Mention sun protection, most people think of skin protection, and rarely think of eye protection. In fact, studies have shown that ultraviolet radiation will lead to keratitis, cataracts, retinal damage and other eye diseases. Hence, for health sake, eyes deserve our special attention.
Never look sun straightly in the sunny days. Eyes are very fragile. If one looks at sun directly for a moment, he/she may be dizzy to watch. If one looks at sun directly for a long time, he/she is likely to get eye pain, tears, inflammation and blurred vision.
As is known to all, eyes are fragile and susceptible to ultraviolet radiation which would easily injury eyes. The 280-nm wavelength UV ray does the greatest injury to the cornea. It is likely to cause conjunctivitis.The UV ray of 290-400nm wavelength damages the lens badly, which is also the pathogenic factor of cataract.Research suggests that one more hour you bask in the sun every day; you are likely to get cataract with 10% more chance. And now we should talk about some precautions.
Wear hat or raise a parasol when you are outing. At the same time you can wear bifical eyeglasses which are also effective in protecting eyes from sunshine. It is worth notice that only quality bifical sunglasses are good to your eyes and effective in protection. Sunglasses of poor quality can't help in protection but result in injury to eyes. Buy a pair of anti-ultraviolet sunglasses when summer comes so that your eyes will be safer. Medical studies have certified that lenses in grey are best as grey have little influence on the effect of vision but effective in anti-UV. If you wear contact lenses, you can choose those with anti-UV function which can block 90% ultraviolet rays.If possible, you'd better wear progressive eyeglasses too.At noon, the sun is strongest and your skin and eyes are at highest risk. The best way to protect you is to keep indoors.
