How many cones are in the human retina?

Explanation:
Cones are the photoreceptors that support color vision and sharp central vision, and there are about 6 million of them in the human retina. They’re densely packed in the fovea, the small central area of the retina, which is why this region gives you high-acuity color vision. The retina also contains many more photoreceptors called rods—around 120 million—mostly in the peripheral retina, which are suited to low-light conditions but do not provide color or fine detail. So, for the number of cones, the typical figure is about 6 million.
