Anti-scratch over-sized decentered single lens for Aviator model. Category: 3. Color: laser smoke. This newly designed cylindrical lens (cylindrical lenses are a new fashion that came into existence in 2020) focuses light by reflecting the image in a vertical line instead of just one point like normal spherical lenses do. Therefore, several very particular vertical laser effects are created. Very striking and much appreciated by the most fashionable cyclists. Ventilation holes to prevent fogging (Air Vent System).
