OS stands for which in eye terminology?

Explanation:
OS is the shorthand for oculus sinister, the Latin term for the left eye. In eye terminology, physicians use Latin abbreviations to quickly indicate which eye is being referred to: OD means oculus dexter (right eye), OU means oculus uterque (both eyes), and OS points to the left eye. The word “oculus” means eye, “sinister” means left, while “dexter” means right, and “uterque” means both. So OS specifically indicates the left eye.
