Question

In eye, fovea is the center of the visual field, where:

• A. high density of rods occur
• B. high density of cones occur
• C. the optic nerve leaves the eye
• D. only rods are present

Answer 1

The correct option is B

high density of cones occur

Fovea is a spot in the retina where images are focused. It has a high density of cones but has no rods. The fovea permits detailed vision. Blind spot is the point in the retina where the optic nerve exits the eye. There are no photoreceptors which makes this blind spot insensitive to light.
