LifeTimes once published an article titled “99% of people don’t know, the eyes have 15 secrets”. The article said that if the eyes are exposed to sunlight for a long time, the tissue inside the eyeball will thicken, which can only be done surgery to restore it.

Long-term exposure to the ultraviolet rays of the sun is also prone to cause eye complications, such as conjunctiva, cornea, lens and retina, and structural changes. resulting in permanent damage to visual function. Therefore, on a sunny day, choosing to wear a pair of sunglasses should not be for being handsome, but a choice to protect your eyes.

The biggest “must” is that the glasses must meet the national industry standard requirements for sunglasses. For example, sunglasses with the “CE” mark mean that they meet European safety standards, and each pair of domestically produced glasses must be marked with the implementation of the standard number, proving that they are qualified products.

In the dazzling consumer market for sunglasses, the lenses of some inferior sunglasses are likely to be made of plastic. The cost of plastic is very low, not only does it not protect against ultraviolet rays, but the light transmission effect is also very poor.

Sunglasses are very important for visual health. Therefore, it is best to buy it under the advice of an ophthalmologist and optometrist.

It’s also important to note that when shopping for sunglasses, customers should choose different filters based on their daily activities and geographic location. “Chongqing Morning News” once introduced that sunglasses can be divided into light-colored sunglasses, sunshade mirrors, and special-purpose sunglasses, which can be divided into categories 1, 2, 3, and 4 according to the visible light transmittance. For example, when choosing sunglasses for children, experts recommend that parents choose light-colored sunglasses, or sunglasses with light transmittance classified as 1, 2, and 3.

Adults who have been driving for a long time need to use different types of filters according to the different terrains they often pass through when choosing sunglasses. For example, some high-level filters may interfere with the driver's recognition of traffic signs. In general summer, medium-grade sunglasses are sufficient; however, if you are outdoors, you need to wear sunglasses with stronger light reflection and the highest protection level to protect your eyes.

Just as price isn’t the only measure of quality, darker lenses don’t necessarily mean better eye protection from sunglasses. Dark lenses that do not properly filter UV rays can also cause pupil dilation and increase the probability of radiation entering the eye, thereby increasing damage to the tissues in the eye.

If the eyes are exposed to ultraviolet radiation for a long time, in some cases retinal photoreceptors (rod cells and cone cells) will have problems, vision will gradually decline, and the macula will degenerate; more seriously, it may cause the degenerated conjunctival tissue to invade the cornea, commonly known as "the surfer’s eye"
