Protect your eyes from UV rays

Speaking of ultraviolet summer, I think that is normal Speaking UV tanning, may not forget. The impact of eye.

UV light is bad for your eyes

Ultraviolet sun rays of the surface of what the underlying problem is the long wavelength waves A, B are short-wavelength waves. A wave is to promote black skin aging and skin color, B is the wave nature of sore red tan mal. Affects both bad for living, and that the magnitude of harm to the eye than the A wave becomes a problem is more of a B wave. Highly reflective to ultraviolet, which can rest assured that just because there is no shade. The reflection and scattering of light from the ground and remember that which had been often a large amount of UV-knowledge.

Eye disease caused by ultraviolet

If the eyes are exposed to strong ultraviolet light, redness, bringing the first hour of short, more "keratitis" and "snow eye" (a state that has tan eyes. A small scratch on the surface of the cornea, tan 6 After about 12 hours - from strong pain, redness in the white of the eye, and cause a feeling of gritty. to heal a few days rest is required. snow blindness.) and I get an acute disorder. Turbidity that lens is exposed over the long term UV and so-called "cataract" or it covers the iris to form a triangular portion of white "pterygium" (or low vision or become astigmatism and progress) Chronic said You take care of you.

On top of that chronic diseases take time to progress without spending will realize that UV causes a lot of people also going to decline with age. No data yet that can get sick or how much it basks in particular ultraviolet light is probably one of the reasons often neglected measures to ultraviolet eyes. However, over 50 "pterygium" On the number of patients, 07% in rural areas in Ishikawa strong ultraviolet Amami whereas 27% can be seen up to serious long-term exposure to ultraviolet eyes it is obvious damage.

UV radiation to the eyes and time

To protect your eyes from ultraviolet rays, is often thought to simply be careful with the sun, you may be aware of us. It is the strength and amount of UV entering the eye is that the sun is not proportional. In other words, when the sun's gaze, the most dazzling morning or evening, that is, the culmination of the sun at noon sunlight enters the eye is that. That's right indeed.

Normal human vision is 45 degrees from 40 degrees up from horizontal, more if the sun on it and not feel bright. , The first anti-ultraviolet radiation in the morning which should, and I do not have to say if the sun is 45 degrees, this is totally incorrect. Culmination of the sun at high altitude by the time the ultraviolet light scattering and reflection is seen coming in from every direction. After all, the season becomes stronger UV, but when you go out will be noon the morning, and said ultraviolet light is always advisable to take measures.

Protect eyes from UV rays

As seen above, which measures the UV light is bright and feels a lot slower. Effects of ultraviolet radiation to the eyes, the longer will appear over time. I think that's where they do not like cataracts. Vision is very important. Much better measures of the 20s just starting. Few Japanese people I wear sunglasses to protect your eyes means for effective UV protection sunglasses we use. Anyone who normally wear spectacles, and use of effective UV protection lenses. Contact is exactly so. And broad-brimmed hat and UV-cut umbrella , such as fully equipped with burns relentlessly, is very important to prepare for the diffuse UV light.
