This is the distance between the center of each pupil. We use this measurement to indicate where the optical center of each lens is. Without an accurate PD measurement, correcting vision can be difficult, as lenses need to be aligned over the center of your pupil for proper clarity. When taking your eye exam, this measurement is usually taken, but is also often times withheld from your prescription by provider.
To provide us with this measurement, you may do any one of the following:
1. Check with your doctor.
This measurement may or may not have been taken during your examination. It can’t hurt to check to see if they are able to provide the measurement for you!
2. Use measurements from existing lenses.
If the lenses in the frames you are sending to us already have your pupil distance, we are able to use that. Please note that this is not always an accurate method, and would depend on the condition of those lenses. If the pupil distance requires adjusting after we have gone this route, there would be a fee associated with that.
3. Submit a photo of yourself holding a credit card (sample photo below).
We use a credit card as the base measurement, so the card in the photo must be the standard size. The card should be held by two fingers — placed directly beneath your nose, and pressed against your lips. Look directly forward at the camera lens, and please do not wear any glasses for this photo.
