The point on the retina where the optic nerve leaves the eye has no photoreceptor cells. What is this point called?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Blind spot
Where the optic nerve leaves the eye, there are no rods or cones, so an image falling there is not seen. This point is the blind spot; the fovea, by contrast, is the point of sharpest vision.
