Eye doctors use diopters to measure prism ability or focal length in the correct eye (oculus dexter) and left eye (oculus sinister).
They then use that measurement to decide lens power and provide an eyeglass prescription.
Additionally, prescriptions include prism measurements, which are abbreviated for base up, base downward, base of operations in, or base out.
