Two ways to identify sunglasses

1. See the product identification


Pay attention to whether the glasses are marked with anti-UV function and anti-shock function. Because not all sunglasses can protect against UV rays. If there is a "UV-proof" function, there should be "100% UV protection" and "UV400" on the front of the product label or glasses.


If it is a "anti-shock" function, it should have "attack performance", "pass the US FDA certification", "conform to the highest standards in Europe and America" on the label or the manual. At the same time, these logos or instructions should be kept in good condition, in case there is a problem.


In particular, myopia children equipped with myopic sunglasses. It is recommended to fit myopia sunglasses with impact resistance to prevent unnecessary accidents in children.


2. Observe the quality of the lens


When the sunglasses are placed in front of the eyes, look at the distance through the lens, move the glasses up and down, left and right, the target should not swing, the lens color is stable. Looking through the lens, the color of the surrounding things is not distorted, and has the ability to recognize different color signal lights.


The color of the sunglasses is not very helpful in resisting ultraviolet rays. In addition to pursuing the beauty, the sunglasses should be carefully recognized, and the sunglasses should be protected from ultraviolet rays and glare, which can reduce the bright and harmful ultraviolet rays (UV) Light and glare damage to the eyes. Polarized lenses, anti-reflective lenses, etc. can make sunglasses better reduce glare, anti-reflection, increase object contrast in foggy and cloudy days, and make the field of vision clear.
