Why Does Arc Welding Hurt Your Eyes?

Arc welding can hurt your eyes due to the intense light and radiation produced during the process. The bright arc generates ultraviolet (UV) and infrared (IR) radiation, which can damage the eyes if proper protection is not used.

The American National Standards Institute (ANSI) defines ultraviolet (UV) radiation as a portion of the electromagnetic spectrum that can cause sunburns and other forms of skin and eye damage. It is crucial to understand that the light produced during arc welding is vastly more intense than natural sunlight, making eye protection essential.

The underlying causes of eye pain from arc welding are primarily related to exposure to harmful radiation. When you gaze directly at the welding arc, the bright light can overwhelm the retina, leading to a painful condition known as “welder’s flash” or photokeratitis. In simple terms, this is like getting a sunburn on your eyes. Furthermore, the heat generated by the arc can also contribute to discomfort.

Ultraviolet (UV) radiation is one type of harmful radiation emitted during welding. Blocking this radiation is critical because prolonged exposure can lead to significant damage. For instance, UV radiation can cause cataracts, a condition where the lens of the eye becomes cloudy. Infrared (IR) radiation, on the other hand, can cause thermal burns to the eye’s surface.

Detailed explanations suggest that when welding, the eyes are exposed to the intense light and radiation that can sear the cornea, leading to immediate discomfort. The pain may not be felt immediately but can occur hours after exposure. The process of photokeratitis involves the death of superficial cells on the cornea, leading to symptoms such as tearing, redness, and a gritty feeling in the eyes.

Specific conditions that contribute to eye pain during arc welding include not wearing appropriate eye protection such as a welding helmet or goggles. For example, a welder who fails to shield their eyes adequately while working in an unprotected environment is at a higher risk of developing eye pain. Moreover, a dark environment can exacerbate sensitivity to the bright arc, increasing the likelihood of discomfort.

In summary, arc welding hurts your eyes primarily due to exposure to intense light and harmful UV and IR radiation. Using appropriate eye protection is essential in preventing this painful experience.
