The difference between the two glasses

Non-polarized sunglasses only use the effect of dimming, which can only reduce the intensity of glare, ultraviolet light, etc., and cannot completely block these harmful rays. Polarized sunglasses can completely block the dazzling glare caused by various reasons such as scattering, refraction, and reflection. At the same time, it can completely block the ultraviolet light harmful to human eyes, and the identification of traffic lights by non-polarized sunglasses will cause huge color difference and become a hidden traffic hazard. The polarizer is based on the principle of polarized light, and the objects seen will not change color, ensuring safety.
