How to distinguish between good and bad sunglasses?
First of all, when buying sunglasses, first check the quality of the lens. Whether the lens surface is smooth, whether there are warping, wear marks, and bubbles. The warping of the lens will cause the line of sight to deviate, and the unevenness or traces and bubbles will cause dizziness and other discomfort. At the same time, the lens should not be too thin, otherwise high temperature deformation will also cause dizziness.
Secondly, when choosing sunglasses, you can take the sunglasses 45 cm away from the eyes, observe the vertical and horizontal lines around them through the glasses, such as window frames or door frames, etc., and then move the glasses up and down, such as linear distortion or swing, indicating that the lens is deformed , Should not be purchased.
Finally, pay attention to the color of the lens. There should be enough depth. Dark gray is better, dark brown and black are the next, blue and purple are the worst. These two lenses will transmit more ultraviolet rays, and yellow, orange and light red are not used as much as possible.
If you are buying online, it is best to choose a qualified online store. These online stores have strict control on the quality of the goods. Do not go to some informal shops or stalls for a short time to buy, because the impact of glasses on people is Recessive, when the problem is discovered, it is too late.
