Sunglasses made of glass material have extremely high light transmittance, allowing light to pass through the lens to the maximum extent possible making the scenery seen by the wearer clear and realistic. The color reproduction is high and the original color can be preserved to the greatest Polarized sunglasses use special polarizing lenses that can selectively filter light from specific directions, just like the principle of blinds, filtering out scattered glare such as reflected light and scattered light, allowing only light from specific directions to pass through The surface hardness of glass material is extremely high, 2-4 times that of other materials' lenses. It has superior scratch resistance and is not easily scratched by sharp objects in daily use. It can effectively maintain the smoothness of the lens surface and extend the service life of sunglasses. By strengthening techniques such as heating or chemical treatment, the impact resistance of glass lenses is significantly improved, meeting the CEN lens strength standards and FDA steel ball free fall impact lens experimental standards Polarized lenses filter harmful light while maintaining high transmittance, allowing enough visible light to pass through the lens, making the scenery you see clear and realistic, with high color reproduction, and maximizing the preservation of original colors, presenting you with a clear and.syi
