Interaction of light with visual pigments transforms their molecules and

excites rods and cones
Pigment xanthophyll accumulates in ganglion cells of macula lutea
Fovea is in the center of macula lutea and devoid of rods and blood vessels
Fovea contains a high concentration of the photosensitive cones
Fovea produces greatest visual acuity and sharpest color discrimination

Blood vessels do not pass over fovea region in the retina
