"Arc eye" can be the result of gazing into an electric arc produced by an electric arc welder where the eyes are inadequately protected. What is the characteristic of the onset of symptoms such as pain, watering of the eyes, and gritty sensation like sand in the eyes?
⢠Arc eye (welderâs flash) is like a âsunburnâ on the clear surface of the eye (cornea) from intense ultraviolet (UV) radiation ⢠Consider how long it usually takes for a sunburn on skin to become painful after strong UV exposure ⢠Symptoms (pain, tearing, gritty/sandy feeling) are linked to how quickly damaged tissues react and become inflamed
⢠Think about whether tissue damage from UV light is usually felt right away or after a delay. Does pain from UV exposure (like sunburn) start immediately, or does it build up over time? ⢠Compare each optionâs time frame (immediate, hours, days, weeks) with what you know about other UV-related injuries, such as snow blindness or sunburn. ⢠Ask yourself: which time frame is commonly taught in basic first-aid or safety training for welderâs flash / snow blindness?
⢠Eliminate any options that describe a delay that seems too long for an acute injury caused by a single exposure. ⢠Question whether symptoms would be instant the moment exposure stops, or if there is usually a short latent period before irritation is noticed. ⢠Focus on the choices that describe a short delay after exposure, then decide which best matches how quickly inflamed tissues (like sunburned skin or cornea) typically start to hurt.
