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. For that reason, we ought to care our eyes especially in hot summer. Please don't look up into the sun. Eyes are very fragile. One may feel dizzy after looking up to sun for a short while. Direct view to sun for a long time may bring about damage to eye and retina, accompanied with pain, tears, inflammation and blurred vision.It is believed eyes are the most sensitive part to the UV rays; they can absorb a broad range of wavelengths of ultraviolet rays.The ultraviolet radiation with 280nm wavelength does the most damage to the cornea, and it is the cause of conjunctivitis. The 290-400nm ultraviolet radiation does damage to the lens and would result in cataract. Surveys show that if you bask yourself in the sun for one more hour every day, the rate that you get cataract increase 10%.So then what shall we do in daily life?Wear hat or raise a parasol when you are outing. At the same time you can wear ray ban glasses which are also effective in protecting eyes from sunshine. It should be noted that you'd better buy a pair of emporio armani glasses of good 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. It has been shown in much medical research that sunglasses of neutral density glass with grey lenses are best in blocking UV rays. It is better for contact lens wearers to buy anti-ultraviolet ones which cut 90% ultraviolet rays. If you wear boss glasses at the same time, so much the better. The sun is strongest at noon, which is harmful to both your skin and eyes. You'd better stay at home without going out.
