The first thing that comes to mind when one thinks of sun protection is to protect skin, hardly think of protecting eyes. Instead, surveys show that ultraviolet radiation is the main cause of some eye diseases, such as keratitis, cataracts, retinal damage. So, we can't ignore the eye injury caused by ultraviolet radiation.
Don't look directly into the sun. Delicate eyes are easily hurt.Direct view to sun for a while may lead to temporary giddiness.One may suffer from pain, tears, inflammation and blurred vision if he/she looks up to sun for a long time.
As is known to all, eyes are fragile and susceptible to ultraviolet radiation which would easily injury eyes. The 280-nm wavelength UV ray does the greatest injury to the cornea. It is likely to cause conjunctivitis.The UV rays with the wavelength of 290-400nm are harmful to lens, which would result in cataract. Studies suggest one is more likely to get cataract if he/she roasts in the sun more. Then what should we do in preventing the harm?
If you stay out in the sun, you'd better make use of hat, umbrella and bifocal eyeglasses to protect your eyes from sunlight. It should be noted that you'd better buy a pair of bifocal sunglasses of good quality. Inferior sunglasses will hurt your eyes rather than protecting eyes. They may cause mydriasis. One must buy himself/herself a pair of sunglasses with anti-UV function. 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. People wearing contact lenses can buy UV-protective ones which are able to block 90% ultraviolet radiation. It would be safer to add a pair of progressive eyeglasses. You'd better not go outside at noon when the sun is strong and are likely to threat the security of skin and eyes.

As is well known, eye is a delicate tissue that is sensitive to UV rays. It can absorb UV rays with various wavelengths. The ultraviolet radiation with 280nm wavelength does the most damage to the cornea, and it is the cause of conjunctivitis. The 290-400nm wavelength UV ray can cause biggest damage to the lens, which is also the reason for cataract. Research suggests that one more hour you bask in the sun every day; you are likely to get cataract with 10% more chance. And now we should talk about some precautions.

As is known to all, eyes are fragile and susceptible to ultraviolet radiation which would easily injury eyes. 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.

It's best to avoiding going out at noon when the sun is very strong and much harmful to our skin and eyes.  

Speaking of sun protection in summer, everyone would pay attention to their skin, few remember eyes. Actually, some studies suggest that UV rays are really harmful to eyes and may cause keratitis, cataracts, retinal damage and so on. So, we can't ignore the eye injury caused by ultraviolet radiation.
Never look sun straightly in the sunny days. The eye is a delicate tissue. Short-time direct view to sun may result in transient giddiness. Long-term direct view to sunlight will cause pain, tears, inflammation and blurred vision and even hurt retina.
