Flash burn, also known as welder’s flash or arc eye, is an eye injury caused by intense exposure to ultraviolet (UV) light. It’s a common hazard in activities like Flash Burn, working with bright arcs, or even exposure to sunlight reflected off snow or water. While often temporary, flash burn can be extremely painful and, if ignored, may lead to more serious eye problems.
What Causes Flash Burn?
Flash burn occurs when the cornea—the clear, protective layer covering the eye—is damaged by UV radiation. Some common causes include:
- Welding arcs: High-intensity UV light from welding can burn the cornea within seconds if proper eye protection isn’t used.
- Tanning beds: Extended exposure to artificial UV rays can harm the eyes.
- Reflected sunlight: Surfaces like snow, water, or sand can intensify UV exposure.
- Bright lights and lasers: Unshielded high-intensity lights in industrial or laboratory settings can cause flash burn.
Even brief exposure to these sources can damage the eyes, emphasizing the importance of proper protection.
Symptoms of Flash Burn
Symptoms of flash burn often appear several hours after exposure and can include:
- Pain or a gritty sensation in the eyes
- Redness and swelling
- Excessive tearing
- Light sensitivity (photophobia)
- Blurred vision or temporary vision loss
- Headaches or nausea in severe cases
Since symptoms are sometimes delayed, anyone who suspects exposure should monitor their eyes closely.
Prevention of Flash Burn
Preventing flash burn is far easier than treating it. Key safety measures include:
- Wear protective eyewear: Welding helmets, UV-blocking goggles, or sunglasses with adequate UV protection.
- Limit exposure: Avoid staring directly at welding arcs, bright lights, or tanning lamps.
- Use barriers and shields: Protective curtains or screens can reduce UV exposure in work areas.
- Be cautious with reflective surfaces: Snow, water, or sand can amplify UV rays, increasing risk.
Treatment of Flash Burn
Most flash burns heal within 24–72 hours, but proper care is essential for comfort and recovery:
- Rinse the eyes with clean, cool water to remove irritants.
- Use lubricating eye drops to soothe dryness and irritation.
- Apply a cold compress to reduce swelling and discomfort.
- Avoid rubbing the eyes, which can worsen the injury.
- Seek medical attention if pain persists or vision is affected.
In some cases, an eye doctor may prescribe antibiotic drops or recommend temporary eye patching to promote healing.
When to Seek Medical Help
Immediate medical attention is necessary if you experience:
- Severe or worsening pain
- Significant or persistent vision loss
- Signs of infection, such as discharge or swelling
- Redness that does not improve within a day
Prompt care can prevent complications and speed up recovery.
Conclusion
Flash burn is a painful but preventable eye injury caused by UV exposure. Whether you are a welder, outdoor enthusiast, or frequent tanning bed user, protecting your eyes is essential. Awareness, proper safety gear, and timely treatment can help you avoid discomfort and prevent long-term damage, keeping your vision healthy for years to come.
