Which term represents 'both eyes' in prescription language?

The term that represents 'both eyes' in prescription language is commonly denoted as "ou," which stands for "oculi uterque" in Latin. This designation is used when a medication or treatment is intended to be applied to both eyes simultaneously.

In the context of ophthalmic prescriptions, it is important to differentiate between terms associated with each eye. "Od" refers to the right eye (oculus dexter), while "os" refers to the left eye (oculus sinister). Therefore, the term that specifies treatment for both eyes together is distinctly "ou," making it crucial for pharmacists and healthcare providers to recognize this terminology to ensure appropriate medication administration and patient care.

This distinction helps ensure clarity when dispensing medications, as miscommunication could lead to incorrect dosages or applications affecting only one eye instead of both.
