It's incredibly tiny. As I understand it they etch individual pixels onto it, each of which can only receive light from a specific angle. As you make it larger and larger you can absorb more and more light at higher and higher resolutions, without dealing with lenses.
Although even lenses can do insane things like magnify individual cells to be human visible, or take pictures of distant galaxies. I don't know why everyone is so skeptical of merely photographing someone's eye.
