For many people, sunglasses are one of the indispensable tools in summer. Whether it's going for a beach swim or an outdoor outing, wearing a pair of handsome sunglasses will make your whole person more fashionable. Now, many big brand sunglasses will highlight their polarized characteristics when they are promoting their products, and polarized sunglasses seem to be well-known as a unique selling point of products. So what is the difference between polarized and unpolarized sunglasses? How to determine if sunglasses are polarized? Gogogo, let's continue reading together!

The difference between polarized and unpolarized sunglasses. Even though many sunglasses brands have launched polarized sunglasses, there are still many friends who are foolish enough to distinguish between polarized and unpolarized sunglasses! So, do you know the difference between polarized and unpolarized sunglasses?

Nonpolarized sunglasses generally only have two basic functions: blocking strong light and filtering ultraviolet rays, and their efficiency in filtering ultraviolet rays is relatively low. But do you know that in our daily lives, in addition to strong light and ultraviolet rays, light passing through uneven roads, water surfaces, and other places can also generate irregular diffuse reflection light, which can cause blurred vision and fatigue in the human eye?

Polarized sunglasses can filter out this type of light and only absorb the reflected light from the object itself, presenting the object realistically, making the field of view clearer, and reducing visual fatigue. In addition, polarized sunglasses, due to their efficient filtering layer, have a blocking rate of 99% against ultraviolet rays, which can effectively reduce the harm of ultraviolet rays to the eyes.
