Near the inner surface of retina, there're many retinal ganglion cells which receive informations from photoreceptors (cones and rods).
So one weird thing about the human eye is that the receptor layer is actually behind the nerve cells that transmit the "data" from the receptors to the brain. According to (https://theconversation.com/look-your-eyes-are-wired-backwards-heres-why-38319#:~:text=The%20back%20of%20the%20retina,but%20which%20are%20colour%2Dblind.), this is because the nerve cells refract & guide the light to the receptors.
Reading the wikipidia articles on visual systems has been sooo cool: https://www.wikiwand.com/en/Visual_system! Apparently there are 5 different populations of ganglion cells responsible for depth, color, shape, and eye movements
