Is UV Protection Enough for Children's Sunglasses?
From last year to this year, I have seen many group buying sunglasses on parent-child accounts, and I have found that most children's sunglasses overlook a very important issue, which is the lens polarization function.
If children's sunglasses use ordinary resin stained lenses, they only have the effect of preventing UVA and UVB. You should know that even the cheapest resin stained lenses can achieve 90% of the ability to filter ultraviolet rays. However, for the protection of children's eyes, it is also necessary to solve the problem of strong light and glare.
In the eyewear industry, adult professional sunglasses with slightly higher quality actually choose polarized lenses. Children's sunglasses may consider cost issues, and many brands still rely on the configuration of the most primitive resin dyed lenses. What kind of protective effect can polarized lenses bring to people's glasses?
A polarizer is a lens manufactured based on the principle of polarization of light, used to eliminate and filter scattered light in a beam of light, allowing light to enter the visual image of the eye on the right axis of transmission, making the field of view clear and natural. Therefore, polarizers can filter out many irregular light interferences and avoid the occurrence of glare, glare, and other phenomena.
When it comes to dazzling and dazzling, everyone must feel it. In sunny weather, the glass curtain wall is bright and dazzling, the strong reflection of car glass is dazzling. At night, car night lights make people temporarily blind, the water light on the seaside lake is dazzling, and the reflective points on the glass blackboard make people unable to read clearly. Even when reading under the night light, the copper coated paper is particularly smooth and reflective, which makes the eyes very tired. This widespread strong light and glare can cause greater irritation and damage to the human eye than ultraviolet radiation.
