Pupil distance **Lens introduction:** 1.56 refractive index (generally ultra-thin) Taiwan safety lens, optical material with good light transmission and clarity. **Lens color:** Powder tea brown: (color depth 50%) The tea-brown lens can increase the ratio of yellow-brown light entering the eyes, and the ratio of blue light entering the eyes will be less. It can be said that it has a blue light filter function and improves visual contrast and clarity. In addition, the dark brown lenses can absorb the blue light scattered by moisture in the air and filter out short-wave blue light, which can enhance the contrast, see the details, and improve the visual contrast outdoors. Therefore, many athletes choose dark brown sunglasses, which are also used for driving sunglasses during the day. Good choice. https://c1.staticflickr.com/5/4848/45858987222_cf8d1a18f7_b.jpg **Frame size:** A 50mm B 22mm C 150mm D 132mm E 49mm **Note** 1.
