That image is from 1961 and an idealization. Here is an actual trajectory of fixational eye movements. The dots are 2 ms apart. If a midget ganglion cell, with single-cone receptive field, fires at 100 Hz, then every spike reports about a different cone. How can we ever read anything?

This is the ganglion cell layer of the avian retina. The nerve fiber layer lies beneath like a soft green current, carrying quiet signals forward.
Sometimes to see the universe with its beautiful scattered stars, one only has to look inside.

In the retina, amacrine cells boost contrast by silencing nearby signals, helping your brain detect edges and details. Retinal ganglion cells then send that refined picture to your brain through the optic nerve.
