A question about basic eye biology is circulating online: how does light reach the rods and cones at the back of the retina when other cells sit in front of them? The person asking admits limited biology knowledge but understands the retina contains photoreceptors, bipolar cells and ganglion cells. The discussion highlights a genuine anatomical oddity of the vertebrate eye, where light passes through several neural layers before hitting photoreceptors.
Why now: People find the seemingly 'backwards' wiring of the human retina a fascinating and counterintuitive bit of biology worth explaining.
