For most people, buying a pair of dark sunglasses in summer can play a role in UV protection and eye protection. In fact, such thinking is wrong. Eye experts pointed out that the effect of polarized sunglasses in summer is better than ordinary sunglasses.

Why are polarized sunglasses better than regular sunglasses? This starts with the characteristics of natural light. Natural lights, also known as unpolarized lights, are made up of electromagnetic waves that vibrate in specific directions. Therefore, after the polarizer filters the natural light, it can only pass in one direction. Polarized sunglasses are based on this characteristic of natural light to block harmful light.

No matter what the sun shines on, it will produce some harmful rays due to reflection or refraction. Polarized sunglasses can completely absorb these rays and reduce the damage to these rays to human eyes.

Ordinary sunglasses do not have this function. Its lenses cannot filter light, so it will only reduce the intensity of strong light and ultraviolet light, but it is powerless against harmful light. Therefore, ordinary sunglasses can only reduce eye damage. Even so, the biggest advantage of ordinary sunglasses is that they have popularity that polarized sunglasses do not have, so they are favored by many online spectacles.
