The fovea (also referred to as fovea centralis) refers to a tiny area of the eyes that rests within the macula.
The fovea is used to achieve an accurate level of vision for the direction in which this region has been pointed.
The foveal acuity makes reference to the depression in the retinal surface, which is highly specialized to achieve higher visual acuity.
