2. The polarizing lens has a characteristic, that is, the lens is extremely light and thin. When distinguishing, you can compare the weight and texture with other ordinary sunglasses.

3. When you buy, stack two polarized lenses vertically, and the lenses 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. If there is a phenomenon of opacity, it proves to be a polarizer.

4. Place the lens and the LCD screen, such as the mobile phone display, in parallel and overlapping. Turn the polarizer. Looking at the LCD screen through the polarizer, you will find that the LCD screen will brighten and darken as the polarizer rotates.
