How Does a Retinal Burn Develop from Exposure to a Welding Arc?
A retinal burn develops from exposure to a welding arc due to intense light and heat. The welding arc emits ultraviolet (UV) light and visible light in high intensity. This light can damage the retina, the light-sensitive layer at the back of the eye. When unprotected eyes face the welding arc, the intense light overwhelms the retinal cells. These cells absorb the harmful UV rays and visible radiation, leading to thermal and photochemical damage.
First, identify the exposure to the welding arc. The exposure lasts from a few seconds to several minutes. Next, the intensity of the arc produces a sudden increase in light that the eyes cannot adjust to quickly. The symptoms of retinal burns can include pain, blurred vision, and temporary or permanent vision loss.
Sunlight can also cause similar damage, as it contains UV rays. However, the welding arc emits significantly higher levels of UV radiation. This makes it particularly hazardous for eyes when proper protection is absent. In summary, the combination of intense light and UV radiation from a welding arc causes retinal burns by overwhelming the retina, leading to potential long-term vision issues.
