What region of the retina is responsible for high visual acuity and colour vision?

The fovea is the region of the retina that is responsible for high visual acuity and color vision. It is a small, central pit located within the macula lutea of the retina. The fovea contains a high density of cones, which are the photoreceptors sensitive to color and detail. This concentration of cones allows for sharp central vision and the ability to perceive fine detail, which is essential for tasks such as reading and recognizing faces.

In contrast, the anatomical blind spot, which is found at the optic disc where the optic nerve leaves the eye, does not contain photoreceptors. The peripheral retina, on the other hand, is primarily responsible for peripheral vision and motion detection but lacks the high concentration of cones found in the fovea, making it less effective at discerning color and detail. Therefore, the fovea plays a crucial role in tasks that require high visual acuity and color discrimination, and that is why it is the correct answer to the question.
