With summer approaching, people know to go out with umbrellas and protective creams to cover their skin health, but UV rays also hurt the eyes, and the eyes need protection. UV rays from the outside of the eye into the inside, from the conjunctiva, cornea, lens, vitreous humor to the retina, can produce damage of varying sizes. The damage caused by UV rays to the eye is as follows: 1. Pterygium: It is generally believed that its occurrence is closely related to long-term UV radiation UVA and UVB, with a higher incidence in men than in women, and is commonly found in communities such as farmers and fishermen who are exposed to UV rays for long periods of time. 2. Keratitis: UVB can cause acute corneal epidermal pitting, usually within 6 hours of exposure to UVB or UVC. 3, cataracts: clouding of the lens, some studies have shown that an extra hour of sunlight per day may increase the likelihood of cataracts by 10%. 4, macular lesion: macular lesion is one of the main causes of vision loss in middle and old age, excessive ultraviolet light will cause damage to the macula. 5. Eyelid skin cancer: Prolonged excessive exposure to sunlight is likely to lead to eyelid skin cancer around the eyes. Preventing UV damage to the eyes has become an important task that we must do all year round. Start by avoiding UV exposure and avoiding going outside when UV intensity is strongest (10:00 a.m. to 2:00 p.m.). Also: Wear a hat with a wide brim and UV-protective sunglasses. Sunglasses gray and teal eye protection is best, buy sunglasses must go to a quality assurance optician to buy.
