Glases bifocals are very good for correcting presbyopia. To know more information about such glasses please read on.

As is well known, eye is a delicate tissue that is sensitive to UV rays. It can absorb UV rays with various wavelengths. 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.Research indicates the risk to suffer from cataract rises by 10% if one more hour every day people expose to the sun. Well then, I’d like to tell you some preventive measures.

The first thing that comes to mind when one thinks of sun protection is to protect skin, hardly think of protecting eyes. Actually, some studies suggest that UV rays are really harmful to eyes and may cause keratitis, cataracts, retinal damage and so on. Hence, for health sake, eyes deserve our special attention.

Don’t look directly to the sunlight in the hot sunny days.Delicate eyes are easily hurt.If one looks at sun directly for a moment, he/she may be dizzy to watch. Long-term direct view to sunlight will cause pain, tears, inflammation and blurred vision and even hurt retina.

When you are outgoing in summer, remember to wear broad-brimmed hat or use umbrella, a pair bifocal glasses is most effective in protecting your eyes. It is worth to note that the bifocal sunglasses you buy should be good enough in quality. Inferior sunglasses will hurt your eyes rather than protecting eyes. They may cause mydriasis. Buy a pair of anti-ultraviolet sunglasses when summer comes so that your eyes will be safer. Medical study has turned out that it is wrong that the darker the better in terms of lenses. Grey is a preferential choice. If you wear contact lenses, you can choose those with anti-UV function which can block 90% ultraviolet rays.Your eyes will be safer if you add a pair of progressive eyeglasses. 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.

There are more and more glases bifocales on the market now. For female, it’s very important to choose a great pair of such glasses.
