Embarrassing #question about vision and #biology of the human #eye: How does light get to rods & cones past all the stuff in the way?
I'm not really a "bio person" so I only have a basic understanding of how the retina is composed of photoreceptors, bipolar cells, ganglion cells, and amacrine cells. I understand, at least on this level, how rods and cones send action potentials to bipolar (and maybe amacrine) cells, how those send to gangion cells, and where the optic nerve leads next.
But all those bipolar, amacrine, and ganglion cells seem to be stacked between the photoreceptors and the light they respond to. The photoreceptors, as I understand it, are on the anterior (?) surface of the retina, farthest from the lens and pupil. It seems like there should be problems with the light getting past or through those other cells to activate rods and cones.
How does that work?
