Electromagnetic radiation and health of exposure. Ultraviolet light, specifically UV-B, has been shown to cause cataracts and there is some evidence that sunglasses worn at an early age can slow its development in later life. Most UV light from the sun is filtered out by the atmosphere and consequently airline pilots often have high rates of cataracts because of the increased levels of UV radiation in the upper atmosphere. It is hypothesized that depletion of the ozone layer and a consequent increase in levels of UV light on the ground may increase future rates of cataracts. Note that the lens filters UV light, so
Earth Radiation Budget Satellite was one of three satellites in the ERBE and it carried two instruments as part of that effort. The ERBE scanner was a set of three detectors that studied longwave radiation, shortwave radiation and total energy radiating from the Earth along a line of the satellite's path. The ERBE non-scanner was a set of five detectors that measured the total energy from the Sun, and the shortwave and total energy from the entire Earth disk and the area beneath the satellite. The other two ERBE missions were included on the NOAA-9 satellite when it was launched in January 1985, and
