What will happen if you stare at solar eclipse ?

1. Remember burning paper with lens using sunlight?

Solar Eclipse can do the same to your eyes

2. During partial eclipse, there's enough coverage of the intensity of the white light that other wavelengths particularly "red" (ie, heat) can be focused on our retina.

Solar radiation hits the retinas, triggers chemical reactions that damages photoreceptors

Thus cells that transmit images to the brain remain no longer functional.
