[0002] Polarized lenses are lenses that only allow light of a certain polarization direction in natural light to pass through. Because of its light filtering effect, things will become darker when you wear it. In order to filter the glare of the sun shining in the same direction on the water, land or snow, special coatings in the vertical direction are added to the lenses, which are called polarized lenses.
