Yesterday was the 21st national eye-loving day. The theme of this year's love-eye day is to protect the eyes and start small. To prevent or delay the development of myopia, the public knows that they should go to outdoor activities and look far away. However, experts said that outdoor activities must also be based on the law to ensure the health of the eyes.
In outdoor activities, the biggest cause of eye damage is ultraviolet radiation. Hong Peihua, chief physician of Nanan City Hospital's five subjects, said that the eyes are as vulnerable to sunlight as the skin. The corneal tissue absorbs UV light and chemical reactions occur. It is prone to dryness, severe pain, tearing, and conjunctival hyperemia. If the long-term ultraviolet radiation will increase the risk of suffering from senile cataract, but the more potential long-term effects are age-related macular degeneration; and other eye tissues may also suffer from some complications after ultraviolet radiation, such as eyelid skin cancer, palpebral fissure, etc. These eye diseases can cause eye discomfort or appearance to be affected, and can even lead to blindness. The hazards of UV rays to the eye structure are cumulative.
So, how to avoid the damage of ultraviolet rays to the eyes? Experts suggest that the best way is to wear sunglasses or polarizers with UV protection function, you can also wear a photochromic mirror with antireflection film. In outdoor sports, eye protection is particularly important. Among them, the protection of the ball sport should pay more attention to it. The first is to avoid eye injury caused by the impact of the ball, and then to pay attention to the protection of ultraviolet rays.
Even if sunglasses protect the eyes, they should avoid outdoor use for a long time, especially between 10am and 3:30pm every day, because ultraviolet radiation is the strongest during this period and excessive solar radiation should be avoided. Hong Peihua reminded.
