A question about human eye biology is circulating online: how does light actually reach the rods and cones, given that retinal cells and other structures sit in front of the photoreceptors? The person asking admits to only a basic understanding of the retina's layered structure. It highlights the counterintuitive 'inverted' design of the vertebrate eye, where light must pass through several layers of neurons before hitting the photoreceptors.
Why now: The inverted structure of the human retina is a genuinely surprising fact that sparks curiosity whenever someone publicly asks how light gets through to the photoreceptors.
