Looking directly at the sun is unsafe except during the brief total phase of a solar eclipse, when the moon entirely blocks the sun's apparent disk. You have to be careful not to look at the sun in any other circumstances. During a total solar eclipse maximum phase, you can even look at it with binoculars, it's incredible. But you have to be aware of the time and stop staring at it when the end of the total phase approaches. A "thin outline of a circle" burn would probably occur if you have the bad idea of looking at an annular eclipse during the max phase, with binoculars and no protection. Having eye burn damage suck. Zero uplift.
