   Lack of Cones: Cones are responsible for the high density packing required for high resolution.
   Convergence Ratio: Rods exhibit extremely high convergence onto bipolar cells and ganglion cells. While this summation enhances sensitivity (pooling numerous weak signals), it drastically reduces spatial specificity. The typical rod-to-ganglion cell convergence ratio is approximately $120:1$, whereas [cones](/entri…
