How to take a selfie!
Posted by Cortel Designs on 22nd Mar 2026
To proceed, we require your Pupillary Distance (PD) and Working Distance (WD). We can determine your PD from a selfie by following these steps:
1. Positioning: Place the back of a credit card, gift card, or ruler against your face, directly underneath your nose. The width of the card allows us to calibrate the measurement accurately.
2. Taking the Photo: Extend your arm so the phone camera is approximately 17 inches away. Look directly at the camera while taking the picture.
Additionally, please provide your Working Distance. You can find this by measuring the distance from the outside corner of your eye to the object you are viewing while in a comfortable position. The average WD is typically 17 inches.
"Please inform us if you use corrective lenses or readers—this is essential for adjusting your loupe’s working distance."
