But the color of the lens depends on the concept of transmittance, which is the ratio of the luminous flux passing through the lens to the incident luminous flux. The UV protection ability of the lens is closely related to the transmission ratio. The lower the UV transmission ratio, the stronger the ability to block the front UV. So choosing sunglasses is not the fact that the darker the lens color, the better. On the other hand, wearing glasses of lenses that are too dark on the wrong occasions can be dangerous. For example, when driving in summer, the sunlight is very strong, and wearing dark sunglasses when driving is easy to filter out light-colored objects, affecting the judgment of the distance between cars. In an emergency, dark sunglasses will delay the speed of image analysis of the optic nerve, resulting in slow response, and thus causing dangerous situations.
