Can clear lenses be polarized?
At present, there are no clear polarized lenses. A polarized lens is a thin film vertically arranged with silicon crystal coating placed inside the lens, just like a shutter, which covers the parallel light and only allows the vertical light to pass through. In this way, the glare from all directions can be eliminated, so it is clear and comfortable to wear. Transparent polyamide, the material of nylon lens, is a new variety of polyamide. The material of the nylon lens is mainly transparent polyamide. Due to the effect of the light filter, only light from a specific direction is allowed to pass through the lens, which filters the dazzling light from the sun on the water, land, or snow very well. It can not only make the landscape soft, clear, and natural but protect the eyes to a certain extent.
