Why you need to protect your eyes from the sun: damage to UV rays

The sun’s rays contribute not only to the production of vitamin D and a beautiful tan. The ozone layer of the atmosphere is getting thinner every year and the ultraviolet more and more aggressively acts on human skin, and also damages its eyesight. Therefore, with the onset of a warm and hot season and sometimes coming vacations, it is important to take care of your vision in order to keep your eyes healthy.
Can the sun damage the eyesight?
Long stay in the open sun without special sunglasses can eventually affect the vision: ultraviolet (UV) radiation can damage both the outer surface of the eyes and the internal structure of the organ. UV rays can provoke inflammation of the cornea of ​​the eye (photokeratitis), solar retinopathy, contribute to the development of dry eye syndrome and strengthen the existing one (this is especially important for people who spend a lot of time at the computer).

The eyes get tired of visible radiation, while we constantly “hang” in a laptop or smartphone, and then we go outside, and our eyes receive another portion of radiation – but already ultraviolet. The eyes of children and adolescents are more susceptible to the negative effect of sunlight; this is due to their anatomical features of the eyes. Also, children are more often under the open sun, and few parents acquire high-quality sunglasses for them.
Is it really that harm from the sun?
UV rays are an integral component of sunlight. The most dangerous for human health are UV rays with a shorter wavelength. Eye exposure to the sun is observed in the morning and in the morning, and the time from 12 to 16 hours is the period when the sun’s rays are most dangerous for the skin. Therefore, it is important to wear high-quality sunglasses in the morning and at lunch, and not just at noon or even going to the beach. Cloudy weather does not make UV rays less dangerous, because even on a cloudy day more than 90% of UV radiation enters through the clouds.
What to look for when buying points
Choosing sunglasses, it is important to purchase a quality product. To protect against UV rays, lenses have a special coating: glasses are labeled with an indication of the percentage of blocking UV rays of type A and B. It is also important in what area you live, because in the mountains, for example, the intensity of UV radiation is higher. There are also sunglasses for cloudy weather, for intense radiation (beach glasses), etc.

Therefore, to select such an important accessory should be entrusted to a specialist optics, and not a random seller on the street. Quality points must have appropriate permits. If you are a fan of chameleon glasses, the lenses of which change the degree of darkening at different intensities of light, then do not forget that such glasses must be changed frequently. Because the special coating that allows lenses to change their color, wears out quickly.
