Which term means both eyes?

Eye shorthand uses Latin abbreviations: OD stands for oculus dexter (right eye), OS stands for oculus sinister (left eye), and OU stands for oculus uterque (both eyes). The term that means both eyes is OU, used when a prescription or note applies to both eyes as a pair. OD and OS refer to a single eye each, so they don’t convey the idea of both eyes. None isn’t needed because there is a standard term for both eyes, OU. A quick tip: OU = both eyes, with uterque meaning “both.”
