Many people enjoy watching welding videos on YouTube. But some wonder, is it safe to watch them? Welding looks bright and strong. It uses light that can hurt your eyes. So, this question is important. Let’s explore the facts.
What Happens When You Weld?
Welding uses a strong light called an electric arc. This light is very bright and has ultraviolet (UV) rays. These rays can harm your eyes and skin if you see them directly. Welders wear special helmets to protect themselves.
If you look at a welding arc without protection, you might get a painful condition called arc eye or welders flash. It feels like having sand in your eyes. It can also cause redness and watering.
Can Welding Videos on YouTube Hurt Your Eyes?
Many people ask if watching welding videos on YouTube is dangerous. The quick answer is no. Watching videos of welding will not hurt your eyes.
Here is why:
- UV rays do not pass through cameras. Cameras and phones cannot capture UV light.
- Screen lights are safe. The light from your phone or computer screen does not have harmful UV rays.
- Videos show only visible light. Your screen shows only the light the camera records, which is safe.
So, the strong UV light from welding does not reach your eyes through videos. You are safe while watching welding on YouTube.

Why Does Welding Look So Bright on Video?
Welding videos can be very bright and sometimes flashy. This is because the welding arc is a strong light source. But the camera changes how this light looks.
Sometimes, the camera cannot capture the full brightness of the arc. This can cause the video to look overexposed or have bright flashes. Some video makers try to reduce these flashes to make the video easier to watch.
Can Watching Welding Videos Cause Eye Strain?
Even if welding videos do not give you arc eye, they might cause eye strain. Eye strain happens when you look at bright or flashing lights for a long time.
Watching any bright video for many hours can make your eyes tired. You might feel discomfort or headache. To avoid this, follow simple tips:
- Take breaks often. Look away from the screen every 20 minutes.
- Use good lighting in the room. Avoid watching in the dark.
- Adjust your screen brightness to a comfortable level.
Is It Safe to Record Welding Videos?
Some people record their welding work with phones or cameras. This can be safe if done carefully.
But there are some risks:
- Camera damage. Sparks and hot metal pieces can harm your device.
- Lens damage. The bright light can sometimes hurt camera sensors.
To protect your device, keep it at a safe distance. Use a cover or case if possible. Avoid pointing the camera too close to the arc.
What Do Experts Say?
Experts and welders agree that watching welding videos is safe. The UV light from welding cannot pass through cameras or screens.
Many welders post videos online to teach others. They also use filters and special settings to reduce glare in videos.
Some people worry about “welders flash” from video. This worry is not needed because the harmful rays cannot reach you through your screen.
The Science Behind the Safety
1. The Physics of Camera Sensors (The UV Filter)
Modern digital cameras are designed with internal UV and IR (Infrared) cut-off filters. Because camera sensors are naturally sensitive to light humans can’t see, manufacturers place a physical filter over the sensor to block UV rays so the photo looks natural.
- Scientific Fact: Silicon-based sensors (CMOS/CCD) are sensitive to the 190–1100 nm range, but the filter blocks everything below ~400 nm (UV).
- Source Citation: Ray, S. (2002). Scientific Photography and Applied Imaging. This text explains how optical filters are mandatory in digital imaging to prevent UV fogging and sensor damage.
2. The Mechanics of LED/LCD Screens
A computer screen cannot “recreate” a UV ray because of how it produces light. Screens use RGB (Red, Green, Blue) sub-pixels. These sub-pixels are tuned to specific wavelengths of visible light.
- Scientific Fact: The light-emitting diodes (LEDs) or liquid crystals in a screen simply do not have the physical capability to vibrate at the high frequency required to produce Ultraviolet (UV) radiation ($<400\text{ nm}$).
- Source Citation: International Commission on Non-Ionizing Radiation Protection (ICNIRP). They provide guidelines showing that electronic displays do not emit hazardous levels of UV or ionizing radiation.
3. Photokeratitis (Arc Eye) Requirements
“Arc eye” is essentially a sunburn on the cornea. It requires high-energy photons found in the UV-B and UV-C spectrum.
- Scientific Fact: Photokeratitis ($E_{eff}$) is caused by radiation in the 180 nm to 315 nm range.
- Source Citation: American Conference of Governmental Industrial Hygienists (ACGIH). Their “Threshold Limit Values” for physical agents confirm that this damage only occurs from direct source exposure, not reproduced imagery.
How to Enjoy Welding Videos Safely
Here are some easy steps to watch welding videos without problems:
| Tip | Why It Helps |
|---|---|
| Watch from a comfortable distance | Reduces eye strain and discomfort |
| Take regular breaks | Rest your eyes often to avoid tiredness |
| Use moderate screen brightness | Prevents harsh light on your eyes |
| Watch in a well-lit room | Prevents eye strain caused by contrast |
| Do not watch while very tired | Helps keep your eyes healthy |
When to Avoid Watching Welding Videos
Most people can watch welding videos safely. But some should be careful. If you have sensitive eyes or eye problems, avoid watching bright or flashing videos.
If you feel pain or discomfort after watching, stop and rest your eyes. If problems continue, see an eye doctor.
Frequently Asked Questions
Is It Safe To Watch Welding Videos?
Watching welding videos is safe because screens cannot emit harmful UV rays from welding arcs. Your eyes stay protected.
Can You Get Welders Flash Through A Video?
You cannot get welder’s flash from watching welding videos. Screens do not emit harmful UV rays that cause eye damage. Welding flash requires direct exposure to intense UV light, which videos and phone screens cannot reproduce. Watching welding videos is safe for your eyes.
How Far Away Is It Safe To Watch Welding?
Maintain at least 10 feet distance to safely watch welding. Always wear proper eye protection to prevent UV damage and arc flash injuries. Direct exposure to welding arcs without protection can cause serious eye harm. Never look directly at welding without a certified welding helmet or goggles.
Is It Bad For A Camera To Video Welding?
Filming welding can damage cameras due to intense brightness and sparks. Use protective filters and keep distance to avoid harm.
Conclusion
Is it safe to watch welding videos on YouTube? Yes, it is safe. The harmful UV rays from welding do not come through video screens.
But be careful of eye strain from bright and flashing images. Use good watching habits. Take breaks and protect your eyes.
