Perfect for when the weather changes and the courts move to a indoor or covered setting. A photochromic sun lens is a light sensitive lens which reacts to UV exposure and visible light to adapt its transparency according to the ambient light. With an initial medium tint (cat 0) in shadow, the photochromic sun lens reacts to light on a bright sunny day and darkens (to cat 4). This large photochromic shift makes it a sun lens for all seasons or weathers. On a cloudy day, in a tunnel or shadow, a pair of sunglasses with photochromic lenses stays clear and always gives the wearer the right light intensity for clear vision all day long.
