Next generation pupillary distance (PD) measurements


What is MIRA?

Using only a phone or tablet and a mirror, our app accurately calculates your Pupillary Distance (PD), from the comfort of your own home. In three easy steps, you can download our app, follow the tutorial and get your accurate PD measurements sent directly to your SelectSpecs order.

3 Easy Steps


Step 1

If you have selected to use our PD measurement app when placing your order, we will send you an email after your order is processed. Simply click the link provided in this email to download and open the Mira app.


Step 2

Once the app is open, follow the tutorial to take your PD measurements.


Step 3

Once finished, the app will send your measurements to the cloud where they will be verified by an optician and then sent to the SelectSpecs team who will apply them to your order.

Why use MIRA?

Mira Measure is different from other PD measuring applications, with our technology there is absolutely no need for a scaling device. Our sophisticated algorithms calculate your pupillary distance measurements by taking a 3D scan of your face and eyes and deliver to SelectSpecs, all key details needed to make your perfect glasses.

Why do I need to stand in front of a mirror?

A mirror helps us create the 3D image from which to make calculations. In this way we remove the need for scaling devices and rely on algorithms based on your exact facial measurements.

What size should the mirror be?

The mirror should be roughly half-length. You don’t need to stand around with a tape measure checking the size, but we do recommend that you are able to see the top half of your body in it.

Can I use this app on any device?

This application is currently supported by Apple iOS (iPhone & iPad) and Android devices.
