The abbreviation that means "both eyes" is "O.U." This is derived from the Latin phrase "oculus uterque," which translates directly to "each eye" or "both eyes." In a medical context, it is commonly used in prescriptions or instructions regarding eye medications or treatments, indicating that the medication should be applied or taken for both eyes.

Understanding abbreviations in the medical field is crucial, especially for medication aides who may need to follow these instructions accurately to ensure patient safety and the effectiveness of treatment. Recognizing that "O.D." refers to the right eye ("oculus dexter"), "O.S." refers to the left eye ("oculus sinister"), and "NPO" means "nothing by mouth," helps in preventing any miscommunication when dealing with patient care and medication administration.
