Measuring Pupillary Distance

Pupillary Distance (PD) is the horizontal distance between your child’s pupils. Measured in millimeters, this distance is used to ensure that your child’s lenses are positioned correctly in front of your child’s eyes.

Measuring PD can be challenging. Ask your Ophthalmologist to measure it as part of your child’s eye examination.
Otherwise, you can obtain it using the “Pupil Meter” App, which you can download to your android or iPhone. We have tried it with children and it works great; just follow the simple instructions. Call us at 1-855-OPTIWOW (855-678-4969) or email us if you have any trouble and we will help you.
