What Is Welding Flash
Welding flash, also known as photokeratitis, is a painful eye condition caused by exposure to ultraviolet (UV) rays, particularly from welding torches.
It occurs when unprotected eyes are exposed to UV rays that damage the outer layer of the cornea.
Welders are at risk for photokeratitis due to exposure to bright flashes or “arcs” of UV radiation while welding.
Symptoms include intense pain in the affected eye(s) and may appear as early as 30 minutes after UV exposure.
Treatment options include applying antibiotic ointment, using artificial tears, taking oral pain medication, and wearing glasses instead of contact lenses until the cornea is healed.
It usually takes one to two days for welder’s flash to heal after UV exposure.
It is recommended to wear protective eyewear or sunglasses and seek medical attention promptly if experiencing symptoms.

Introduction To Welding Flash
Welder’s flash, also known as photokeratitis, is a painful eye condition that occurs as a result of exposure to ultraviolet (UV) rays, particularly those emitted by welding torches. The sensation experienced by individuals with welder’s flash is often described as a sunburn on the eyes. In addition to arc eye, it is also referred to as flash burn, ultraviolet keratitis, and snow blindness.
Photokeratitis is a condition that arises when the eyes are subjected to UV rays without adequate protection. The ultraviolet radiation damages the epithelium, which is the outer layer of the cornea. This damage causes the cells of the cornea to slough off, leaving the corneal nerves exposed and vulnerable to further harm.
Welders, who are frequently exposed to bright flashes or “arcs” of UV radiation during the welding process, are at a heightened risk of developing photokeratitis.
However, it is important to note that photokeratitis can also occur in outdoor settings with bright reflective surfaces, such as snow, water, and sand. Broken high-intensity light bulbs in indoor settings and specific types of lamps or lights can also cause this condition. It is crucial for individuals engaging in these activities or working with such equipment to be aware of the risks associated with welder’s flash.
Causes And Risk Factors Of Welder’s Flash
The primary cause of welder’s flash is exposure to UV rays, specifically the ultraviolet radiation emitted by welding torches. The intense flashes or “arcs” produced during welding contain high levels of UV light that can be harmful to the eyes. Without proper protection, these UV rays can lead to photokeratitis.
In addition to welding activities, other situations can give rise to welder’s flash. Outdoor environments with bright reflective surfaces, such as snow, water, and sand, can also expose individuals to significant amounts of UV radiation. Furthermore, broken high-intensity light bulbs in indoor settings and certain types of lamps or lights can emit UV rays capable of causing photokeratitis.
- Welders
- Construction workers
- Individuals engaged in activities involving bright flashes or UV radiation
These individuals are particularly susceptible to developing welder’s flash. It is essential for them to take necessary precautions to prevent this painful eye condition.
Symptoms And Diagnosis Of Welder’s Flash
The symptoms of welder’s flash can manifest as early as 30 minutes after exposure to UV rays, but in some cases, they may take up to 12 hours to appear. The most common symptom is intense pain in the affected eye. If both eyes were exposed to UV rays, the pain may be present in both eyes. Other symptoms may include redness, tearing, increased sensitivity to light, a gritty sensation in the eyes, and blurry vision.
To diagnose welder’s flash, an eye doctor will perform a thorough examination. They will inquire about the individual’s recent activities and exposure to UV radiation and may also use a special dye to evaluate the condition of the cornea. It is crucial to seek proper medical attention for an accurate diagnosis, as some symptoms of welder’s flash may resemble those of other eye conditions.
Treatment And Healing Process For Welder’s Flash
Effective treatment for welder’s flash includes a combination of various measures. Initially, the doctor may prescribe the application of a topical antibiotic ointment to prevent infection. Artificial tears may also be recommended to alleviate dryness and discomfort. Additionally, oral pain medication may be prescribed to manage the intense pain associated with the condition.
During the healing process, it is important to refrain from wearing contact lenses and instead opt for wearing glasses until the cornea has completely healed. The duration required for the healing process varies, but it typically takes one to two days for welder’s flash to resolve after exposure to UV radiation.
It is crucial to note that unverified home remedies should be avoided. Seeking professional medical advice is always recommended to ensure proper treatment and avoid complications.
Prevention And First Aid For Welder’s Flash
Prevention is key to avoiding the discomfort and potential damage caused by welder’s flash. One of the most effective preventive measures is wearing specially manufactured goggles or a helmet designed to shield the eyes from UV radiation. These protective gear items are essential for welders, construction workers, and individuals engaged in activities with high UV exposure.
In outdoor settings, wearing sunglasses that offer comprehensive UV protection is vital. This is especially crucial in environments with bright reflective surfaces, such as snow, water, and sand, as they intensify UV radiation. Indoors, it is important to ensure the quality and functionality of lights and lamps, promptly replacing any broken high-intensity bulbs.
In the event that someone experiences welder’s flash, immediate first aid is crucial. The affected individual should be removed from any light source and their eyes should be flushed with an appropriate eye wash or saline solution. Seeking prompt medical attention is essential to determine the extent of corneal damage and potential complications.
To mitigate the risks associated with welder’s flash, individuals should prioritize proper prevention methods and promptly seek medical assistance in case of exposure to UV radiation. By following these precautions, the occurrence of this painful eye condition can be significantly reduced.
Preventive measures:
- Wear specially manufactured goggles or a helmet designed to shield the eyes from UV radiation.

Frequently Asked Questions
What causes welding flashes?
Welding flashes, also known as arc-eye or welder’s flash, are triggered by the intense ultraviolet radiation emitted by the welding arc. When a welder is exposed to this harmful UV light without proper eye protection, it can cause inflammation of the cornea, leading to arc-eye. The symptoms of arc-eye often take several hours to manifest, which can often mislead individuals into not realizing the extent of their exposure until after the damage has occurred.
Is welding flash UV light?
Welding flash does indeed emit UV light. Both electric arc and laser welding processes generate UV radiation which poses a risk to welders. During welding, not only are you directly exposed to the UV radiation emitted by the welding arc, but you are also at risk from the UV radiation that is reflected off nearby hard and smooth surfaces. It is crucial for welders to take necessary precautions, such as wearing appropriate protective gear and ensuring proper ventilation, to minimize the harmful effects of UV radiation.
What is flash arc welding?
Flash arc welding is a variant of resistance welding that harnesses the power of an electrical arc to join metal pieces together. Unlike traditional flash welding, which does not involve any filler metals, flash arc welding utilizes an electrical arc to heat up and melt the edges of the metal pieces to be joined. The pieces of metal are initially set at a specific distance based on factors such as material thickness, composition, and desired weld properties. Once the arc is initiated, the extreme heat generated causes the edges of the metal to melt and fuse, creating a strong and durable weld joint.
What is flash and burn?
Flash and burn refers to a distressing condition caused by exposure to intense ultraviolet (UV) light, resulting in an acute inflammation of the cornea. When subjected to bright UV light, such as that emitted by welding torches or other sources, the cornea becomes inflamed and painful. This type of injury, commonly known as a flash burn, causes significant discomfort and requires immediate attention to prevent further damage to the eyes. The intensity of the UV light is the main factor contributing to flash burns, making it crucial to protect the eyes adequately when working with welding torches or in similar circumstances.
