Common signs and symptoms of Welding Flash Burns (Arc Eye) include:
When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Welding Flash Burns (Arc Eye).
Arc eye results from ultraviolet radiation burns to the cornea and conjunctiva, the clear tissues covering the front of the eye.
Arc eye results from ultraviolet radiation burns to the cornea and conjunctiva, the clear tissues covering the front of the eye. When intense UV light from welding arcs hits these delicate surfaces, it damages the outermost cells much like a sunburn damages skin. The UV radiation breaks down proteins in the corneal epithelium, causing the protective surface layer to become inflamed and painful.
The welding arc produces both UV-A and UV-B radiation, with UV-B being particularly damaging to eye tissues.
The welding arc produces both UV-A and UV-B radiation, with UV-B being particularly damaging to eye tissues. This invisible light penetrates the cornea and triggers an inflammatory response that doesn't become apparent until several hours after exposure. The delayed onset occurs because it takes time for the damaged cells to release inflammatory chemicals that cause pain and swelling.
Direct exposure to welding light causes the most severe burns, but even reflected UV radiation from shiny surfaces can damage eyes.
Direct exposure to welding light causes the most severe burns, but even reflected UV radiation from shiny surfaces can damage eyes. The intensity of modern welding equipment means that even brief, seemingly harmless glances at an unshielded arc can cause significant injury. Other sources of similar UV burns include carbon arc lamps, germicidal lamps, and intense sunlight reflected off snow or water.
Risk Factors
- Working as a welder or in metalworking industries
- Being near welding operations without proper eye protection
- Apprentices or new workers unfamiliar with safety protocols
- Using damaged or inadequate welding helmets
- Working in areas with reflective metal surfaces
- Exposure to other intense UV sources like carbon arc lamps
- Bystanders in welding shops or construction sites
- Failure to use safety glasses under welding helmets
- Working outdoors with intense sun reflection off metal or snow
Diagnosis
How healthcare professionals diagnose Welding Flash Burns (Arc Eye):
- 1
Doctors typically diagnose arc eye based on the patient's history of UV exposure and characteristic symptoms.
Doctors typically diagnose arc eye based on the patient's history of UV exposure and characteristic symptoms. The combination of severe eye pain developing hours after welding exposure, along with light sensitivity and tearing, strongly suggests photokeratoconjunctivitis. Medical professionals will ask detailed questions about when the exposure occurred, what type of welding was involved, and whether proper eye protection was used.

A thorough eye examination using a slit lamp microscope reveals the extent of corneal damage.
A thorough eye examination using a slit lamp microscope reveals the extent of corneal damage. The doctor may instill fluorescent dye drops that make damaged areas of the cornea glow bright green under special blue light. This technique, called fluorescein staining, shows exactly where the UV radiation has injured the corneal surface. The pattern of damage often covers the central cornea in a characteristic distribution.

Healthcare providers will also check for foreign particles that might have entered the eye during welding, examine the eyelids for burns, and test visual acuity.
Healthcare providers will also check for foreign particles that might have entered the eye during welding, examine the eyelids for burns, and test visual acuity. They'll rule out more serious injuries like corneal ulcers, chemical burns, or penetrating trauma that might require different treatment approaches. Most cases of arc eye show typical findings that confirm the diagnosis without need for additional testing.
Complications
- Most cases of arc eye heal completely without lasting effects, but complications can develop in severe cases or when treatment is delayed.
- Secondary bacterial infections represent the most common complication, occurring when damaged corneal tissue becomes infected.
- These infections can cause corneal scarring that affects vision if not treated promptly with appropriate antibiotics.
- Recurrent corneal erosion sometimes develops weeks or months after the initial injury.
- This condition causes the healed corneal surface to break down repeatedly, leading to episodes of sudden, severe eye pain.
- While uncomfortable, recurrent erosions usually respond well to lubricating treatments and protective contact lenses.
- Rarely, severe or repeated UV burns can cause permanent corneal scarring that affects visual clarity and may require surgical intervention to restore optimal vision.
Prevention
- Installing welding screens to protect bystanders from reflected UV light
- Ensuring all workers in welding areas wear safety glasses even when not actively welding
- Training employees about UV radiation hazards and proper equipment use
- Regular inspection and maintenance of protective equipment
- Posting warning signs in areas where welding occurs
Treatment for arc eye focuses on pain relief and protecting the healing corneal surface.
Treatment for arc eye focuses on pain relief and protecting the healing corneal surface. Doctors typically prescribe topical anesthetic drops for immediate pain relief, though these should only be used under medical supervision as overuse can delay healing. Oral pain medications like ibuprofen or acetaminophen help manage discomfort and reduce inflammation throughout the recovery period.
Antibiotic eye drops or ointments prevent secondary bacterial infections while the damaged corneal surface heals.
Antibiotic eye drops or ointments prevent secondary bacterial infections while the damaged corneal surface heals. These medications create a protective barrier and reduce the risk of complications. Cool, damp compresses applied to closed eyelids provide additional comfort and help reduce swelling and inflammation.
Patients should avoid bright lights and wear sunglasses both indoors and outdoors during recovery.
Patients should avoid bright lights and wear sunglasses both indoors and outdoors during recovery. Staying in dimly lit environments reduces light sensitivity and allows the eyes to rest. Lubricating eye drops without preservatives help keep the healing corneal surface moist and comfortable.
Most people recover completely within 24 to 48 hours with proper treatment.
Most people recover completely within 24 to 48 hours with proper treatment. Severe cases might require stronger prescription pain medications or specialized contact lenses that protect the cornea while it heals. Follow-up appointments ensure proper healing and check for any complications that might require additional intervention.
Living With Welding Flash Burns (Arc Eye)
Recovery from arc eye requires patience and careful attention to eye comfort during the healing process. Most people can return to normal activities within 48 hours, though some may need a few extra days if symptoms persist. During recovery, staying in dimly lit environments and wearing sunglasses helps manage light sensitivity and promotes healing.
