Polarized is made according to the principle of polarization of light. We know that when sunlight is projected on the surface of the road or water, it directly stimulates the eyes and makes them feel dazzled, tired and unable to sustain vision. Especially when you are driving a car and doing outdoor recreational activities, it not only affects our work and entertainment mood, but also affects our judgment of objects and causes danger. Long-term exposure to direct sunlight can also lead to rapid decline of vision, forming myopia, hyperopia, astigmatism or cataract. The special effect of polarizing mirror is to eliminate and filter the scattered light effectively. The light can be put into the visual image of the eyes on the light transmission axis of the normal orbit, so that the visual field is clear and natural. Just like the principle of blinds, the light is adjusted into the same direction to enter the room, naturally making the scenery look soft and not dazzling.
