We totally get that reading your prescription can be tricky if you're not an optician! That's why we've created the following list to make the whole thing simpler.
OD = Right eye
OS = Left eye
SPH = SPHERE power. It indicates the amount of lens power prescribed for nearsightedness (-) or farsightedness (+).
CYL = CYLINDER power - the degree of astigmatism
AXIS = The direction of astigmatism, measured in degrees (1-180)
ADD = Provides the additional magnifying power of reading, progressive and computer lenses. It’s always a positive value
PD = Pupillary distance. It’s the distance between the center of one pupil to the center of the other pupil, measured in millimeters. Learn how to measure this value by yourself HERE
