What is the correct abbreviation for left eye?

• A. OD
• B. OS
• C. OU
• D. LA

Answer: (B)

The abbreviation for the left eye is "OS," which stands for "oculus sinister" in Latin. In the terminology used in ophthalmology and optometry, "OS" is specifically designated for the left eye, whereas "OD" refers to the right eye (oculus dexter) and "OU" signifies both eyes (oculus uterque). Understanding these abbreviations is crucial for accurately interpreting prescriptions and instructions for eye care. The option "LA," which might suggest left eye, is not a recognized abbreviation in this context. Thus, "OS" is the correct term to use when referring specifically to the left eye.
