Are sunglasses as a sun protection tool afraid of exposure?
I believe that many people have heard that it is best not to put sunglasses on the car in the summer, it will be very dangerous. When placing sunglasses, remember not to put them in the car. Why do you say that? Do you know it?
Because some people put their newly bought sunglasses on the driver's seat and were damaged by the hot sun: Cracks on the mirror surface, or even peeling of the mirror film, many people think it is a problem with the quality of the glasses, even the big-name sunglasses , The same problem also appeared when they put it in the car. In fact, it is not. In the hot summer, if the door is closed, the temperature inside the car can be as high as 60℃. Under the windshield inside the car, the temperature is very high like a sauna. Under such an environment, the lens is prone to surface turtles. Cracks and stripes appear like water lines. In severe cases, it may cause deformation, lens film shedding, etc., which has nothing to do with the quality of the glasses. "After the lens is exposed to the sun, you will find that the sunglasses have different degrees of damage”. So everyone must not put the sunglasses in the car. Although the sunglasses are to block the sun, they are also afraid of the sun. Haha
That is to say, after the sunglasses are exposed to high temperature, the frame will be severely deformed and distorted. Some lenses of poor quality will lose their sun-shading function when the film is damaged after high temperature. Therefore, in order to avoid the sun-burning problem of sun protection tool-sunglasses, it is best to wrap unused sunglasses and store them in a dark, dark place.
