Caution: retina burns painlessly

[Interplanner]

There is no pain when the retina burns, so read all the instructions carefully! DON'T look at partiality. Only look (unassisted) at totality while it lasts.

There aren't any nerve signals that come from the retina.

I view eclipses by punching a pin hole in a piece of paper and letting it shine on a white surface. Saves the eyes.

Yes, and then I found that there is a natural version of that, which today was called 'happy face' images. Under trees with heavy foliage, there are just small rays of sunlight that get through. The crescent images they make on the ground or walls of buildings are exact images of what's going on up there!
