Editing Macula (section)

==Function==
Structures in the macula are specialized for high-[[Visual acuity|acuity]] vision. Within the macula are the fovea and foveola that both contain a high density of [[Cone cell|cones]], which are nerve cells that are [[Photoreceptor cell|photoreceptors]] with high acuity.

In detail, the normal human eye contains three different types of cones, with different ranges of spectral sensitivity. The brain combines the signals from neighboring cones to distinguish different colors.  There is only one type of rod, but the rods are more sensitive than the cones, so in dim light, they are the dominant photoreceptors active, and without information provided by the separate spectral sensitivity of the cones it is impossible to discriminate colors.  In the fovea ''centralis'', cones predominate and are present at high density.  The macula is thus responsible for the central, high-resolution, color vision that is possible in good light; and this kind of vision is impaired if the macula is damaged, for example in [[macular degeneration]].<ref name="Macular Degeneration">{{cite web |url= https://www.lecturio.com/concepts/macular-degeneration/| title= Macular Degeneration
