OD stands for “oculus dexter,” or right eye.
OS stands for “oculus sinister,” or left eye.
if there is PL or DS in your prescription, it means the value should be 0.
The term PL (Plano) means there is no spherical correction in this eye.
DS stands for “diopter sphere”, which means there is no astigmatism correction for this eye.
