The Sports Sunglasses Altalist Legacy 2 Photochromic are unique sports sunglasses with auto-darkening polycarbonate lenses, which are able to adapt to the current conditions. As a result, the lenses lighten and darken automatically based on the conditions, switching between filters of categories 0-2.
Made of Grilamid TR90, the frame is not only durable but also extremely light. The adjustable nosepiece and rubber-coated earpieces allow for a perfect fit. Since the frame is rounded, the glasses cover your peripheral vision, allowing you to see clearly at all times. What’s more, these sunglasses come with a holder for your prescription lenses, which you can easily click onto the inside of the frame. Last but not least, the Sports Sunglasses Altalist Legacy 2 Photochromic come with hard and fabric cases and a microfiber cleaning cloth.
