Gives you the clearest and sharpest picture of an image we are viewing.
The fovea centralis. It is the area of sharpest vision because it contains the highest proportion of cones with almost no rods.
The fovea centralis, also generally known as the fovea, is a part of the eye, located in the center of the macula region of the retina. It's important because it's the center of the eye's sharpest vision and the location of most color perception.
It actually depends on the lens. For the image to be sharp on the retina, all the rays of light coming off the object must meet together at the same point on the retina. If the rays of light meet somewhere in front of the retina, the lens focuses by stretching itself and becoming thinner. This spreads out the rays of light, making them go further into the eye until they reach the middle of the retina. If the rays of light are behind the retina, the lens thickens to focus.
Obsidian fragments are known to have some of the sharpest edges possible.
The sharpest vision belongs to the birds of prey especially eagles and hawks
the fovea centralis is the point of clearest vision

Fovea centralis
The fovea gives you the clearest and sharpest image of the item of thing we are viewing it is necessary for many things such as driving or watching TV
Macula Lutea
It's like looking through a pinhole.
Fovea centralis at the Macula. it is so because it contains receptor cells known as the Rods & Cones.Fovea centralis

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.
Cells in the the retina called cones (for colour perception and in greatest numbers in the macula) and rods (for black and white).
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.
