(N/A) - The $blind \ spot$ is a small area on the retina where the optic nerve exits the eye. Photoreceptor cells (rods and cones) are absent in this region,so no image is formed here.
- The $fovea$ is a central pit located within the $macula \ lutea$,a yellowish pigmented spot found at the posterior pole of the eye,lateral to the blind spot. It contains a high density of cones and is responsible for the sharpest visual acuity.
