Modern style sport glasses with lightweight frame and special Interchangeable polycarbonate photochromic lenses with reading area, that are designed for people with far sighted vision. These lenses have a light transmission of 85-17%. The brighter the light, the darker the lens automatically becomes. One lens provides you with category 1, 2 and 3 levels of eye protection.
Grilamid Frame Material
BBB sports glasses frames are made of Grilamid TR90. This is a light and flexible material, providing great durability and a level of comfort. Grilamid has some exceptional characteristics which include high heat distortion temperature, good flexural bending strength and high stress crack resistance. This makes Grilamid an ideal material for BBB´s sport glasses frames. You can bend your frame to place your lenses, without wondering if the frame is going to crack or not.
PH Lenses – Photochromic
Automatically adapts to changing light conditions. They turn dark when it’s bright and become virtually clear in low light conditions. Especially the available light range is unique. BBB’s lenses can adapt from allowing 85% - 17% of the available light to flow through.
