Understanding OU in Eye Prescriptions
OU is an abbreviation used in optometry and ophthalmology, commonly found on prescriptions for eyeglasses or contact lenses. It is derived from the Latin term "oculus uterque," which directly translates to "both eyes." This abbreviation indicates that the prescription applies to both eyes simultaneously.
Abbreviation | Meaning | Latin Origin |
---|---|---|
OU | Both Eyes | Oculus Uterque |
OD | Right Eye | Oculus Dexter |
OS | Left Eye | Oculus Sinister |
Example:
If your prescription shows the same values for OU, it signifies that both eyes require the same correction.
