The macula

macula

The macula occupies the smallest surface in the eye, but one can say that it is crucial for our precise sight. Macule is small and very sensitive, and as a part of retina it is responsible for the central vision. Its diameter is about 5 mm. In the very center of macula are located the fovea and foveola which contain a high concentration of photoreceptors, that are very active when absorbing the light.

Macular function

The macula is in charge of the central vision during the process of observing details, figures/characters, while reading and writing.

It has been given that name “yellow dot” due to a high pigmentation (zeaxanthin and lutein), which is why it absorbs UV rays and blue rays. Its shape is oval and it’s situated in the very center of retina.
