As we all know, long-term ultraviolet radiation can cause skin changes, such as skin erythema, skin burns, pigmentation, and even skin cancer. Chongqing's summer has always been famous all over the country.
Although it should be sunscreen all year round, it seems that only in the summer, in order not to be tanned, everyone will really take sunscreen as one thing. But you know what?
Ultraviolet radiation can also cause damage to eyes, and in serious cases it can also cause blindness. So, what should I do with eye sun protection in summer?
As National Eye Care Day arrives on June 6, we might as well learn about it.
The eyes are very injured without sun protection in the hot sun. The eyes are the most direct part of receiving ultraviolet rays in the sun. The eyes do not pay attention to eye protection in the hot sun, which is easy to cause cataract, fundus damage and other diseases.
In the article 'Ultraviolet radiation and human health' published by the World Health Organization, the harm of ultraviolet rays to eyes was released.
The article points out that about 18 million people in the world are blind due to cataracts, 5% of which may be caused by ultraviolet radiation. And ultraviolet rays can also cause other serious eye diseases--
Keratitis, retinal destruction, macular degeneration, snow blindness, etc. So, how should the eyes be sunscreen in summer?
Reducing sun exposure and proper eye protection are the two principles to avoid UV damage to the eyes.
It is worth noting that from eleven o'clock A. M. to fourteen o'clock P. M. , direct sunlight has the strongest amount of ultraviolet radiation and causes greater damage to eyes, especially sun protection. It can be used to protect the sun from the sun.
In daily life, in addition to applying sunscreen and umbrellas, concave-shaped fashion sunglasses have become the first choice for most people.
Inferior sunglasses not only do not protect against UV rays, but also cause damage to the eyes.
So, what are the precautions when buying sunglasses?
1, do not buy at will, should go to the formal glasses organization (Hospital or regular glasses shop)
Buy sunglasses with UV protection produced by regular manufacturers.
- Don't use colored glasses as sunglasses.
Because this kind of glasses does not have the function of isolating ultraviolet rays, after wearing them, the eyes are equal to the wide opening of the door, allowing ultraviolet rays to invade, and the damage to the eyes can be imagined. 3, wearing time should not be too long.
After wearing sunglasses, the visible light entering the eye decreases, and the pupil will naturally enlarge, resulting in narrow anterior chamber angle.
Over time, it is easy to induce acute attack of angle-closure glaucoma. Patients may also suffer from red eye, eye pain, headache, sharp decline in vision, and even accompanied by nausea, vomiting and other symptoms.
4, in addition to the style and price, it is also important to choose the face type and distance when buying sunglasses.
Because sunglasses are too large and too small, they may cause eye discomfort after wearing.
5, sunglasses color depth to medium is better, brown, gray, green is the first choice.
Because the color is too light, the function of resisting strong light will be weakened, and it will still feel dazzling discomfort when it comes to outdoor activities with sufficient sunlight;
The color is too deep, it will affect the visual object, and even cause the color of the thing to be distorted.
- Children under the age of six should not wear sunglasses.
Because children's visual function has not yet developed to normal level, wearing sunglasses for a long time may affect visual development and even lead to or aggravate amblyopia.
Moreover, children may suffer eyeballs or faces from eyeballs after falling due to poor self-control or incomplete motor coordination.
