Flash burn, also known as arc eye or welder’s flash, is a painful eye condition caused by overexposure to ultraviolet (UV) light. It commonly affects Flash Burn, construction workers, and anyone exposed to intense light sources, including sunlight reflecting off snow or water. While usually temporary, flash burn can be extremely uncomfortable and, in repeated cases, may lead to long-term eye damage.
What Causes Flash Burn
Flash burn occurs when the cornea—the transparent front layer of the eye—is damaged by ultraviolet radiation. Common sources include:
- Welding arcs: Intense UV light from electric arcs can burn the cornea in seconds.
- Tanning beds: Artificial UV radiation from tanning lamps can damage the eyes if protective eyewear is not used.
- Sunlight reflections: Bright sunlight reflecting off water, snow, or sand can lead to temporary flash burns.
Even brief exposure can be enough to trigger a flash burn, which is why protective eyewear is essential in high-risk situations.
Symptoms of Flash Burn
Symptoms typically appear a few hours after exposure and can last 24–48 hours. They include:
- A gritty or burning sensation in the eyes
- Redness and swelling
- Excessive tearing or watery eyes
- Sensitivity to light (photophobia)
- Blurred vision
- Headache or nausea in severe cases
Recognizing these symptoms early is crucial for prompt treatment and relief.
Preventing Flash Burn
Preventing flash burn is far easier than treating it. Key measures include:
- Wear UV-protective eyewear: Welding helmets, safety goggles, or sunglasses that block UV rays.
- Limit exposure: Avoid staring directly at intense light sources.
- Use shielding: Physical barriers, such as curtains or shields, can reduce reflected UV light.
- Be cautious outdoors: Snow, water, and sand can intensify UV exposure.
Regular use of protective measures can prevent both acute injuries and long-term eye damage.
Treatment for Flash Burn
Most flash burns heal on their own within 24–72 hours, but proper care can ease discomfort:
- Rinse the eyes with clean, cool water to remove irritants
- Lubricating eye drops can reduce dryness and irritation
- Cold compresses may relieve pain and swelling
- Avoid rubbing your eyes, which can worsen the injury
In severe cases, an eye doctor may prescribe antibiotic eye drops or recommend temporary eye patching.
When to Seek Medical Attention
Seek professional care if you experience:
- Severe or worsening pain
- Persistent blurred vision
- Redness or swelling that does not improve
- Signs of infection, such as discharge
Prompt medical attention can prevent complications and support faster recovery.
Conclusion
Flash burn is a painful but preventable eye injury caused by UV exposure. Whether at work or outdoors, protecting your eyes with proper eyewear and caution is essential. By understanding the causes, recognizing early symptoms, and taking preventive measures, you can enjoy your activities safely without risking long-term damage to your vision.
