Hey guys, I tried searching but no luck. Can I use my 190-540, 800-2000nm goggles OD 4 for eclipse viewing? Partial eclipse where I am? I'm guessing not, I ordered some cheap NASA certified ones.
I want to view it directly. I'm not looking for alternative solutions, I already know those. I'm just wondering if what I proposed would or would not work.
I have seen paper googles advertised on Amazon for viewing the eclipse. I don't know anything about them, but you'd think they are safe if advertised as being so. I used the pin hole trick for viewing a solar eclipse back in the early 1990s and it worked well.
Ok, here's some answers.
Don't use Laser goggles.
Just like we discourage noobs from using welder's goggles for lasers.
Don't risk using laser goggles,
not suitable for an eclipse.
On the other hand, welders goggles
are suitable for a solar eclipse.
Make sure they're rated at 14, Green Shade.
Quote from a welder website.
#14 is the darkest lens shade you can buy – just as dark as the most protective welding helmet shades. As a result, these glasses are so dark that you can wear them to watch a solar eclipse, as well as using them for all types of welding including MIG and TIG. The glass lenses, which have been made to a high quality, block out almost 100% of UV light and 97% of infrared radiation, giving your eyes almost complete protection.
The cheapest way is to buy reputable NASA shades like the ones you ordered.
Simple, cheep but high quality.
Good luck and clear skies (you lucky ducks...
