I don't think his statement "bright light can never hurt your eyes" is correct, and I think "I got behind a truck windshield, because the ultraviolet can't go through glass, so that would be safe" is pretty questionable: glass filters ultraviolet, but I don't think it blocks it completely. But fact is: Feynman looked at an atomic explosion and he wasn't blinded.
