Cone density is highest in the foveola at about 200,000 cones/mm^2. As you move outward, does the concentration increase or decrease?

Explanation:
Cone density peaks in the foveola because that central region is specialized for high-acuity vision, with a very dense packing of cones. As you move outward from the foveola, the cones become less tightly packed, so the number of cones per square millimeter decreases. This lower sampling density means lower spatial resolution in the peripheral retina. Rods, which are not concentrated in the fovea, become more prominent outwardly, boosting sensitivity in dim light but not restoring high acuity. So, the concentration of cones decreases as you move away from the foveola.
