Instructions for DNP Measurement

Naso-Pupillary Distance is essential for us to make your glasses to measure for you!
The process to find out your NPD is very simple and quick.
You will need:

- A card with a magnetic stripe
- A well-lit environment to take your photo 

Correct way to get your DNP:

  • Place the credit card in front of your mouth below your nose and look straight ahead like a 3x4 photo.
  • The card should be horizontal, hold it so that its data is not exposed. Position the credit card in front of your mouth below your nose and look straight ahead.

Incorrect way to get your DNP:

  • Don't keep the card away from your face
  • Don't look to the sides, you must look straight at a distant point.
  • Do not position the cell phone upside down, it has to be straight
