This differs from tarsiers, which lack a tapetum lucidum but possess a fovea.

The fovea is the area of the retina where the sharpest central vision normally occurs.

The ability to perceive colour also declines rapidly away from the fovea.

The fovea itself can also be lens-shaped, increasing the effective density of receptors further.

Rods are distributed throughout the retina but there are none at the fovea and none at the blind spot.

Light travels from the fixation object to the fovea through an imaginary path called the visual axis.

Area consisting of a small depression in the retina containing cones and where vision is most acute
The fovea centralis, also generally known as the fovea (the term fovea comes from the Latin, meaning pit or pitfall), is a part of the eye, located in the center of the macula region of the retina.
The foveal system of the human eye is the only part of the retina that permits 100% visual acuity. The line-of-sight is a virtual line connecting the fovea with a fixation point in the outside world.
A slight depression or pit in a bone or organ; The retinal fovea, or fovea centralis, responsible for sharp central vision
The area of the eye in which the cones are concentrated.
A depression in the retina that contains only cones (not rods), and that provides acute eyesight.
(FOH-vee-uh). Central pit in the macula that produces sharpest vision. Contains a high concentration of cones and no retinal blood vessels.
The part of the retina in which the photoreceptive cells are most densely packed.
In the eye, the small, central region of the retina that exhibits the greatest sensitivity to detail and colour.
