Are you ready to defend against the sunshine when going out? The World Health Organization has recently pointed out that ultraviolet radiation has become the culprit of skin cancers and cataracts since the destruction of the ozone layer. Doctor noted that only skin sunscreen is not enough. The eyes should also have sunscreen. Wearing broad-brimmed hat, to stretch the umbrella, wearing of anti-UV sunglasses or contact lenses are good tools for the eyes against the sun.

According to “Solar UV Index Practical Guide” issued by the World Health Organization, there are more than 2 million cataract cases caused by inappropriate long-term sun exposure. The harmful ultraviolet light wave is the killer of eye health. The long-term UV damage is related with the keratitis, retinal macular degeneration. At the same time it would affect the appearance of the eye and result in proliferation of fat as well as the damage of the eye retina.

Some eye doctors give some suggestion of eye protection in summer to those who want to enjoy in the summer. The first one is to not look directly at the sun. The eye is a very vulnerable organ. Looking directly at the sun when going out, the eyes are easy to be hurt even if you blind eyes. For a short time it may cause a temporary dark shadow in your eyes. For a long time apart from eye pain, tears, photophobia, redness and swelling and blurred vision, the light may even damage the retina.

The second instrument is to avoid engaging in outdoor activities under the hot sun at noon; the third measure is to wear broad-brimmed hat or parasol stays which is the most basic tricks sunscreen to avoid direct contact with the sun. The fourth instrument is wearing sun glasses; the fifth one to wear UV contact lenses.

Doctors also warn that not all dyed lenses are called sunglasses. Sunglasses should have a marked anti-UV. The coefficient of anti-UV must be over 400 which are enough to protect the eyes. You had better choose the light gray or green lenses. Sunglasses of poor quality can reduce the brightness of the sunshine but can not stop the light pollution. What is worse? It will make the pupil unprepared expansion in the lower luminosity state, on the contrary, the eye is more vulnerable.

As for the people who wear contact lenses may choose contact lenses with anti-ultraviolet function. According to the American National Standards, contact lenses whose lenses can filter out 95 percent of ultraviolet UVB and 70% of UVA can directly pack the most important pupil, and then wearing sun glasses means one more layer of protection.
