WebbHumans perceive purple as a range of color that falls between blue and red on the visible light spectrum. Our brains interpret the wavelengths of light that fall within the range of approximately 380 to 450 nanometers as purple. To fully understand perception of purple, it is important to understand how the human eye works. WebbLocation: Cones are highly concentrated in the fovea centralis, whereas rods are highly concentrated in the peripheral region of the retina..

"WebbThe humans’ eyes are both set on the front of the face, permitting binocular vision. Each eye has a field of view, which is the area that an individual can see when one closes an eye. The center of the eyes’ fields of view overlaps with one another, although visual information in the periphery can only be detected by one eye. " - The photopigment rhodopsin is found in

The optic nerve is mainly made up of the axons (nerve fibers) of the retinal ganglion cells from the retina. The optic disc or nerve head is the point where the axons from the retinal ganglion cells leave the eye. The nerve head appears as a white circular structure in the back of the eye. There are no photoreceptors on this structure.
