Method for the realization of the photos of the measurements:
Photos to be sent to: firstname.lastname@example.org ( you can do a we-transfer if the files are too big )
Here is the method for the measurement:
1: You hold a double decimeter on your forehead horizontally (without the mask), just above your eyes.
2: You ask a friend to stand three metres in front of you
3: This same friend takes a picture of you by zooming in on the face
4: You send us this photo
5: Then you do the same but with the mask on your nose and with the double decimeter upright.
Mistakes to avoid:
- Do not take a picture of yourself alone with the computer webcam, you should look far away with a natural head carriage
- The graduations in millimetres must be visible on the photo
- You must take the photo with the chosen mask model, the measurement is specific to the chosen mask
- The pupillary distance is not provided on the prescription, you must in any case take both photos
