What is the difference between polarized sunglasses and ordinary sunglasses?

u003cbru003eSunglasses are no longer just to block the sun, but have begun to become a fashion. People have used sunglasses as a small prop to enhance charm. Sunglasses generally have two kinds of ordinary sunshade and polarized light. So what is the difference between polarized sunglasses and ordinary sunglasses? Recommended reading: What color sunglasses is better for driving? YC9703 Ms. YC9703 Sunglasses, the editor below will talk about the difference between the two. First, let's talk about ordinary sunglasses, which generally refer to sunglasses that only have the two basic functions of blocking strong light and filtering ultraviolet rays. Such sunglasses have a single function, lower technical content, and lower production costs. In terms of polarized sunglasses, the biggest difference between polarized sunglasses and ordinary sunglasses is the treatment of reflected light. In the environment in which we live, there are three types of light, direct light, reflected light and diffuse light. Diffuse light is not usually perceivable, but it is the most important kind of light that our eyes can see. Since direct light has a fixed light source, as long as a little attention is paid, it will not cause harm to our lives. These common reflectors in life often reflect light suddenly, which will bring a lot of inconvenience to our lives. For example, for a driver who is driving, the front rearview mirror is an uncertain reflected light source. Water on the roadside or smooth flat objects carried by passers-by can become the reflected light source. These reflected lights may cause trouble or even trouble to the driver's driving. It is dangerous. Polarized sunglasses are aimed at the reflected glare and can filter it out, so that it can prevent vertigo, and it will make the field of vision clearer and reduce visual fatigue when traveling in summer. Finally, it is recommended that you choose polarized sunglasses when you choose. For the sake of health, the advantages of polarized sunglasses are still relatively large. Of course, I don't reject ordinary sunglasses. Friends who like high fashion can still choose. It depends on the purpose of sunglasses. Related Reading: Sunglasses and Sunglasses
