Step-by-step explanation:
In the context of eye care, O.S., O.D., and O.U. represent different aspects of vision correction. These abbreviations are used to identify the eye(s) being referred to in a prescription for eyeglasses or contact lenses.
The abbreviation O.S. stands for oculus sinister, which means left eye in Latin. The abbreviation O.D. stands for oculus dexter, which means right eye in Latin. The abbreviation O.U. stands for oculus uterque, which means both eyes in Latin.
By identifying which eye or eyes need vision correction, optometrists and ophthalmologists can prescribe the appropriate corrective lenses for each eye.
