How about stick welding mask?
That what I have used in the past. One time I even stacked up about 8 pairs of sunglasses and that worked fine also.
That or torch goggles?
I really don’t care about the eclipse thing that much. I’ll go outside with the rest of the herd and not look at the sun.
It’d be funny if it clouded up or rained.
Shade 14 or darker should be good.

I’ve heard that shade 14 welding glasses should be okay. Probably a lot better than the cheapo cardboard glasses so many are selling.
