Final answer:
The fovea is the region in the center back of the eye that is responsible for acute vision. It has a high density of cones and provides the greatest visual acuity.
Step-by-step explanation:
The fovea is the region in the center back of the eye that is responsible for acute vision. The fovea has a high density of cones, which are specialized photoreceptor cells that work best in bright light conditions. Visual acuity, or the sharpness of vision, is greatest at the fovea because it lacks supporting cells and blood vessels that might absorb incoming light.
