Answer:
Answer:
Anatomically this is because there are no neurons or blood vessels covering the cones.
Explanation:
Fovea centralis and its containing cones cell is surrounded by the macula lutea to form a depression or pit in the retina. The abundant cones cells provide high visual acuity characteristic of the fovea.
In addition an area in the fovea of no blood cells called fovea avascular zone allows light rays to be focused on the fovea, with less scattering,this minimises the losses of incident lights on the fovea, and therefore reception of maximum light rays from objects for acute vision.
Therefore the presence of abundant cones cells in the fovea together with the presence of fovea avascular (area with no blood cells)which reduces dispersion of light rays for maximum receptions are responsible for high visual acuity of the fovea.
This explains the reasons why fovea is refereed to as the center for primary vision or fovea vision where high degree of visual activity is needed such as focusing with microscope, reading,knitting and driving
