What does polarized sunglasses mean? A type of sunglasses (anti ultraviolet) that belongs to advanced sunglasses and can protect the eyes from harmful substances in sunlight. There are three common polarization methods, namely circular polarization, linear polarization, and elliptical polarization. polarized sunglasses use a method of linearly polarized light. Another term for linearly polarized light is planar polarized light, which causes light waves to vibrate along a specific orbit and exhibit a sinusoidal direction of motion.

The biggest function of polarized sunglasses is to effectively block ultraviolet rays from sunlight from entering the eyes. There are three types of sunlight: red ultraviolet rays and visible light, and ultraviolet rays cause significant damage to human tissues, especially to the skin and eyes. UVB, UVC, and UVA in ultraviolet rays can damage visual health, especially UVB, which can be absorbed in large amounts by the cornea, thereby damaging the eyes. Therefore, polarized sunglasses were invented to protect the eyes.

The manufacturing process of polarized sunglasses is more advanced. By combining three methods: reducing light intensity, absorbing harmful substances in ultraviolet rays, and reflecting partial light, the ultraviolet rays in the sunlight are blocked. Stronger polarized sunglasses can achieve a complete blocking effect, making the eyes harmless under strong sunlight, allowing them to see more clearly, and the effect is much better than ordinary sunglasses.
