32.The image on the retina is reversed upside down and backwards because of bending of light rays.
33.A concave lens is used to correct for a myopic eye.
34.Retinal is derived from vitamin A and is found in rods but not the cones.
35.Rods produce vision in shades of gray.
36.Vision in bright light is chiefly due to cone activation.
37.Cone photoreceptors provide high visual acuity.
38.When an individual sees pure green, only the green cones are stimulated.
39.In the retina, photoreceptor cells do not release neurotransmitter onto ganglion cells.
40.Light must pass through several layers of retinal cells before reaching rods and cones.
