oakley sunglasses all models, What is UV radiation or ultraviolet (UV for short) light is electromagnetic radiation which of the sun comes with a shorter wavelength than that of visible blue or violet light. The UV radiation is usually associated with Sun Fire, premature aging of the skin, and other harmful health hazards such as skin diseases and cataracten, oakley sunglasses all models.

oakley sunglasses all models, We would have to consider ourselves fortunate, because our planet through an ozone layer is protected and which our inhabitants of a large quantity of UV radiation protection, But the ozone layer can not all UV radiation coming in block and a small amount of UV radiation calls yet by the atmosphere of the earth, This is now even more become reality, because, as we all probably know, the ozone layer of the Earth has become thinner and thinner in the course of the years and it has already had a hole in a part. The ultraviolet radiation is classified in three groups . These are UVA and UVB and UVC. UVA-radiation has the longest wavelength of the three and can not by the ozone layer are absorbed. It goes through the ozone layer and a part of the cause of the above mentioned health hazards. It is also said that the Radicals are liberated and skin diseases such as melanoma caused. Although there is no report has been suggested, for that the UVA rays largely through the lens of the human eye to be absorbed. The UVB radiation has a medium wave length by the ozone layer is absorbed, although a small quantity is still able to penetrate. The UVB rays can damage the eyes potential and are responsible for sunburn, elevated melanin production and some types of skin cancer. Although no conclusions have been created, by a lot of scientists and researchers claimed that the daily exposure to UVB rays cataracten in your view can cause. In contrast to the two previous, demands the radiation brugmann uh not much attention and is not a lot to make you press, since it is entirely by the ozone layer is absorbed. No amount of radiation brugmann uh, the atmosphere of the earth. Although this is the case and although it was the shortest wave length, is the most dangerous UVC and has the most of the potential damage of all three groups. The amount of UV radiation that reaches the Earth varies, it depends on several factors: the time of day (the highest values of UV radiation for during the afternoon when the sun is at its highest and strongest point is); time of the year (the highest values for during the summer time); width position on the earth (the highest values of UV radiation are located on the equatorial area, because the sun rises the most located near); altitude on the earth (the value increases with the height, because the atmosphere uitdunt if the further away from the sea level); weather conditions (cloudy weather or dark heavens can help to reduce UV values); and reflections (some areas may reflect UV radiation, even if you are in The shade can you still reach.) The UV radiation values are measured by means of a global standard, called the Ultraviolet Index or departments.
