The Pupil Distance or otherwise known as Pupillary Distance (PD) is the distance between your two pupils, measured in millimeters (mm). This measurement is required for us to center the lenses correctly in the glasses/goggles so that you are looking through the center of the lenses. If you are ordering just the glasses/goggles frame only without prescription lenses, please enter "not applicable" in the pupil distance selection field when adding your glasses to your shopping cart.
Please note if you are ordering prescription lenses with your glasses/goggles and if we are not provided with your pupil distance (PD), we will use the following pupil distances by default, except for universal goggles insert and diving mask orders (Please state age of the end-user under special instructions when ordering):
- Adults Glasses/Goggles (Age 14+): 63 mm
- Kids Glasses/Goggles (10 to 13 year olds): 60 mm
- Kids Glasses/Goggles: (6 to 9 year olds): 56 mm
- Young Kids Glasses/Goggles: (2 to 5 year olds): 49 mm
If your pupil distance (PD) is not written on your prescription, and you cannot obtain this from your Optician (who should have it on file), then please use our online PD measuring tool here:
