Where does the S-cone density peak occur in the retina?

Explanation:
S-cones, the blue-sensitive cones, are sparse right at the fovea because this area is dominated by L- and M-cones to support high-acuity daylight color vision. As you move slightly away from the fovea into the parafovea, S-cones become more numerous and their density reaches a peak around 0.5 degrees of eccentricity. Past that point, their density declines with increasing eccentricity. So the location where S-cone density is highest is about 0.5 degrees from the fovea.
