First of all: why is looking at an eclipse dangerous for your eyes? The sun is BRIGHT. Our eyes evolved to see things using the small fraction of the sun's light that is scattered by a given object and reaches our eyes, which makes the sun painful to watch directly. 2/

Furthermore the sun is far away, which means that the rays of light arrive to us almost perfectly parallel to each other, which means that the lens in our eyes will make an amazing job at focusing that light into a small spot on our retina. 3/

High brightness + small spot = your retina will burn and get scarred. Not fun. To make things worse, during the full eclipse there is a short time when the sun is fully obscured, and thus you don't need any protection to see the beautiful corona around it. 4/
