Final answer:
In both the fovea and peripheral retina, the overlying bipolar and ganglion cells are pushed to one side, allowing light to strike the photoreceptors without passing through several layers of neurons. This is where vision is sharpest.
Step-by-step explanation:
The overlying bipolar and ganglion cells are pushed to one side in both the fovea and peripheral retina. This allows light to strike the photoreceptors without passing through several layers of neurons, making vision sharpest in these areas.
The fovea, located at the center of the retina, lacks supporting cells and blood vessels, containing only photoreceptors. On the other hand, the peripheral retina has denser cones and bipolar cells.
