XTRActive lenses are a type of photochromic lens from Transitions that are designed to have the darkest photochromic lens option available. They are intended for eyeglass wearers who spend a lot of time outdoors or are hypersensitive to light. For these reasons, XTRActive lenses also have a very light tint while indoors, adhering to light sensitivity. XTRActive lenses block 100% of UV light, and they have a slower transition period than other photochromic lenses. They also provide what Transitions refers to as “modern tint” while inside of an automobile. “XTRActive Lenses are perfect for those of us who have outdoor occupations,” says Dr. Hodgson of FramesDirect.com. “If you spend the majority of your day outside or you are sensitive to light, sun eye protection is a necessity for you.”
XTRActive lenses are available for almost all eyeglasses, including rimless and vintage frames. They are available in Trivex, polycarbonate, single-vision, and progressive lens materials. They are also available in prescription and nonprescription form.
