We extend the appearance of the traditional Japanese Tengu glasses into polarized front-mounted sunglasses clip-on. The base is a titanium 40mm perfect round frame, which can be used as daily optical wear. The Tengu-shaped clip-on is equipped with polarized lenses. The lens is put on the frame with a four-claw hook method. It has both practical and styling functions, and the overall weight is not too heavy. This model is available in four colors.
