Question

Quizplus · Accepted Answer

The blind spot of the eye is caused by the absence of photoreceptors where the optic nerve leaves the eye. This is because the optic nerve bundle leaves the retina through a small hole called the optic disc, which has no rods or cones. Therefore, light that falls on this part of the retina cannot be detected by the photoreceptors and is not seen.
