Why Does Welding Hurt Your Eyes
Welding hurts your eyes because the welding arcs emit radiation, including UV radiation.
UV radiation in certain ranges can cause “arc eye” or conjunctivitis, which leads to pain, tearing, redness, sensitivity to light, and the inability to look at light sources.
Exposure to just a few seconds of intense UV light can cause arc eye.
Long-term exposure to UV light can also result in cataracts.
Furthermore, while infrared radiation and visible light have little effect on the skin, UV radiation can burn unprotected skin and lead to skin cancer with prolonged exposure.
Did You Know?
1. In welding, the intense ultraviolet (UV) and infrared (IR) radiation emitted can cause a condition known as “arc eye,” which is essentially a sunburn on the surface of the eye.
2. Welding arcs can reach temperatures of up to 5,500 degrees Celsius (9,932 degrees Fahrenheit), which is hotter than the surface of the sun!
3. The use of protective eye gear, such as welding goggles or a welding helmet with a dark visor, helps to block harmful UV and IR radiation, reducing the risk of eye damage.
4. Apart from the intense light, welding also releases toxic fumes and gases, which can be harmful if inhaled. Thus, using proper ventilation or wearing a respirator is crucial for welders’ safety.
5. Multiple studies have shown that prolonged exposure to welding fumes may increase the risk of developing lung cancer, making respiratory protection an essential aspect of welding safety measures.
Welding Arcs And Radiation: A Hazardous Combination For Your Eyes
Welding is an essential process in various industries, but it poses potential risks to the welder’s eyes. The main risk factor in this case is the radiation emitted by welding arcs. These arcs emit radiation across different wavelengths, including ultraviolet (UV) radiation, visible light, and infrared (IR) radiation. While visible light and IR radiation have minimal impact on the eyes, UV radiation can be particularly harmful.
To protect the welder’s eyes from the hazards of UV radiation, proper safety measures should be followed. Some recommendations include:
- Wearing appropriate eye protection such as welding helmets with specialized lenses that filter out UV radiation.
- Ensuring the lenses are in good condition and properly darkened to reduce the amount of UV radiation reaching the eyes.
- Using welding curtains or shields to block any scattered radiation that may pose a risk.
- Maintaining a safe distance from the welding arc to reduce direct exposure to UV radiation.
By taking these precautions, welders can minimize the potential damage caused by UV radiation and safeguard their eyes.
Understanding UV Radiation And Its Impact On Welders
UV radiation, divided into UV-A, UV-B, and UV-C ranges, has the potential to cause significant harm to the eyes when exposed to welding arcs. UV-C, the most harmful type, is fortunately absorbed by the Earth’s atmosphere and does not reach the surface. UV-B radiation is partially absorbed by the cornea and lens of the eye, while UV-A can penetrate even deeper, posing a risk to the retina.
When eyes are unprotected and exposed to intense UV radiation from welding arcs, serious eye conditions can develop, such as arc eye or conjunctivitis. This condition includes symptoms like pain, tearing, redness, sensitivity to light, and an inability to look at light sources. Even a few seconds of intense UV light can cause arc eye, underscoring the necessity for welders to take preventive measures.
The Dangers Of Arc Eye: Symptoms And Effects
Arc eye, also known as welder’s flash, is a painful condition that occurs when the surface of the eye, particularly the conjunctiva, is damaged by exposure to intense UV radiation. The symptoms of arc eye usually appear within a few hours of exposure and can last for several days. Besides the immediate pain and discomfort, it can also lead to temporary vision loss. If left untreated, arc eye can result in long-term complications or even permanent vision damage.
In addition to arc eye, long-term exposure to UV radiation during welding can lead to the development of cataracts. Cataracts cause clouding of the eye’s lens, resulting in blurry vision and visual impairment. The risk of cataracts significantly increases with prolonged UV exposure, making it crucial for welders to prioritize eye protection and minimize their exposure to harmful radiation.
Short-Term And Long-Term Consequences Of UV Exposure During Welding
The immediate consequences of UV exposure during welding are evident and painful. The short-term effects include the aforementioned arc eye symptoms, such as pain, tearing, redness, sensitivity to light, and temporary vision loss. These symptoms may take a few hours to develop and can cause considerable discomfort for the welder.
However, the long-term consequences of UV exposure are equally concerning. Prolonged exposure to UV radiation during welding can lead to the development of cataracts, as mentioned earlier. Not only can cataracts negatively impact a welder’s ability to perform their job effectively, but it can also result in visual impairment in their day-to-day life. Thus, protecting the eyes from UV radiation is crucial for maintaining long-term eye health.
Skin Protection: The Hidden Risk Of UV Radiation During Welding
While the focus is often on the effects of UV radiation on the eyes, it is important not to overlook the impact it can have on the skin. UV radiation emitted during welding can burn unprotected skin, leading to painful sunburn-like symptoms. Moreover, long-term exposure to UV radiation can increase the risk of skin cancer.
Welders frequently face a hidden risk of UV radiation on their skin, as the process typically requires the arms, neck, and face to be exposed. To mitigate this risk, welders should wear protective clothing that covers as much skin as possible. This includes long-sleeved shirts, pants, and hats with wide brims or neck flaps.
In conclusion, welding arcs emit various forms of radiation, including UV radiation that can be harmful to the eyes. Exposure to intense UV light can cause arc eye, which is characterized by symptoms such as pain, tearing, redness, and sensitivity to light. Long-term exposure to UV radiation can lead to cataracts and increase the risk of skin cancer. To prevent these risks, welders must prioritize eye protection measures and ensure adequate coverage of their skin to minimize UV exposure. Taking these precautions will help safeguard the eyes and overall health of welders in the long run.

Frequently Asked Questions
Do welders have bad eyesight?
Welders can be at risk of developing ocular damage due to the exposure to optical radiation during their work. One of the common eye conditions among welders is photokeratitis, also referred to as ‘Welder’s eye.’ This condition is a form of corneal inflammation caused by intense ultraviolet (UV) radiation from the welding arc. While welders are more susceptible to these eye issues, not all welders will experience significant long-term damage to their eyesight as a result. It is vital for welders to take appropriate safety precautions, such as wearing protective goggles and using proper shielding, to minimize the risk of developing eye-related problems.
Can your eyes heal from welding?
Flash burns, also known as “welder’s flash” or “arc eye,” can cause damage to the eyes similar to sunburn. These burns affect the cornea and can affect both eyes. Fortunately, the cornea has the ability to heal itself within a span of one to two days, often leaving no scarring. It is crucial to properly treat flash burns, as neglecting them may lead to the development of infections.
How do you get rid of welders eyes?
To alleviate welder’s eye, a variety of treatments are available. One approach involves employing specialized eye drops or ointments that have both topical and antibiotic properties, effectively safeguarding the cornea against possible infections. The use of steroid eye drops by certain eye doctors can effectively minimize inflammation and the subsequent risk of scarring, ensuring a better recovery for the affected individual.
Why do eyes hurt after welding?
Eyes can hurt after welding due to the exposure to harmful UV light emitted during the welding process. This includes all types of UV light, with welders being particularly vulnerable to this phenomenon, often referred to as ‘Welder’s flash’ or ‘Arc eye’. The intense UV light causes a painful inflammation of the cornea, comparable to the sensation of a sunburn in the eye. As a result, both eyes can be affected, leading to discomfort and soreness.
