New breakthrough ‘Opthy’ app measures pupillary distance
3 min read

Available as a pilot to consumers on LensCrafters.com in the US, the innovative app offers a convenient solution to measure pupillary distance from home, helping consumers buy glasses online that best meet their needs.

Useful when making online optical purchases, Opthy allows consumers to directly measure their pupillary distance (PD) – the space between the center of the pupils – with a few simple clicks using an iPhone.

Precise PD data adds value because it determines the optical center of the lenses, helping ensure glasses are correctly aligned and focused according to the consumer’s specific needs for optimal comfort and clarity. In contrast, an inaccurate PD measurement can have negative effects on eyesight, causing eye strain, fatigue, headaches or distorted vision.

Launched for consumers in the US on LensCrafters.com, Opthy enhances the digital consumer journey, powered by advanced technology that matches the high-quality service EssilorLuxottica (LensCrafters’ parent company), as a global leader, aims to offer consumers.

With e-commerce booming now more than ever, LensCrafters remains focused on enhancing the consumer experience with engaging and cutting-edge tools.
