IO Tech officially launches at SILMO Paris 2026

SILMO Paris runs from September 25 to 28, 2026, at Paris Nord Villepinte, and IO Tech is using the show's visibility to officially launch. No physical booth this year — the shift IO Tech represents comes across just as well remotely, and a video demo is enough to show exactly what the technology changes at the counter.

What IO Tech changes

IO Tech measures pupillary distance and centering height for progressive and aspheric lenses directly from the store's smartphone, with no pupilometer or ruler needed. An artificial intelligence cross-checks three measurement protocols — distance, near, and screen vision — to make the result more reliable, including for wearers who spend a lot of time in front of a screen. The technology was tested and validated on thousands of real cases before this announcement.

Nothing else to buy

• No extra accessory needed: the app runs in the browser, on both iPhone and Android.
• Installs as a PWA (progressive web app) directly on the home screen, with no app store needed.
• No data sent to an external server: the measurement happens entirely in the phone's browser.

Two ways to get equipped

IO Tech offers a €4.90/month subscription (€58.80/year, 3-year minimum commitment), or a 3-year license as a single €245 payment for opticians who'd rather pay by bank transfer or invoice than by recurring card.
