Is It Safe to View an Eclipse or the Sun with a Welding Mask?Yes, you can use a welding mask to safely look at both the sun and an eclipse, but only if the mask has a shade of 12 or higher. A mask with a shade lower than 12 won't provide sufficient protection for your eyes, and many readily available welding masks in stores typically don’t meet this level.

Can a welding mask protect your eyes while watching an eclipse?
Is It Safe to View an Eclipse or the Sun with a Welding Mask?
Yes, you can use a welding mask to safely look at both the sun and an eclipse, but only if the mask has a shade of 12 or higher. A mask with a shade lower than 12 won't provide sufficient protection for your eyes, and many readily available welding masks in stores typically don’t meet this level.
Looking directly at the sun or an eclipse can cause irreversible damage to your eyes. Prolonged exposure can lead to blindness or permanent vision issues.
Protecting your eyes from solar events is crucial. Continue reading to learn how to properly use welding masks for this purpose.
How Do Welding Masks Safeguard Your Eyes?
A welding mask provides full face coverage and features a tinted window at the front, allowing you to see your work. The level of tint on the window is determined by the amount of ultraviolet (UV) or infrared light that needs to be filtered out.
These harmful UV and infrared rays are emitted during the heat reaction with metal, and the intensity varies depending on the type of metal being welded.
Many people choose helmets with the darkest tint, as it offers versatile protection for a wide range of projects and metals.
Welding masks are highly effective because they provide full facial coverage. They can be worn over regular eyeglasses and tend to stay in place better than standard sunglasses.
As long as the mask is free of cracks or scratches and the shade is dark enough, your eyes will be fully shielded from harmful UV rays.
The lenses in welding masks are specifically designed to filter out UV light by darkening the glass. While it’s impossible to block all UV light, they filter enough to protect your eyes from intense UV exposure.
The lowest shade, a 2, offers minimal protection and is only suitable for torch soldering. It’s not adequate for welding or direct sunlight and could cause serious harm if used for other tasks.
In contrast, a shade 14 mask, the darkest available, provides nearly complete protection from UV rays, no matter what you're looking at.
Note: If you plan to use a welding mask to view the sun, NASA recommends using a dedicated solar filter designed for safe sun gazing. This filter offers the highest level of UV protection for your eyes.
Is It Safe to Look at the Sun with a Welding Helmet?
While it may be technically possible, it's highly discouraged to attempt looking at the sun through a welding helmet. Solar eclipse glasses are specially designed to offer superior eye protection, far beyond the limited tinting of welding helmets.
Given the serious risks of temporary blindness or more severe damage, it's not a matter to take lightly.
But from a technical standpoint, can you do it?
The answer is yes, but with significant caution. First, ensure the helmet fits securely on your head. Even a slight shift could expose your eyes to harmful rays, potentially causing irreversible damage.
Only welding helmets with a darkness rating of 12 or higher offer any semblance of protection against the sun's rays.
While NASA strongly recommends using proper solar eclipse glasses, in theory, welding helmets with the darkest settings might allow for safe sun viewing, though it's still not advisable.
