The fovea works because your brain creates images from points.

Explanation:

The fovea is located in the center of the eye's retina. It is the structure capable of capturing stitches from what you are viewing and sending those stitches to the brain, which will "stitch" all stitches together and form an image. In summary, the fovea is able to project an image to the brain through pieces of the image, it is formed by cones that allow the transmission of light to the photoreceptors of the eyes.
