Absolutely, I know it's not just a myth. It's just that whether you need eclipse glasses is more nuanced than "always wear them." If you're going to stare at an eclipse for multiple seconds on a cloudless day you're probably going to be in for a world of hurt.
Staring at the Sun is bad, no matter when you do it. The Sun emits no extra photons during an eclipse. Your pupils do expand due to physiological responses of the decreased light, however.
In San Francisco the eclipse was only partial and behind a cloud of fog. In that case looking at it's no worse than looking at the sun behind a cloud on a non-eclipse day.
