When welders don't properly protect their eyes from the arc, they commonly suffer welder's flash, or photokeratitis, a condition caused by exposure to intense ultraviolet radiation resulting in temporary blindness and extreme discomfort. More extreme eye injuries can result in permanent blindness.
Does welding mess up your eyes?
Exposure to infrared light can heat the lens of the eye and produce cataracts over the long term. Visible light from welding processes is very bright and can overwhelm the ability of the iris of the eye to close sufficiently and rapidly enough to limit the brightness of the light reaching the retina.
What is the life expectancy of a welder?
It can be varied from 1 to more than 40 years. Li et al. reported some cases with 36 years of working history as a welder (14). However in some other studies, there are cases with 40 years of experience in welding (15).
