How to measure your PD
The 'PD' is the distance in mm from the centre of one pupil to the other. Also known as the 'Pupil Distance'.
This measurement is especially important for individuals who have high powered lenses in their glasses.
The 'PD' measurement is sometimes written on your prescription, which is given to you by your Optometrist at your eye exam. It can be given as one number together e.g. 61mm, or two numbers for each eye e.g. 30mm & 31mm (called Mono PD's).
The measurement of your pupils can also be done easily at home, either on your own or with a friend.
