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

1. the optic nerve leaves the eye
2. only rods are present
3. more rods than cones are found
4. high density of cones occur, but has no rods

Correct answer: high density of cones occur, but has no rods

Solution

The fovea is the central retinal area responsible for the sharpest vision, so it contains a very high density of cones. Rods are absent there, which helps maximize fine detail and color discrimination.
