Quizplus · Accepted Answer

The fovea is the part of the retina that contains the highest concentration of cones, which are photoreceptors that are responsible for color vision and visual acuity. The optic disc is the point where the optic nerve leaves the eye and does not contain any photoreceptors. The optic nerve is a bundle of nerve fibers that carry visual information from the eye to the brain. The sclera is the tough, outer layer that forms the white of the eye and does not contain any photoreceptors.
