We're going to use super savvy, cutting-edge tech to measure the distance between your pupils. To make sure it works perfectly, make sure you're in a well lit room (no bright backlights) and got that good wifi. Grab a standard size, light colored card with a magnetic strip. Turn on the audio, and let's go!

If you are on desktop, make sure you're using Safari, Chrome or Firefox. For mobile, jump on Safari if you have an iPhone, and Chrome if you are on an Android.

A standard size card gives us something to scale in order to measure the distance between your pupils. There's never a need to use a credit card (please don't, really). Drivers license, library card, club card — they all work great.

A couple FYIs: We only access your camera for the duration of the scan, and we are big on security. Our tech also automatically blurs any details on your card so they cannot be recognized. Finally, your image will never be linked to personal identifiable information. For more, check out our Privacy Policy.

There's a few things that help our tech work it's magic. First, make sure your audio is on to hear some clues on what you might be missing. You'll want to look straight into the camera and have your eyes clearly visible. (Sorry bangs, but we're going to have to push you aside.) Place your card with the magnetic strip on the bottom, right above your eyebrows. Hold the card at the top corner so the magnetic strip is clearly visible. Make sure you're in a well lit environment and that camera is squeaky clean (no finger smudges please). If you're still having issues, contact us! We can help.
