Cones
Photoreceptor cells in the retina that enable color vision and visual clarity in bright light.
Fovea Centralis
A small depression in the retina of the eye where visual acuity is highest, due to the concentration of cones, specialized for daylight vision, fine detail, and color.
Retina
The light-sensitive layer of tissue at the back of the inner eye that converts light into electrical signals sent to the brain, allowing for vision.
