Exposure to UV rays Dangers Of Eye

Tuesday, August 2, 2011

Did you know that the sun emits UV rays can be harmful to your eyes? UV rays are categorized into 3 groups
namely

UV C rays with a wavelength of 200-280 nanometer. Energy levels of UV radiation on this type is the most dangerous. UV-C rays from the sun mostly been absorbed by the ozone layer in Atmospher (Stratosphere). UV-C light is also produced by welding so that when performing this activity must use the correct protective.

UV B rays with a wave length of 280-315 nanometer. Energy levels at most cause damage to the body (skin looks red and sore) and eye (keratitis: Inflammation of the cornea with the pain was - and it usually causes severe visual impairment)

UV A rays with a wavelength of 315 Nanometer -380. With the level of the lowest-energy radiation are potentially harmful to the eyes if exposed in the long run such as cataracts. You should use a sunglass to protect the eyes if too often baraktifitas under the sun.
