What does polarized sunglasses mean?_Sunglasses Knowledge_

Polarized sunglasses are the most commonly used sunglasses now, and many drivers, skiers, fishing enthusiasts, etc. will use polarized sunglasses. Many people who wear polarized sunglasses know that polarized sunglasses can eliminate cluttered light very well. So. What does polarized sunglasses mean? Let's take a look at it together. Polarized sunglasses are manufactured according to the principle of polarization of light. Polarized light, also known as polarized light, vibrates perpendicular to the direction of propagation. The function of the polarizer is that the light is adjusted to enter the same direction, and the eyes will feel very soft and not irritating when looking at the scene. Polarized light is conceived as a wave vibrating in one direction, while the vibrating wave of ordinary light is messy, and under the action of a polarizer, only the polarized wave vibrating in the same direction is allowed to pass. The polarizer can effectively filter the scattered light in the light book, and the field of vision is clearer and more natural. Some reflected light in life, such as the reflected light of the road, the reflected light of the building, the reflected light of the water surface, and the strong light of the lamp head will stimulate the eyes, affect the vision, and the eyes are easy to fatigue. Especially for some driving and some outdoor sports, it is very suitable to wear polarized sunglasses. The polarizing effect of sunglasses is inseparable from the polarizing layer in the lens, which can absorb the reflected glare perpendicular to the light transmission axis. Polarized sunglasses are made of multiple layers, as well as UV layers, which absorb UV rays. Impact-resistant layer, providing strong impact resistance and more.
