All cone cells contain photopigments within their many membrane disks. Each photopigment is made up of a certain opsin protein, specifically variations of photopsin in human cone cells, and a chromophore, such as retinal in humans. Three different kinds of photopsins respond to the short, medium, and long wavelengths of light.

The nano-cone structure's coating looks like a cone forest composed of nano-cones in size from 100 to 800 nm (Fig. 1 a).

Overall, rods outnumber cones by a ratio of 20:1 or greater in the retina. However, in the fovea, the cone density is the highest and is correlated with visual acuity. The probability that a photon will be absorbed by a cone is based on three factors in temporal order: Growth cones are the specialized motile structure at the growing tips of developing and regenerating axons and dendrites.
