Arc eye (welder's flash, photokeratitis) symptoms, caused by intense UV light, include severe eye pain, redness, excessive tearing, blurred vision, swelling, and extreme light sensitivity, typically appearing 6-12 hours after exposure, feeling like sand in your eyes, and usually resolving within 24-48 hours with proper care like cool compresses, numbing drops, or rest.

About flash burns
That's why it's sometimes called 'welder's flash' or 'arc eye'. Flash burns are like sunburn in the eye and can affect both your eyes. Your cornea can repair itself in one to two days, and usually heals without leaving a scar. However, if the flash burn is not treated, an infection may start.
What are the symptoms of "arc eye"?
It can be caused by unprotected exposure to the bright flash from a welding arc (the classic example). Other causes of arc eye include exposure to strong halogen lamps, photographic flood lamps, lasers, germicidal and laboratory UV lights.
Common arc eye symptoms include pain, teary eye(s), swelling, a gritty feeling in the eye, blurriness, sensitivity to bright light, eyelid twitching and headache. You are likely to experience pain, watering and sensitivity to light. Eyelid muscle spasms are also common, making it difficult to open the eye.
Recognising the symptoms of arc eye and knowing how to treat it can help ensure a quick recovery. More importantly, taking proper precautions – such as wearing protective eyewear and limiting exposure – can prevent the condition entirely.
The best way to prevent welding arc eye injuries is to wear an appropriate welding helmet for the job at hand. High quality welding helmets protect you from harmful UV and IR radiation.
You may have arc eye if your eyes start to feel uncomfortable a few hours after exposure to bright UV light, such as welding. Common signs include burning, redness, and a strong urge to rub your eyes. Many people also notice blurred vision, swelling around the eyes, and difficulty keeping the eyes open.
Radiation in the ultraviolet range emitted by arc welders is absorbed by the unprotected cornea and lens, giving rise to a keratoconjunctivitis, or 'arc-eye,' which, though intensely painful, is not considered a threat to sight.
Do potatoes help welders flash? Using raw potatoes for welder's flash is a folk remedy without scientific backing. While the coolness of a potato slice may provide temporary relief, it doesn't treat the underlying UV damage to the cornea.
Conclusions. Chronic exposure to welding light may cause color vision deficiency. The damage depends on the exposure duration and the length of their employment as welders.
Corneal flash burns are a burn injury on the front of your eye. They can be from UV sources like welding torches, reflected sunlight or from heat-related sources like open flames or explosions. They're very treatable and usually heal within a few days.
This causes superficial burning to the front of the eye(s) and occasionally the eyelids and develops 6-10 hours after the incident. As this area is very sensitive it is a painful condition but will heal up within 24-48 hours without any long-term complications.
This is reversible corneal damage caused by UV radiation. The typical onset is not immediate after injury but can take up to 12 hours to begin. On fluorescein staining there is superficial punctate staining.
Early signs of an eye stroke (retinal artery occlusion or ischemic optic neuropathy) typically involve sudden, painless vision loss or changes, most often in only one eye, including blurred vision, blind spots, floaters, or a dark shadow covering part of your sight. It often happens upon waking and is a medical emergency requiring immediate attention to potentially save sight and identify a risk for a full stroke.
First Aid Only M702 Welder's Arc Eye Drops offer immediate relief for welder's eye discomfort. The M702 is designed to soothe irritation caused by harmful light and foreign materials. Each bottle contains half an ounce of eye drops, suitable for emergency eye care.
Arc-eye occurs when the surface of the eye is exposed to excessive ultraviolet (UV) radiation—usually when an arc is accidentally struck while the welding helmet is in the up position or the eyes are otherwise unprotected. Long-term over-exposure to arc radiation is linked to retinal burns, cataracts and skin cancer.
Exposure to harmful fumes and gases
Even in open spaces, over time, exposure to carcinogens like hexavalent chromium, cadmium, beryllium, nickel, arsenic, and substances causing neurological damage, such as manganese, can shorten a welder's life.
Wring out excess water and find a comfortable spot to lie back. Place the cold gauze pads over the eye and keep them in place until they are warm. Repeat the process if you are still experiencing pain or swelling. You can also boil a tea bag for two minutes, then place in the refrigerator to cool.
Radiation intensity is strongly dependent on the distance from a welder's arc. Therefore, if you are a short distance from an arc, even a very short exposure to the arc flash can result in injury. As a result, personnel must be subject to adequate protection if they're closer than 10 metres from an arc flash.
Yes, you absolutely can make $100,000 a year welding, but it usually requires specialization, advanced skills, experience, and often travel or hazardous conditions, with roles like pipeline or underwater welding offering the highest potential, though even general welders can reach this with hustle, owning equipment, and working in high-demand areas. Entry-level pay is lower, but significant growth is possible, with top earners exceeding six figures through dedication and strategic career moves.
This condition is also known as Arc Eye and Snow Blindness. It is caused when the eyes are exposed to too much ultraviolet (UV) light. After a delay of 6 to 12 hours following exposure to arc welding, sun lamps or other sources of UV light, the eyes become red, painful, watery and unduly sensitive to light.
