What Is a Schematic: Meaning, Uses, and How to Read One

A schematic is a diagram that shows how the parts of a system connect and relate to each other, using simple lines and standardized symbols instead of realistic pictures.

Schematic overview of (A) emmetropia and (B) myopia. In

In emmetropia, the optics of the eye focus light rays entering the eye exactly on the retina. In myopia, the ocular globe is elongated, and the light rays are focused in front of the retina.
