenses not only darken in direct sunlight but also achieve a moderate tint when exposed to indoor lighting or behind a car windshield, offering consistent comfort across various environments. Engineered for individuals who are particularly sensitive to light, XTRActive lenses ensure optimal visual clarity and protection, whether indoors, outdoors, or while driving. They offer a darker tint compared to standard Transitions lenses, enhancing overall light management throughout the day.
