The macula is indeed the most sensitive part of the retina, specifically designed for detailed and central vision. It contains a high concentration of photoreceptor cells, particularly cones, which are essential for seeing fine details and color discrimination. This area allows for tasks that require visual acuity, such as reading, driving, and recognizing faces. Its structure and function are adapted to provide the clearest vision possible, making it a critical component of the visual system.

In contrast to the macula, peripheral vision is governed by other areas of the retina, which are more sensitive to motion but not to fine detail. Low-light vision, primarily managed by rods found in the peripheral regions of the retina, does not occur in the macula, as this region is not effective in dim lighting conditions. Similarly, the layer responsible for nourishing the eye is the choroid, which lies beneath the retina and provides vital nutrients but is distinct from the functionalities provided by the macula.
