How Welding Affects Your Eyes

UV Radiation Exposure

UV radiation is a major concern in welding. Exposure to UV rays can cause damage to the eyes, leading to conditions like welder’s flash, also known as arc flash or flash burn. Welder’s flash occurs when the eyes are exposed to intense UV radiation without proper protection. Symptoms include eye pain, redness, sensitivity to light, and excessive tearing.

Infrared Radiation Exposure

Infrared radiation is another hazard in welding that can impact eye health. Prolonged exposure to IR radiation can result in discomfort, dryness, and irritation of the eyes. The heat generated by welding can cause a sensation similar to sunburn on the surface of the eye, known as arc eye or photokeratitis.

Intense Visible Light Exposure

The bright light emitted during welding can be harmful to the eyes. Staring directly at the welding arc without eye protection can cause temporary vision impairment and even permanent damage. Symptoms include eye fatigue, difficulty focusing, and decreased color perception.

Impact of Welding Fumes

In addition to the radiation hazards, welding fumes can also affect eye health. These fumes contain toxic substances, such as metal oxides and gases, which can cause irritation, redness, and itching of the eyes. Prolonged exposure to welding fumes may contribute to the development of more severe eye conditions, such as conjunctivitis and cataracts.

Symptoms and Effects of Eye Injuries in Welding

Now that we understand the potential hazards, let’s explore the specific eye injuries that can occur due to welding.

Welder’s Flash

Welder’s flash, as mentioned earlier, is a painful condition caused by exposure to intense UV radiation. The symptoms typically appear several hours after exposure and include a gritty sensation in the eyes, excessive tearing, sensitivity to light, and blurred vision. Fortunately, the welder’s flash is usually temporary and resolves within a day or two.

Arc Eye

Arc eye, also known as welder’s keratitis or photokeratitis, is a condition that occurs when the eyes are exposed to high levels of UV radiation or intense visible light. Symptoms include severe eye pain, redness, tearing, blurred vision, and a feeling of foreign objects in the eyes. Arc eye may take a few days to heal, and medical attention should be sought if symptoms persist.


Welding fumes can cause conjunctivitis, an inflammation of the conjunctiva, which is the thin, transparent layer covering the white part of the eyes and the inner surface of the eyelids. Symptoms include redness, itching, watering of the eyes, and a gritty or burning sensation. Conjunctivitis is typically treatable and resolves within a few days.


Long-term exposure to the hazards of welding, particularly UV radiation, may increase the risk of developing cataracts. Cataracts are characterized by clouding of the eye’s natural lens, leading to blurred vision, sensitivity to light, and reduced color perception. Surgery is often required to remove cataracts and restore clear vision.

Retinal Burns

Direct exposure to the intense light produced during welding can cause retinal burns, which damage the light-sensitive tissue at the back of the eye. Retinal burns can result in permanent vision loss or impairment. It is crucial to prioritize eye protection to prevent such severe injuries.

Home Remedies and Self-Care

In addition to seeking medical attention, there are some home remedies and self-care practices you can adopt to speed up the healing process and alleviate discomfort.

Cold Compresses

Applying a cold compress to your closed eyes can help reduce inflammation and relieve pain. You can use a clean cloth soaked in cold water or a bag of frozen vegetables wrapped in a thin towel.

Resting the Eyes

Giving your eyes ample rest is crucial for their recovery. Avoiding activities that strain the eyes, such as reading, watching screens, or exposure to bright lights, can aid in the healing process.

Wearing Protective Eyewear

Prevention is key when it comes to eye safety during welding. Ensure you wear appropriate protective eyewear, such as welding goggles or helmets with tinted lenses specifically designed to block UV radiation and protect against debris and sparks.

Preventive Measures for Eye Protection in Welding

Use Welding Curtains or Blocks

To safeguard your eyes while welding, there are several preventive measures you can take.
