Will welding cause cataracts​?

Welding is very bright. If you work with welding tools, you may wonder if it can damage your eyes over time. The short answer is that welding can increase the risk if your eyes are not protected. However, with the right safety gear, the risk is much lower. In this blog, we explain what cataracts are, how welding affects the eyes, and how you can protect your vision.

What are cataracts?

A cataract is when the clear lens inside your eye becomes cloudy. The lens sits behind the coloured part of your eye. It helps focus light so you can see clearly. When the lens becomes cloudy, your vision may look blurry or foggy. Colours may seem dull. Lights may look too bright. Cataracts usually develop slowly over time. They are very common as we get older.

What causes cataracts?

The most common cause of cataracts is ageing. As we age, the natural lens inside the eye changes. It becomes less clear. Other things can increase the risk too. These include diabetes, smoking, long term sun exposure, eye injury, and certain medicines. Long term exposure to ultraviolet light, also known as UV light, can also play a part. This is where welding becomes important.

How does welding affect the eyes?

Welding produces a very strong light. It also gives off ultraviolet light. UV light is not always visible, but it can damage the eyes. If your eyes are exposed to UV light again and again over many years, this can increase the risk of cataracts. The risk depends on how often you weld, how many years you have done it, and whether you wear proper eye protection. Safety makes a big difference.

What is arc eye?

If you weld without protection, you can develop a painful condition called arc eye. Arc eye happens when UV light burns the surface of the eye. It can cause redness, pain, watery eyes, and strong sensitivity to light. Arc eye affects the outer layer of the eye. Cataracts are different. Cataracts affect the lens inside the eye and develop slowly over time. They are not caused by one short exposure, but by long term damage.

Can welding directly cause cataracts?

Welding does not cause cataracts overnight. Cataracts form slowly. However, long term exposure to UV light without proper eye protection can increase the risk. This is similar to spending many years in strong sunlight without wearing sunglasses. The damage builds up over time. If you always wear approved safety equipment, the risk is much lower.

Does wearing a welding helmet prevent cataracts?

Yes, wearing a proper welding helmet greatly reduces the risk. A welding helmet with the correct filter lens blocks harmful UV light. Modern helmets are designed to protect your eyes from both visible and invisible light damage. It is important that the helmet fits well and that the lens is not damaged. Never lift the helmet while the welding arc is active. Good safety habits protect your eyes for the future.

What are the signs of cataracts?

Cataracts often start slowly, so you may not notice changes at first. Over time, you may see blurred or cloudy vision. Bright lights may cause glare. You may notice halos around headlights at night. Colours may look faded. You may need brighter light to read. These changes usually happen little by little. If you notice these signs, it is important to have your eyes checked.

Are welders more at risk?

Welders who do not use proper protection are more at risk of UV damage. However, welders who follow safety rules and wear the correct helmets have a much lower risk. The key factor is protection. UV exposure over many years without protection increases the chance of cataracts. Safe practice helps protect your sight.

How do you know if welding has affected your eyes?

If you weld and notice changes in your vision, do not ignore them. Not all vision changes are cataracts. An eye exam can check your lens, retina, and overall eye health. Regular eye tests are important if you work in a job that exposes you to bright light. Early checks can spot problems before they affect daily life.

Can cataracts be treated?

Yes, cataracts can be treated with surgery. Cataract surgery removes the cloudy lens and replaces it with a clear artificial lens. It is one of the most common and successful procedures in the UK. Many people notice clearer and brighter vision soon after surgery. If cataracts begin to affect your work or driving, treatment can help restore vision.

Should welders have regular eye exams?

Yes, regular eye exams are very important for welders. Eye checks can monitor the clarity of your lens and detect early signs of cataracts. They can also check for other eye problems. Even if your vision feels fine, routine exams give peace of mind and help protect your long term eye health.

When should you seek advice?

You should seek advice if you notice blurred vision, increased glare, trouble driving at night, or changes in colour vision. These can be signs of cataracts. An assessment can confirm what is happening and explain your options. Early advice helps you plan ahead and protect your sight.
