Research & design

Designed by the most innovative R&D process

We changed our approach when designing X series. We put the wearer at the centre of our research. We conducted a worldwide survey of presbyopes, including focus groups, selfie videos to gather a full understanding of their visual challenges.

A new innovation process



In order to develop a revolutionary Varilux lens we transformed our research process to completely focus on wearers. We conducted a far-reaching societal study with presbyopes across the world, which included online testimonials and selfie feedback.

Experimental behaviour lab

To truly understand presbyopes behavioural needs we developed Movis, an experimental behaviour lab. Movis allowed us to capture visual and postural behaviours in real time and 3D by attaching sensors to test subjects.


To qualify our hypotheses we tested our findings in  our simulator environment.

House lab

Patient feedback is key. Varilux X series was put to the test within a House Lab. Lens wearers were asked to take part in everyday tasks such as walking down stairs, multi-tasking and were asked to feedback their experiences.
