Which retina region contains more cones, nasal or temporal retina, and by approximately what percentage?

Explanation:
Cone distribution across the retina isn't uniform. While the fovea holds the highest density of cones for peak, center-field vision, the surrounding regions also show patterns in how many cones are present. In particular, the nasal retina has more cones than the temporal retina, by about 25%. This means that, at comparable distances from the fovea, the nasal side provides slightly higher cone density, which supports fairly tight, color-rich vision in that part of the retina.
