The color of the lens is made by adding color masterbatch or powder during injection molding, and the color directly affects the transmittance of the lens. In addition, the coating on the surface of the lens also affects the transmittance, because the main raw materials for coating are silicon dioxide and titanium dioxide, and it is known that the main component of sand is silicon dioxide. Coating on the forehead surface of the lens has two functions: first, to make the color more brilliant, Another function is to prevent UV rays.
We need to choose lenses with different light transmittance based on the lighting during skiing:
According to the transmittance of the lenses, we divide them into five ranges: S0 S1 S2 S3 S4, and choose lenses with different transmittance according to different weather conditions. For example, on cloudy days or at night, you should choose ski goggles with S0 or S1 transmittance. When there is plenty of sunlight, you should choose snow glasses such as S2 and S3.
The transparency of the lenses must be marked on the packaging of regular snow goggles, so when choosing, pay attention to the transparency. If the product can come with high transparency lenses as a gift, it is the best choice, so that skiing can be done 24/7. Ski goggles need to be easily replaceable to meet the needs of different lighting, and magnetic suction lenses have gradually become fashionable, making it easier to replace lenses with different light transmittance.
