VIVIFoCAL says its S1 glasses automatically adjust focus by sensing how far away you are looking, calculating a lens change, and moving adjustable lenses. They are marketed for people with presbyopia, but the advertised range and speed are company claims—not independently verified results. The system adjusts focus; it does not determine a medically correct prescription.
How the VIVIFoCAL S1 says it focuses
VIVIFoCAL describes a three-part process: a time-of-flight (ToF) sensor measures viewing distance, a microcontroller (MCU) calculates the needed adjustment, and a motor shifts the glasses’ Alvarez lenses. The company explains: “The ToF sensor measures your viewing distance in real time, giving the system the data it needs to focus accurately.” VIVIFoCAL’s product description
In practical terms, “focus themselves” means the eyewear is designed to change its optical focus as the wearer looks between near and far objects. It does not mean the glasses diagnose an eye condition or choose a prescription. VIVIFoCAL describes prescription support and app-based fine-tuning of near correction, so prescription needs remain part of the setup.
What the advertised specifications do—and do not—establish
| Manufacturer specification | What VIVIFoCAL advertises | Evidence qualification |
|---|---|---|
| Focus range | 8 inches to infinity | Company claim on its undated product page; no independent validation identified. VIVIFoCAL |
| Response time | Under 0.1 seconds | Company claim on its undated product page; not an independently measured result. VIVIFoCAL |
| Adjustment precision | 0.01D | Company claim on its undated homepage; testing conditions are not established in the sources reviewed. VIVIFoCAL homepage |
| Designed daily wear | 8+ hours | Company design claim on its undated homepage, not a reported independent battery or wear test. VIVIFoCAL homepage |
These figures describe what the maker advertises, not demonstrated performance across users or conditions. A company recap dated July 31, 2026, says VIVIFoCAL demonstrated adaptive focus at WonderFest 2026 using a 1/35-scale miniature and was preparing for Kickstarter. That account documents the company’s demonstration, not a controlled test. VIVIFoCAL’s recap An October 1, 2026 Yanko Design article also describes the sensor, microcontroller, actuator, and mechanically shifting lenses; it does not provide independent performance validation.

Who the S1 is intended for, and where the maker says to use it
The reservation page describes the intended audience as people with presbyopia, including people who also have nearsightedness, farsightedness, or astigmatism. VIVIFoCAL positions the glasses for everyday office and workspace tasks such as reading and computer work. This is the manufacturer’s intended-use guidance, not medical advice. VIVIFoCAL reservation page
The same page cautions against driving, operating motor vehicles or heavy machinery, and strenuous work in dynamic environments. It also says that a 3–7 day adjustment period may be normal and that focus transitions—or a gentle sound as the lenses move—may occur. VIVIFoCAL reservation page

The intended purpose—adjusting focus between near and far viewing—overlaps with tasks people may use reading glasses or progressive lenses for. But the available information does not establish that the S1 can replace either option for a particular wearer, or that it performs better than conventional lenses. The sources reviewed provide no named independent study, published clinical statistic, or comparative test result for the S1.
