The central section of the retina, known as the macula, is in charge of our main vision and permits us to see fine details and also shades.
Surrounding the retina is the choroid, a vascular layer that offers oxygen and nutrients to support its function. The choroid additionally has pigment cells that aid take in excess light, improving aesthetic quality.
