|
contains most of the photoreceptors on the retina

is the point where there is an intense concentration of rods on the retina
|
|
|
contains the pigment which provides “eye colour” and controls the amount of light entering the eye
|
|
|
is the point where there is an intense concentration of cones on the retina

Detailed explanation-1: -The fovea is a depression in the inner retinal surface, about 1.5 mm wide, the photoreceptor layer of which is entirely cones and which is specialized for maximum visual acuity. Within the fovea is a region of 0.5mm diameter called the foveal avascular zone (an area without any blood vessels).
Detailed explanation-2: -The foveal center or ‘foveola’ contains the highest density of cone photoreceptors in the retina. Cone photoreceptors function in bright light and support high acuity and color vision.
Detailed explanation-3: -The center of the macula is called the fovea. This area has the greatest concentration of cones and is responsible for most of our fine detailed vision.
Detailed explanation-4: -The macula lutea, also called fovea, contains a very high concentration of cones. These are the light-sensitive cells in the retina that give detailed central vision.
Detailed explanation-5: -the cones are concentrated in the fovea, whereas the rods predominate in the peripheral retina. there is low convergence of foveal cones onto macular bipolar cells, as low as one cone receptor to one bipolar cell.
