The area of sharpest vision in the eye is called the fovea. It is located in the center of the retina and contains a high concentration of cone cells, which are responsible for color vision and detailed central vision.
The fovea centralis is the area of sharpest vision in the eye. It is located at the center of the retina and contains a high concentration of cones, which are responsible for color vision and detailed focus.
Macula Lutea
Our sharpest, clearest vision is referred to as "visual acuity." This term describes the eye's ability to discern fine details and is typically measured using an eye chart. Visual acuity is crucial for tasks requiring precise vision, such as reading or recognizing faces. It is often expressed as a fraction, with 20/20 vision being considered normal.

The Fovea Centralis is a small pit located laterally to the optic disk and is the area of sharpest vision that is located in the center of the macula lutea.
The sharpest vision on the retina is in the central area. That is where most of the cones are concentrated that have the best detail resolution and respond better when light levels are higher in bright light. There are more rods towards the periphery of the retina. Though they are less able to distinguish detail, they are better at detecting motion and are sensitive at low light levels.
