Before starting the I-SEE project, Laclarée had already developed a first generation of autofocusing glasses that reach a TRL between 6 and 7. It has been validated through internal testing in various current life situations, in a clinical explorative study performed in 2021 with the CHU of St Etienne (Team of Pr GAIN) on 40 patients. These tests were completed by interviews of hundreds of patients, about 400 have tried our prototype. Value proposition was validated during these tests. Laclarée has also validated its market and its Go-To-Market strategy, following a convergence of directions coming from wearers, optical chains and independent opticians, insutry majors.
February 2025: Laclarée has frozen the definition of the first product. The high-level specifications are set and technical specifications of the sub-systems are being finalized.
The Gamma project by Laclarée introduces the first commercial adaptive eyeglasses, designed to automatically correct presbyopia and static vision defects (myopia, hyperopia, astigmatism) using microfluidic lenses controlled by embedded electronics. The system integrates ToF (Time-of-Flight) sensors for real-time distance measurement, enabling seamless autofocus with a response time under 1 second. The lenses feature a 20 mm variable zone for close-up vision, ensuring a wider field of view compared to progressive lenses.
April 2025: The deliverable D2 (Frame design) completed the first design of the Gamma line of eyewear including our technology. The goal is to combine reliability, ergonomics, and aesthetics for a high-end product. The design features a hinge-free architecture to enhance robustness and reduce bulk, along with a wired connection between the temples to simplify electronic development and lower energy consumption. Electronic and fluidic components (actuators, PCB, batteries, ToF sensors) are integrated optimally to minimize temple thickness and ensure comfort. Batteries, positioned at the temple ends, act as counterweights to balance weight distribution. The ToF sensors and cover glasses are highlighted as a design signature while adhering to strict tolerances for reliable distance measurement. Comfort is achieved through tailored geometry (saddle nose bridge, silicone tips) and stability, thanks to a pre-curved shape that fits the head. The design also meets safety constraints (allergy, flammability, mechanical resistance) and facilitates maintenance and recycling. The style targets the identified personas, with a unisex approach and customizable finishes.
June 2025: We established the technical requirements for the adaptive Gamma eyeglasses' subsystems: microfluidic actuator, smartphone app, electronics, optical liquids, deformable membrane and thermal buffer module. Each component is designed for automatic vision correction, durability, and ergonomic integration.
