A closer look at how the lenses, frame, and precision components come together in VIVIFoCAL S1.
Every pair is assembled, calibrated, and inspected
on our own lines — before it ships to you.
From adaptive focus to blue-light filtering, explore the technology behind S1 through real-world tests and optical measurements.
TEST 01 · OPTICAL POWER
As S1’s lens elements shift, their optical power changes. Lensmeter readings capture these changes within the 0–3.5D range, demonstrating how S1 adjusts focus from near to far.
TEST 02 · BLUE LIGHT FILTERING
Designed for everyday screen use, S1 helps filter blue light. Under blue-light exposure, the test card changes color, while the area covered by the S1 lens shows no visible color change.
Four systems working as one — so your glasses do the adjusting, not you.
Real parts, real lines, real units — already in production
01-SENSING
A ToF (time-of-flight) sensor built into the bridge transmits light-wave signals toward whatever you're looking at, then receives the reflected signals back — measuring the distance to your point of focus in real time, from 8 inches to infinity.
01 SENSING
The ToF sensor measures your viewing distance in real time, giving the system the data it needs to focus accurately.
02-COMPUTING
Based on distance sensing, consumer behavior, and user intention algorithms, the required lens displacement is calculated to achieve the desired power.
02 COMPUTING
The MCU processes the distance data and determines the precise lens adjustment needed for clear vision.
03-ACTUATION
The MCU calculates the lens movement needed to adjust focus and directs the motor to make it happen. VIVIFoCAL’s proprietary transmission mechanism then turns that motion into controlled, precise lens adjustments.
03 ACTUATION
The motor shifts the Alvarez lenses into position, bringing your view into clear focus in under 0.1 seconds.

04-FOCUSING
The Alvarez lens system uses two moving lens elements to adjust optical power, bringing your view into focus as you look from near to far.
