How to distinguish polarizer

u003cbru003eThe appearance of glare can cause discomfort and fatigue to the eyes and affect the clarity of vision. Polarizers are sunglasses that can effectively filter out glare. Nowadays, UV-resistant glasses are usually divided into two types: sunglasses (sunglasses) and polarized lenses. Sunglasses are commonly known colored glasses used to block sunlight and ultraviolet rays. But in our daily life, in addition to sunlight and ultraviolet rays, when light passes through uneven roads, water surfaces and other places, irregular diffuse reflection light will be generated, commonly known as 'glare'. At the beginning, the effect of wearing a polarized lens is compared with that of not wearing it (the one on the left is worn). There are many ways to distinguish the polarized lens. One of the simpler is: stacking two polarized lenses vertically, the lens will appear opaque . The reason is that the special design of the polarizer lens only allows parallel light to pass through the lens, and most of the light is blocked when the two lenses are stacked vertically. When you buy, you can immediately know the authenticity and quality of the product with such a simple operation. At the same time, there is usually an identification board for distinguishing the polarizer. It looks like there are no black stripes to the naked eye, but you can see the black streaks that you don’t see with the naked eye when you wear the polarizer. The sunglasses are gone.
