Faddish progressive glasses for spandy lady
Saturday, August 1st, 2009Mention sun protection, most people think of skin protection, and rarely think of eye protection. As a matter of fact, researches show that eyes are sensitive to UV rays which would do harm to eyes and cause eyes diseases. Therefore, we should pay attention to eye protection from sunshine.
Don’t look directly into the sun. Delicate eyes are easily hurt.One may feel dizzy after looking up to sun for a short while. 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 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 a set of hat or employ a parasol when you go outside. Meanwhile you can wear a pair of bifical glasses which prevents direct sunlight to eyes. 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. Prepare a pair of UV-cut sunglasses for summer use, and you will benefit a lot. Medical search results have proved that grey lenses are the best choice; lenses of too dark color may pass more UV rays to eyes. Those who wear contact lenses can also choose those with anti-VU code which can block 90% UV rays. It would be safer to add 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.
