Why do children have to wear sunglasses from an early age?

Not to mention children, even adults can't insist on wearing sunglasses when going out. Not wearing sunglasses may be because you don't know how important it is. The main function of wearing sunglasses is to protect the eyes from or reduce the damage of ultraviolet rays, especially the damage to children's eyes! Ultraviolet rays can cause serious damage to the eyes, both transient and permanent. 80% of the population has been exposed to ultraviolet rays before the age of 18, so it is necessary to protect the eyes from an early age. According to foreign reports, only 5% of children wear sunglasses when they go out, and it may be lower in my country.

Which UV rays harm the eyes?

There are three types of ultraviolet (UV) rays, UVA, UVB and UVC.
  • UVA is not absorbed by the atmosphere and can reach the surface of the earth, so it is the biggest threat to the eyes.
  • UVB can be partially absorbed, but it can also damage the eyes. The eyes can get sunburned just like the skin when they are overexposed to the sun, among other problems.
  • UVC is completely absorbed and does not reach the Earth's surface. Therefore, the damage to the eyes is caused by UVA and UVB, and it is absolutely necessary to protect the eyes.

Why is UV light harmful?

Ultraviolet radiation will be absorbed by the cornea and lens of the eye, which will cause damage to the cornea and lens. UVA can also penetrate deeper into the eye and damage the fundus. Excessive short-term exposure to sunlight, UVB can cause "photokeratitis", which is a sunburn of the eyes. There will be red and swollen eyes, tearing, pain, sensitivity to light, and the feeling that there is a foreign body in the eyes. Long-term exposure to light can also cause cataracts or macular degeneration, both of which can cause blindness.

Why are children's eyes especially sensitive to UV light?

Our lens is a natural barrier against UV damage, and it has the function of filtering UV damage. But a child's lens is still maturing and doesn't filter as well as an adult's. So it is very important to wear sunglasses for children!

It may be difficult for children to take the initiative to wear sunglasses that they do not like. it. When choosing sunglasses, pay attention to whether they are UVA and UVB protection.
