We just learned about the Photoreceptor Cells.

Another part of the eye is the Fovea, sometimes called the fovea centralis, central fovea or fovea of the retina.
The word fovea just means a pit or a depression, and there are other parts of the body that have small pits so sometimes people have to say fovea centralis of the retina to make sure everyone knows which fovea they are talking about.

In the back of the eye by the macula on the retina is a small pit that is full of the cones we talked about.

This part of the eye is where the best sight comes from, when you are focused on looking at something while reading a book or driving a car.
