What does the polarization of sunglasses mean?

The polarization of sunglasses refers to the technology of splitting light into two components with different vibration directions, and then removing one of them through a filter. Simply put, a polarizer is a filter that can block light in a certain direction. This technology can effectively block the horizontal or vertical light, thus reducing the burden on the eyes under strong light and the harm of ultraviolet rays to the eyes.

The polarizing technology of sunglasses makes people more comfortable when they are engaged in outdoor activities. Especially in summer, strong sunlight may cause visual fatigue, headache and other discomfort. Wearing polarized sunglasses can reduce this discomfort and create a clearer vision, which is very helpful for outdoor sports such as driving and water sports.

In addition, polarizers are also used in photography, electronic screens, glasses and so on. Through the application of polarization technology, the reflected light appearing on the screen can be reduced, and the works of photographers and painters can be protected, so as to be more truly presented to the public. In daily life, many people also use anti-blue glasses, which can effectively reduce the harm caused by electronic products to the naked eye. Therefore, it can be said that polarization technology not only facilitates our life, but also provides a reliable guarantee for our safety.
