Which abbreviation represents the left eye?

The abbreviation that represents the left eye is "OS," which stands for "oculus sinister" in Latin. In medical terminology, this term is used to designate the left eye, distinguishing it from the other abbreviations that refer to different aspects related to vision.

The abbreviation "OD" means "oculus dexter," which refers to the right eye, while "OU" means "oculus uterque," indicating both eyes. "AX" does not relate to eye designations in this context, as it typically refers to an axis measurement in different settings, such as optics or anatomical terms.

Knowing these abbreviations is essential for correctly interpreting medical prescriptions, notes, and documentation related to eye care and optometry. Understanding what "OS" signifies helps healthcare providers ensure accurate communication regarding patient care involving the left eye.
