They call this condition arc eye, welder’s eye and arc flash.
CAN I WATCH THE ECLIPSE WITH SHADE 14 WELDING GLASS SKIN
Some UV radiation irritates and injures the skin and conjunctiva of the eye. This kind of light overheats the lens of your eye, increasing the risk of developing cataracts. Welders must protect themselves from blue light hazard, the scarring of the retina, which can cause blindness.
Blue light at 440 nanometers is particularly dangerous. The extremely bright light welders must stare at overwhelms your iris so it cannot close fast or far enough to protect your retina. The Bright Visible Light Also Endangers Welders When your cornea absorbs too much UV-B and UV-C, it’s at risk of snow blindness and permanent damage. * UV-C (200 to 280 nanometers) - absorbed by cornea of your eyeīecause your lens absorbs UV-A radiation, medical science associates it with long-term risk of cataracts. * UV-B (280 to 315 nanometers) - absorbed by the cornea of your eyes * UV-A (315 to 400 nanometers) - absorbed by the lens of your eye Scientists divide ultraviolet radiation into three types: * Infrared radiation (700 to 14,000 nanometers) * Ultraviolet radiation (200 to 400 nanometers) Welding arcs give off radiation ranging from 200 nanometers to 14,000 nanometers. However, even though unseen, they burn retinas. The flame of the welding torch puts out a bright light, including ultraviolet light and radiation waves the human eye cannot see. Chemical gases and fumes might irritate their eyes. Flying dust particles and debris might hit them there. One-quarter of all injuries from welding damage the eye. Welding is a risky occupation, and they are most at risk for eye injuries, according to the Liberty Mutual Research Institute for Safety. Welders Need Powerfully Protective Glasses However, except for that brief period when it’s 100% blocked by the Moon, the Sun’s light can still blind you.
You’re in the middle of a cone of night surrounded by normal daylight. You can see the stars in the sky even though far off, on the horizon around you, the Sun is still shining. During the totality, the Moon turns day into night. In 2017, while over North America, the totality phase of the eclipse will last from 1 minute 43 seconds to 2 minutes 41 seconds while it’s over Shawnee National Forest just south of Carbondale, Illinois. The time the sun spends totally blocked varies. Outside it, people will still know the eclipse is happening, but they won’t experience the point when the Moon totally covers the Sun. The 2017 solar eclipse will have a band of totality about 67 miles in diameter. Because the Moon is smaller than the Sun, although much closer to Earth, the shadow it casts is a narrow band. However, when the Moon’s apparent diameter is large enough to fully block out the Sun’s light, that’s a total solar eclipse. Usually it’s only a partial shadow or eclipse. With the Sun’s source of light behind the Moon, it casts its shadow on the Earth. Because the Moon’s orbit is elliptical, every once in a great while the Moon comes between the Earth and the Sun. You’ll enjoy it most if you protect your eyesight with Shade 14 solar eclipse glasses.Īs the Earth rotates once every 24 hours while revolving around the Sun once a year, the Moon revolves around the Earth at a 5 degree angle every four weeks, creating the lunar cycle. It’s also the first total solar eclipse to sweep the entire width of the United States from West Coast (Oregon) to East Coast (South Carolina) since 1918. Next year, August 21, 2017, millions of people will experience the most spectacular astronomical event, the first total solar eclipse to hit North American since 1979.
