Macula Lutea
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.
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.
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.
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.
The sharpest vision belongs to the birds of prey especially eagles and hawks
The small depression of the retina at the back of the eye is called the fovea. It is responsible for sharp central vision and contains a high density of cones, which are responsible for color vision and detecting fine details.

The retina is the part of the eye that contains light receptors called rods and cones. These receptors are responsible for detecting light and translating it into electrical signals that are sent to the brain for processing.
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.
No, currently there is no proven method for a retina transplant to improve vision.
Fovea centralis - contains only cones and maximal visual acuity
