Can Arc Welding Blind You
Yes, arc welding can blind you.
The ultraviolet (UV) and infrared (IR) radiation emitted by welding arcs can cause conjunctivitis, cataracts, temporary blindness, and eye fatigue.
Prolonged exposure to UV and IR rays can lead to conditions such as “surfer’s eye” (pterygium) and cataracts, which account for up to 20% of all cataract cases.
Welder’s flash burns, caused by UV radiation, are the most common type of eye injury in welding.
Wearing protective goggles or glasses is crucial in preventing these injuries and safeguarding the eyes from potential blindness.
Did You Know?
1. Welding fumes can be harmful to the eyes and may cause a condition known as arc eye, which is essentially like getting a sunburn on your eyeball.
2. Arc welding emits ultraviolet (UV) radiation, which can cause temporary or permanent damage to the eyes if proper eye protection is not worn.
3. Welding arc temperatures can reach up to 10,000 degrees Fahrenheit, which is hotter than the surface of the sun.
4. Welding helmets with auto-darkening filters protect the eyes by automatically adjusting the shade level based on the brightness of the arc, ensuring maximum safety and visibility for welders.
5. In certain situations, arc welding can produce intense visible light, known as the “arc flash,” which can be brighter than staring directly at the sun and can potentially cause temporary blindness if proper eye protection is not worn.
Welding Arcs Emitting UV and IR Radiation
Welding arcs emit both ultraviolet (UV) and infrared (IR) radiation, which can be highly dangerous if proper precautions are not taken.
UV radiation is particularly harmful and can cause “arc eye,” also known as conjunctivitis. This condition is characterized by redness, painful swelling, and watering of the eyes.
In addition to UV radiation, welding arcs also emit IR radiation and visible light. Exposure to these forms of radiation can cause temporary blindness and fatigue of the eyes.
Furthermore, prolonged exposure to UV and IR rays can result in more long-term effects, such as the development of “surfer’s eye” (pterygium) and cataracts. These conditions can significantly impair vision and may require surgery to correct.
To effectively protect against these risks, welders should take the following precautions:
- Wear appropriate eye protection, such as welding helmets or goggles equipped with shade lenses to block UV and IR radiation.
- Ensure that the eye protection is of adequate quality and approved for welding applications.
- Use protective clothing to cover exposed skin, as UV radiation can also cause skin damage and burns.
- Follow safe welding practices and avoid looking directly at the welding arc without proper eye protection.
Remember, taking these precautions is crucial for the safety and well-being of welders.
The Dangers of Long-Term UV Exposure
Long-term exposure to UV radiation emitted by welding arcs can have severe consequences for the eyes. Up to 20% of cataract cases are caused by UV radiation. Cataracts are a condition where the lens of the eye becomes clouded, leading to blurred vision and reduced visual acuity.
Moreover, exposure to UV radiation can also have adverse effects on the skin. Unprotected skin exposed to UV radiation from welding arcs can experience burns and may also be at risk for developing skin cancer. Therefore, it is crucial for welders to protect their skin as well as their eyes while working.
Protecting Against Infrared Radiation and Visible Light
It is crucial for welders to protect their eyes not only from UV radiation but also from infrared radiation and visible light, as these can cause temporary blindness and eye fatigue, especially in high intensities. Therefore, it is important for welders to shield their eyes from all three types of radiation.
One effective way to protect against infrared radiation and visible light is by wearing ANSI-approved welding helmets and goggles. These specialized eye protection gear are specifically designed to provide adequate shielding from these harmful radiations. In addition to the helmet, goggles or safety glasses with side-shields can also be worn to provide extra protection against debris.
To summarize the key points:
- UV, infrared radiation, and visible light all pose risks to welders’ eyes.
- High intensities of these radiations can cause temporary blindness and eye fatigue.
- Welders should use appropriate eye protection, such as ANSI-approved welding helmets and goggles.
- Goggles or safety glasses with side-shields can provide additional protection against debris.
The Risks of UV Radiation to Skin and Eyes
UV radiation emitted during arc welding presents risks not only to the eyes but also to the skin. Unprotected skin exposed to UV radiation can suffer burns, similar to a sunburn. These burns can be painful and may increase the risk of developing skin cancer.
In terms of eye health, welder’s flash burns are the most common type of eye injury in welding. Symptoms of arc weld flash burns include eye pain, blurred vision, sensitivity to light, and redness and swelling of the eyeballs. Treatment for flash burns may include acyclovir eye drops and wearing an eye patch. It is important to note that infection can be a possible complication.
Eye Protection: The Key to Preventing Eye Injuries in Welding
Considering the numerous risks posed by welding arcs to the eyes, wearing proper eye protection is crucial for welders. Protective goggles or glasses are the most effective way to prevent eye injuries and minimize the chances of blindness. It is alarming that eye injuries are the most common type of injury sustained by welders, despite the availability and effectiveness of eye protection.
However, it is important to acknowledge that some workers may not use goggles or safety glasses due to a lack of perceived risk or discomfort. To overcome this barrier, proper education and training on the dangers of UV and IR radiation and the importance of eye protection must be provided to all welders.
In conclusion, arc welding indeed poses risks to the eyes due to the emission of UV and IR radiation. These radiations can cause various eye conditions, such as arc eye, cataracts, and surfer’s eye. Protecting against UV radiation is not only crucial for eye health but also for the skin, as it can lead to burns and an increased risk of skin cancer. Therefore, wearing appropriate eye protection, such as ANSI-approved helmets or goggles, is essential to prevent eye injuries and maintain optimal visual health.

Frequently Asked Questions
Can arc welding damage your eyes?
Yes, arc welding can indeed damage your eyes. The intense optical radiation emitted during the welding process can cause various eye injuries. The primary condition associated with welding is photokeratitis, commonly referred to as ‘Welder’s eye.’ This condition occurs when the cornea becomes inflamed due to prolonged exposure to ultraviolet (UV) radiation emitted during arc welding. In addition to photokeratitis, other potential eye damages include keratoconjunctivitis, cataracts, and in rare cases, retinal injuries. Therefore, it is crucial for welders to wear appropriate protective eyewear to minimize the risk of eye damage and ensure their long-term eye health.
How quick can you get arc eye?
The onset of arc eye symptoms can vary, with some individuals experiencing them as early as 30 minutes after exposure, while others may not manifest any signs for up to 12 hours. This discrepancy in timing demonstrates that the speed at which arc eye develops can differ significantly from person to person. Thus, it is crucial to remain cautious and attentive after exposure to prevent potential damage to the eyes.
Is arc welding safer?
Arc welding can be safe if proper precautions are taken. However, it is important to note that if used incorrectly, it can pose significant risks to the operator. These risks include exposure to toxic fumes, burns, electric shock, and radiation, among others. Therefore, it is crucial for operators to be well-trained and adhere to safety guidelines to minimize the potential hazards and ensure a safe working environment.
Do welders get metal in their eyes?
Yes, welders are at risk of getting metal in their eyes if they do not wear suitable eye protection. Welding involves intense heat and the use of metal, which can result in small particles or larger pieces of dislodged metal flying into the welder’s eye. These fast-moving fragments can cause serious eye injuries such as lacerations, fractures, or puncture wounds. Therefore, it is crucial for welders to wear proper eye protection to prevent such accidents and protect their vision.
