Smart contact lenses: where does the technology stand?
Long touted as the next revolution in optics, smart contact lenses have fueled the collective imagination for over a decade. Augmented reality displays, blood glucose monitoring, intraocular pressure measurement, and targeted drug delivery: the promises were numerous.
By 2026, however, the situation is more nuanced. Technological progress is very real, but mass-market commercialization remains a long way off…
So, what are the main challenges facing the sector today? We'll explore them on the GEIE Eyes-Road blog!
Smart contact lenses move from dream to clinical research
A prime example of recent technological repositioning in the sector is the remarkable evolution of the company Mojo Vision.
After developing a functional prototype of an augmented reality lens , Mojo Vision eventually abandoned this project to focus its business on MicroLED micro-displays for other applications.
Meanwhile, Verily's (formerly Google Life Sciences) connected lens program dedicated to glucose monitoring had already been discontinued, as researchers were unable to establish a sufficiently reliable correlation between glucose present in tears and that in blood.
This development illustrates a reality: smart lenses are no longer just a futuristic concept, but they have not yet reached the expected industrial maturity…
Health is becoming the main driver of innovation
While consumer applications are progressing slowly, medical uses appear today to be the most promising.
Research is now focused on lenses capable of continuously measuring certain biomarkers present in tears: intraocular pressure, lactate, cortisol, electrolytes, and inflammatory markers. The goal is to offer non-invasive monitoring of certain chronic diseases, complementing traditional examinations.
Glaucoma , in particular, is one of the most advanced areas . Electronic devices already make it possible to record changes in intraocular pressure over 24 hours, providing ophthalmologists with data impossible to obtain during a single consultation.
Researchers are also exploring lenses capable of gradually delivering medication directly to the surface of the eye. This approach could improve the effectiveness of treatments while reducing the drawbacks associated with conventional eye drops, a significant portion of which is often washed away before taking effect.
Several scientific reviews published in 2025 highlight that smart materials, nanosensors and new biomaterials are significantly accelerating this research, although large-scale clinical validations are still needed before any mass dissemination.
Smart lenses and augmented reality: an ambition that remains.
The other major area of focus for smart contact lenses remains augmented reality.
The idea is to project information directly into the field of vision without using smart glasses .
Navigation, real-time translation, medical or industrial assistance: the potential uses are numerous.
However, the technical constraints remain considerable. A smart lens must integrate a microscopic screen, a power supply, communication antennas and various sensors, while remaining transparent, comfortable and perfectly safe for the eye.
New companies are nevertheless continuing their work, notably XPANCEO , which is developing prototypes combining augmented reality, biomedical sensors and new energy supply solutions.
However, most specialists believe that the first commercial applications will initially concern medical or professional uses before any possible democratization among the general public.
Promising prospects… but still cautious
Smart contact lenses remain one of the most fascinating areas of optical innovation. Yet, contrary to predictions made a few years ago, their development is progressing more gradually than dramatically. The main challenges still concern power supply, component miniaturization, data transmission, biocompatibility, and regulatory requirements.
Recently, the sector seems to have found a more realistic direction: rather than immediately seeking to replace smartphones or smart glasses, researchers are prioritizing applications where medical value is clearly demonstrated. Glaucoma monitoring, targeted treatment delivery, surveillance of certain biomarkers, and support for chronic diseases are currently the most promising avenues.
For optical professionals, this research primarily reflects a profound evolution in the role of contact lenses. Tomorrow, they could become not only vision correction devices, but also true platforms for diagnosis, prevention, and personalized healthcare.
The anticipated revolution may not be abandoned: it is simply taking longer than expected to meet the safety, reliability, and performance requirements that characterize next-generation medical devices…
