Whether your sunglasses are polarized or not, we can't tell from the appearance of the sunglasses, but if we want to know whether there is a polarizing function, there is actually a way to detect it.
Non-polarized sunglasses only use the function of light reduction to reduce the intensity of glare and ultraviolet light, reduce the damage to the eyes, and cannot completely block these harmful lights.
Polarized sunglasses can completely block the glare caused by various factors such as scattering, refraction, and reflection because of their polarizing properties, and can also completely block ultraviolet rays that are harmful to human eyes. These stray lights are filtered out, and it is soft and comfortable to see things under strong sunlight.
