Fovea centralis
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.
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.
I have the sharpest eyes in my classroom.
The fovea centralis. It is the area of sharpest vision because it contains the highest proportion of cones with almost no rods.
The sharpest handsaws are made of highly tempered steel. The sharpest power saw blades are carbide tipped.
