If you already have a PD, look for an abbreviated “PD” column on the lower part of your prescription slip.
If there are two pupillary values in your prescriptions, you might have to measure the distance between each
pupil to the center of the nose bridge individually.
In case your PD measurement is not coming out right, you can also take help from a friend or visit your
optometrist / optician to get your exact Pupillary distance.
