What is the area of the eye with the greatest acuity?
A) fovea
B) macula lutea
C) optic disk
D) lens
Fovea
A tiny indent in the eye's retina where vision is the sharpest.
Macula Lutea
A small, yellowish central area of the retina that is rich in cones and where visual acuity (sharpness) is highest.
Optic Disk
The point in the eye where the optic nerve enters the retina, often referred to as the blind spot since it lacks photoreceptors.
- Identify the regions of the eye associated with the highest visual acuity.

Final Answer :
A
Explanation :
The fovea is the area of the retina that contains the highest concentration of cone cells, which are responsible for color vision and visual acuity. Therefore, the fovea has the greatest acuity of all the areas in the eye. The macula lutea is located near the fovea and also contains a high concentration of cones, but the fovea itself has the highest acuity. The optic disk is the area where the optic nerve exits the eye and does not contain any photoreceptor cells, so it is not involved in visual acuity. The lens helps to focus light onto the retina, but does not have any photoreceptor cells and is not directly involved in visual acuity.
