A closeup of the Human Eye: literally eye opening!

Saw this on facebook, by Suren Manvelyan. Very cool!

Being able to SEE the muscle fibers that contract to open or close your iris… is pretty crazy.

Oh, fun fact – the human eye sees the world in a resolution of over 500 megapixels. I recommend watching the Cosmos reboot with Neil DeGrasse Tyson, as he actually explains how our eyes evolved. It’s fascinating!
