The first benefit many will notice is how they actually help to improve visibility. They tend to be at the highest shade, ranging from ratings 9 to 14, but even so, they still offer the best optical clarity for heavy-duty welding work. 

Another major benefit of gold-coated welding lenses is that they can reduce eye strain over long-term usage, which leads to reduced fatigue as well. That means you can weld in a focused state and not make mistakes or damage items through your welding work. 

With gold lens welding options, you actually have protection against three different types of radiation that can occur during welding activities. It also helps to reduce the reflection of infrared radiation by 90%, which reduces heat exposure as well. That’s a big advantage of gold welding lens equipment, as the other lens types won’t help reduce the scorching heat in welding activities. 

If you go with green or alloweld lenses for welding, they will protect your eyes, but they will have a much lower shade rating, meaning that things such as glare can become an issue. Some may opt for cobalt blue lenses, but those are less for working and more for observing the work being done.
