The first thing that comes to mind when one thinks of sun protection is to protect skin, hardly think of protecting eyes. In practice, researches indicate that eyes exposure to ultraviolet radiation will do injury and even cause diseases to eyes. Thus, delicate eyes need our special care in heat summer days.
Don’t look directly into the sun. Eyes are extremely weak. Direct view to sun for a while may lead to temporary giddiness.Long-time direct view will lead to pain, tears, inflammation and blurred vision and so on, thus damage the retina.
As everyone knows, eyes are sensitive to bright sunlight and can absorb ultraviolet radiation of any kinds. The UV rays with the wavelength of 280nm are most harmful to the cornea, which would result in 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%.And now we should talk about some precautions.
If you stay out in the sun, you’d better make use of hat, umbrella and Swarovski crystal beads to protect your eyes from sunlight. It is worth to note that the swarovski beads you buy should be good enough in quality. Poor sunglasses are not helpful in protecting your eyes; instead, they may cause a lot of problems to eyes. One must buy himself/herself a pair of sunglasses with anti-UV function. Medical study has turned out that it is wrong that the darker the better in terms of lenses. Grey is a preferential choice. People wearing contact lenses can buy UV-protective ones which are able to block 90% ultraviolet radiation. In the meantime,Eureka crystal beads will be at the Marlborough Innovative Beads Expo May 6th to May 8th.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.
