fovea

This spot in the retina that is responsible for the exact center of our vision.  The retina works like film in a camera and detects light. The most important part of the retina is the macula, which corresponds to our central vision.  In the exact center of our macula is a small depression in the retina called the fovea. This is the most sensitive part of the entire retina and corresponds to your extreme central vision.  For example, if you closely examine the period printed at the end of this sentence, the light bouncing off that period is focused directly onto your fovea. On a day-to-day basis, most eye doctors don’t talk about the fovea but discuss the larger macular area in general. The fovea is more of an anatomical landmark seen on retinal scans like the OCT or fluorescein angiogram.
