Stylish progressive glasses specially for good-looking women
Generally speaking, people tend to associate sun protection with skin instead of eyes. Instead, surveys show that ultraviolet radiation is the main cause of some eye diseases, such as keratitis, cataracts, retinal damage. Hence, for health sake, eyes deserve our special attention.
Don’t look directly into the sun. Eyes are very fragile. If one looks at sun directly for a moment, he/she may be dizzy to watch. Long-time direct view will lead to pain, tears, inflammation and blurred vision and so on, thus damage the retina.
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.Some studies have shown that if people expose to the sunlight for one more hour every day, the risk of cataracts will rises by 10%.So what can we do to prevent the injury?
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. What is noteworthy is that the quality of bifical sunglasses is very important to the health of eyes. Inferior sunglasses will hurt your eyes rather than protecting eyes. They may cause mydriasis. It is necessary for you to have a pair of sunglasses with a special coating that locks UV light in summer. 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. People wearing contact lenses can buy UV-protective ones which are able to block 90% ultraviolet radiation. It will be better to wear a pair of progressive eyewear.Don’t work or do activities outside at noon because the sum at that time is strongest and prone to hurt skin as well as eyes.
