Pupillary Distance

We need your Pupillary Distance (PD) to ensure that your glasses are customized to fit you perfectly. PD is the distance between the centers of each eye. Once we get your PD we can finish your glasses!

Kid PD Range: 35-65 mm.

Adult PD Range: 50-80 mm.

If your PD has 2 numbers, it is typically written 22/20 on your prescription. The first number is the right eye (OD), and the second is the left eye (OS).

1) ONLINE PD TOOL: Virtually measure your PD using our online tool! Click the "Measure My PD" button and follow the on screen instructions. Then enter your PD number in the form.

2) EMAIL A PHOTO: If your little squirmy wormy can't sit still long enough for the online tool (we totally get it!), you can just take a picture at home and we'll measure the PD for you. Follow these directions here.

Can't get the PD Tool to work for your little one?

Sometimes it can be hard with little ones, we totally get it! Take a picture following these directions and we'll measure the PD for you:

1. Remove your glasses.
2. Hold a credit card (or similar) centered below your nose.
3. Look directly ahead and take a picture.
4. Email your photo to helpme@roshambo.com.
