The Region of Sharpest Vision is the _______

Question

The region of sharpest vision is the _______.
A) optic disk
B) optic chiasm
C) fovea
D) pupil

Accepted Answer

The fovea is a small, central region in the retina where cone cells are densely packed, leading to the sharpest and most detailed vision. The optic disk is the point where the optic nerve exits the eye, containing no photoreceptor cells and resulting in a blind spot. The optic chiasm is where the optic nerves from each eye cross over, but it is not associated with sharp vision. The pupil is the opening in the center of the iris that regulates the amount of light entering the eye, but it is not a region of vision.
