Do you know that the eyes will be sunburned? Taiwan Cathay Hospital, Director of Ophthalmology Lin Si Yuan recently in a “contact lenses against ultraviolet rays” press conference to remind the eyes of the sun in addition to hats, umbrellas equipped with, sunglasses are also indispensable, but the glasses to cut off ultraviolet material for the first choice, modern shape or lens color black, not necessarily for the eyes of the sun. Since the hole in the ozone layer, the public exposure to ultraviolet light under the time and intensity are more early, ultraviolet damage to the eyes, divided into acute and chronic. Acute damage for instant exposure to very strong ultraviolet sunlight, such as snow or beach, this kind of damage is very strong, in three to six hours will damage the cornea, such as ultraviolet light directly burn the cornea, so that the cornea’s epidermal cells to produce the phenomenon of detachment, the patient will have pain, tearing and the eyes can not be opened, and other symptoms. Chronic damage is the cumulative exposure to UV-filled environments over the years, but do not take precautions, such as farmers and fishermen working in the field or at sea for a long time, may only wear a hat as a simple sunscreen, and over time there will be chronic changes such as cataracts, the crystal body will absorb UV rays to become more cloudy, and easy to winged flab. The best way to fight UV is still “block”, umbrellas, hats and other basic sunscreen equipment, sunglasses is indeed a good way to protect the eyes from the sun, but to choose the material has the function of blocking ultraviolet sunglasses are effective. Some people mistakenly think that the darker the color of the lens, the more you can block ultraviolet rays, but this type of lens may only be able to block visible light, the public misunderstanding but jeopardize the maintenance of the eyes. Lin Siyuan also mentioned a case of strong sunburn in the clinic, there is a child because the naked eye directly watching the phenomenon of solar eclipse, because it is a concentrated and very strong ultraviolet radiation damage, macular burning white spots. As for general sunburns, it is not uncommon to hear of sunburns in the sun that result in broken skin.
