The abbreviation OS stands for which of the following?

Explanation:
In eye care notation, OS stands for oculus sinister, which means the left eye. This system uses OD for the right eye and OU for both eyes, so OS specifically identifies the left eye. The other possibilities describe the right eye, both eyes, or an unrelated term like eye movement, so they don’t fit with this abbreviation.
