What "cold" Knowledge Should You Know About Sunglasses
Nowadays, there are various types of sunglasses available on the market, but on the other hand, many people have found that some sunglasses feel particularly dim when worn, making it a bit difficult to see the road. Sometimes I feel eye pain, wear it for a long time, and even feel dizzy and dizzy. Obviously, the reason is that there is a problem with the quality of the glasses.
Firstly, let's talk about the real purpose of wearing sunglasses - of course not for a concave shape, but to prevent eye diseases!
1. The main function of sunglasses is to filter out ultraviolet rays. Excessive exposure to ultraviolet (UV) rays in sunlight can cause cataracts, eyelid skin cancer, and electric ophthalmic diseases. Even wearing a wide brimmed hat can only block about 50% of ultraviolet rays from reaching the eyes. Therefore, it is necessary to wear sunglasses when the sunlight is strong.
2. Sunglasses can filter short wavelength blue light. Research has found that long-term exposure to ultraviolet and short wavelength blue light is a risk factor for age-related age-related macular degeneration.
3. In summer, wearing sunglasses can reduce the regulatory burden on the ciliary muscles of the eyes under strong light, allowing the eyes to see objects comfortably in natural light.
Of course, sunglasses can play such an important role in protecting our eyes, and there is a crucial prerequisite - qualified quality.
