Get your glasses just right with Opthy, powered by #1 global eyewear experts EssilorLuxottica.

Buying glasses online can be overwhelming. With just a few clicks, Opthy measures your Pupillary Distance – or PD for short – allowing you to find the most comfortable and personalized fit.

Key features
Opthy is an advanced contactless tool that captures multiple measurements within seconds. This is the basis for calculating your PD value.

What is Pupillary Distance?
It’s the distance between the center of your pupils, measured in millimeters. An average PD measurement is about 63mm.

Why it matters?
Knowing your Pupillary Distance is essential when buying glasses. It indicates which part of the lens you look through, ensuring optimal comfort and clarity.

How it works?
All you need is your iPhone – it’s that simple. The app will walk you through your scan and, once done, will tell you the all-important number.
