From last year to this year, I have seen many parent-child group buying sunglasses. Ruimin found that most children's sunglasses have ignored a very important issue, which is the function of lens polarization. If children's sunglasses use ordinary resin stained lenses, they only have the effect of preventing UVA and UVB. It is important to know that even the cheapest resin dyed lenses can achieve 90% of the ability to filter ultraviolet rays. However, the protection of children's eyes must also solve the problem of glare and glare. In the eyewear industry, in fact, adult professional sunglasses with a little bit of quality will choose polarized lenses. Children's sunglasses may take into account the cost issue. Many brands still stay at the most primitive resin stained sheet configuration. What kind of protection can polarized lenses bring to people's glasses? The polarizer is a lens manufactured according to the principle of light polarization. It is used to eliminate and filter the scattered light in the beam, so that the light can be input into the visual image of the eye on the transmission axis of the normal track, so that the visual field is clear and natural. Therefore, the polarizer can filter out a lot of irregular light interference and avoid the occurrence of dazzling and glare. Speaking of dazzling and dazzling, everyone must feel it. In the sunny weather, the glass curtain wall is dazzling, the strong reflection of the car glass is dazzling, the night light of the car makes people temporarily blind, and the water on the seaside lake is dazzling. , The reflective dots of the glass blackboard make people unable to read the words clearly. Even when reading a book under the night light, the coated paper is especially smooth and reflective, which makes the eyes very tired. This ubiquitous strong light and glare are more irritating and harmful to human eyes than ultraviolet rays. ?? Related reading: Children's sunglasses
