In terms of visual impairments, which term refers to both eyes?

The term that refers to both eyes is "OU," which stands for "oculus uterque" in Latin. This designation is commonly used in the field of optometry and ophthalmology to indicate assessments or prescriptions that apply to both the left and right eyes.

Understanding this terminology is important for vision professionals as it ensures clarity when discussing visual assessments, treatments, or procedures that involve both eyes. For example, if a patient needs glasses for both eyes, the prescription would indicate OU to signify that the correction applies universally to both the left and right eye.

The other terms are specific to one eye: "OD" refers to the right eye (oculus dexter), and "OS" refers to the left eye (oculus sinister). "MD" typically refers to a medical doctor and is not relevant in this context of visual impairments.
