Also, a welder's goggles used in arc-welding with one of the darker filters can be used to look at the sun and maybe see one of the larger sunspots. Don't try this with the weaker filters found in cutting torch goggles. Or if you try it anyway, the black spots [a different kind of sunspot] in front of your eyes for the rest of the day or the rest of your life will be a sign that you should remember that somebody said to not do that.

I've tried that when I worked for a company that made safety equipment.
We used the welders lenses when there was an eclipse. Not since then, tho!
