The strength of the alpina lyron shield p is its large cylindrical panoramic lens. It ensures maximum visibility with modern style. This keeps you as safe as possible during sports while still looking good. Thanks to their polarising lens, the alpina lyron shield p sports glasses provide sharp contrasts. At the same time, glares are filtered out, creating the best visibility. Meanwhile, the mirroring reflects infrared rays and thus reduces strain on the eyes. The lenses provide 100% uv protection. Malleable nose pads as well as temples with a rubberised soft insert ensure the best possible comfort. Meanwhile, a high-quality folding mechanism keeps the strap in its position.
