ONLY 14 (or darker, do they make darker than 14?), and ONLY if it's in immaculate condition. Any scratch/imperfection can be trouble.
I would not use an auto darkening one, they don't respond fast enough, and once the sun is partially covered (when you're most likely to want to look) they might not respond at all.
People, just buy some eclipse glasses. I know I harped on a few days ago about only buying from certain companies (and I still will harp on that), but I'd rather you bought cheap Chinese glasses over welding masks of dubious condition.
Hell, they had eclipse glasses for sale at Lowes by my house this weekend, you don't even have to search around online, buy some locally!
