Every year put over 100 new items to the global market.Polarized Advantage Improves visual comfortImproves contrast and visual clarityReduces eyestrainAllows for true perception of colors Reduces reflections and eliminates glareHow Polarization Works The sun's rays reflect light in every direction, so when a ray hits a flat surface, the reflected light shines back at your eye and is magnified, causing glare. Glare is a real buzzkill. It reduces your depth perception, distorts your view and color perception, and can even temporarily blind you. Not cool.Regular sunglassesare designed to only reduce the amount of light that is transmitted through the lens horizontally and vertically. But the chemical filter on the lenses of polarized sunglasses is designed to absorb horizontal light waves, while still allowing vertical waves to pass through. Because light only travels in one direction through polarized lenses, glare is eliminated.Drag the arrow from left to right to see the effects of polarization."TIPPS:How to place sunglasses:Please put sunglasses convex facing up, otherwise it will scratch the lens.
