Faddy bifocal sunglasses match with brilliant ladies
The first thing that comes to mind when one thinks of sun protection is to protect skin, hardly think of protecting eyes. In fact, studies have shown that ultraviolet radiation will lead to keratitis, cataracts, retinal damage and other eye diseases. Thus, delicate eyes need our special care in heat summer days.
Please don't look up into the sun. Eyes are extremely weak. Short-term direct view to sunlight will result in an immediate shadow in eyes.Long-time direct view will lead to pain, tears, inflammation and blurred vision and so on, thus damage the retina.
It is well known that eyes are the most sensitive part to the ultraviolet radiation and they can widely absorb UV rays of different wavelengths. The 280nm ultraviolet radiation does maximum damage to the cornea and seems to cause conjunctivitis. The ultraviolet radiation with 290-400nm wavelength causes great damage to the lens, and it is also the cause 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 then what shall we do in daily life?
If you stay out in the sun, you'd better make use of hat, umbrella and bifical eyeglasses to protect your eyes from sunlight. It is worth to note that the progressive glasses you buy should be good enough in quality. 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 search results have proved that grey lenses are the best choice; lenses of too dark color may pass more UV rays to eyes. 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 eyewear too.You'd better not go outside at noon when the sun is strong and are likely to threat the security of skin and eyes.
