Pupil Distance
One last step before checkout
Pupil distance (PD) is the distance in millimeters between the centers of your pupils. It's used to align the optical center of your lenses with your eyes. Most adults have a PD between 54–74 mm. You can find it on your prescription or ask your eye doctor.
Measure Your PD
We recommend using the EyeMeasure app for accurate results
Use your iPhone's TrueDepth camera to measure your pupil distance in seconds. It's the same technology used by opticians.
