Vedclass · Answer

(C) The optic nerves leave the eye and the retinal blood vessels enter it at a point medial to and slightly above the posterior pole of the eyeball.Photoreceptor cells (rods and cones) are not present in this specific region,and therefore,no image is formed here,which is why it is called the blind spot.In contrast,at the posterior pole of the eye,lateral to the blind spot,there is a yellowish pigmented spot called the macula lutea with a central pit called the fovea.The fovea is a thinned-out portion of the retina where only the cones are densely packed,providing the greatest visual acuity.
