Fashionable bifocal sunglasses exclusively for brilliant girls
Generally speaking, people tend to associate sun protection with skin instead of eyes. Actually, some studies suggest that UV rays are really harmful to eyes and may cause keratitis, cataracts, retinal damage and so on. For that reason, we ought to care our eyes especially in hot summer.
Don't look directly into the sun. Eyes are very fragile. Short-time direct view to sun may result in transient 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 280nm ultraviolet radiation does maximum damage to the cornea and seems to cause conjunctivitis. The UV ray of 290-400nm wavelength damages the lens badly, which is also the pathogenic factor of cataract.Studies suggest one is more likely to get cataract if he/she roasts in the sun more. So then what shall we do in daily life?
When you go out in hot summer days, you must bring hat, parasol and bifical glasses with you for sun protection use. It is worth notice that only quality bifical sunglasses are good to your eyes and effective in protection. If you buy schlock sunglasses, instead of protecting eyes, you are doing harm to your 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.It will be better to wear a pair of progressive eyewear.The sun is strongest at noon, which is harmful to both your skin and eyes. You'd better stay at home without going out.
