We'll need your pupillary distance (PD) to properly re-lens your frames. It could already be written on your prescription.
If not there's a few EASY ways you can measure, or even WE can help you measure it.
1. Use a ruler and measure the distance between your pupils. For distance glasses, make sure you're looking straight ahead and afar. For readers, focus on something within 14 inches, or a little more if it's for computer use.
2. OR Send us a selfie with the ruler on your forehead
3. OR send us a selfie with a credit card on your forehead, and we'll use that proportion to calculate your PD. Make sure everything's lined up and symmetrical, including your camera angle. And make sure you block out the numbers on the card.
