All the sources I know of [e.g. 1] say there is no danger looking at the "sun" during 100% totality, and I have stared at the corona for minutes each of all three times I have been fortunate enough to experience totality and I appear to have no visual damage (actually have been tested for unrelated reasons). Of course it is dangerous to look at the sun during the build up to totality - but I recommend not looking up until the corona appears anyway (shadow bands and the onrushing shadow are more exciting than Bailey's Beads). If you have any reason to believe otherwise please share your sources. [1] https://eclipse.gsfc.nasa.gov/SEhelp/safety2.html https://eclipse.gsfc.nasa.gov/SEhelp/safety2.html

They're saying this was an annular eclipse, not a total eclipse. In my opinion that would be dangerous to stare at, and I'd suggest the burden of proof would be on you if you disagree.

  Yes, an annular eclipse is dangerous to look at at any time without protection. An annular eclipse by definition never reaches totality, since at maximum eclipse the sun is never 100% obscured. While the linked article discussed an annular eclipse, kobeya's comment makes it sound like looking directly at the sun during a total solar eclipse at toatlity is dangerous. This is wrong. It is not.
