Hear It from Our Early Users
See how S1 becomes part of daily routines through moments shared by people who wear it.
Jason Eaton
Jason puts S1 to the test across different viewing distances—from detailed model work to his computer screen and surroundings. He shares how S1 compares with his regular glasses in clarity, comfort, and everyday use.
John Sabean
In his home workshop, John takes on detailed DIY projects that demand close attention, including precision soldering. S1 joins him at the workbench, where small components and intricate tasks call for a closer look.
Oggie Gonzalez
As both a model builder and an optometrist, Interstellar Modeler tests S1 during detailed hands-on projects and compares its focusing experience with traditional glasses, sharing his perspective on its performance and practical limitations.
Frank
From multiple computer screens to documents on paper, Frank’s workday involves frequent shifts between digital and printed material. See how S1 adapts focus as he moves through his everyday workflow.
I can walk past the equipment, read tiny serial numbers without stopping and see the information I need. This is a productivity gain and a huge plus for me.
Fr*****W.
System Engineer
It's kind of fun, looking around and seeing everything change. It's very clear. Very, very good, and it changes so quickly.
Ju*****L.
UX Designer
With your glasses, I can walk around perfectly and the focus adjusts... As I move between my artwork and reference photo, the focus adjusts quickly and both are clear when I need them.
Pa*****P.
Painter/Designer
It’s surprisingly lightweight, and I really like how quickly the lenses adjust between different viewing distances.

" I would look down at a part number on a piece of paper, look backup at the screen to type it in, and the glasses just kept right up with me"
TECHNO TESTED
"I’m doing ordinary activieties, and that’s exactly the point. The technology needs to be useful during noarmal life, and not just during a carefully controlled demonstration."
Eyewear Should Adapt to You.
The Technology Behind S1
Innovation, design, and precision engineering come together
How VIVIFoCAL Works
01 SENSING
You look. It senses the distance.
The ToF sensor measures the distance to the object that you're looking at in real time and sends the distance data to the system.
02 COMPUTING
It calculates the lens adjustment.
The MCU processes the distance data and determines the precise lens position for that viewing distance.
03 ACTUATION
The lenses adjust. Instantly.
The motor shifts the lenses into position, completing the adjustment in under 0.1 seconds.
Focus Instantly. Smooth Transitions.
Multi-sensor perception enable adjustments in under 0.1 seconds. Each transition happens quickly and smoothly, creating a natural experience with minimal interruption.
From Near to Far. One Pair Keeps Up.
With an extended focus range from 8 inches to infinity, it supports daily activities from reading and screen use to hands-on tasks and farther viewing distances—reducing the need to switch between glasses and keeping your workflow uninterrupted.
Full-Lens Clarity. Clear Without the Search.
Unlike traditional progressive lens designs that rely on specific viewing zones, VIVIFoCAL S1 is designed for a wider usable viewing area, so you can move through everyday tasks more naturally without constantly adjusting your head position to find the right spot.
