IXI, a Finnish startup, has made waves with what it claims to be the “world’s first autofocus eyewear.” Their latest innovation, IXI Adaptive Eyewear, reimagines conventional vision correction with smart glasses that automatically adjust focus in real time, much like a human eye. The result? A single pair of glasses that supports both near and far vision, eliminating the need for bifocals or progressive lenses.
IXI was founded in 2021 in Espoo, Finland, by a team of optical engineers and tech entrepreneurs led by Niko Eiden (CEO) and Ville Miettinen (Chief Algorithm Officer). Before launching IXI, the duo co-founded Varjo, a mixed reality hardware company known for its precision optics and eye-tracking technology.
By June 2021, IXI had already secured $4.4 million in funding to activate its research and development and IP strategy. This funding round drew support from a mix of investors including the Amazon Alexa fund, Maki.vc, First Fellow, firstminute capital, John Lindfors, Illusian and Bragiel Brothers. In April 2025, IXI announced it had raised $36.5 million in a funding round led by Plural. Other investors included Tesi, byFounders, Tiny Supercomputer, Heartcore, Eurazeo, FOV Ventures and existing backers like the Amazon Alexa Fund.
Originally named Pixieray, the company rebranded to IXI in March 2025. Building on their background in immersive tech, IXI is applying that same level of precision to everyday vision correction through the IXI Adaptive Eyewear.
Expanding eyewear industry
As of 2024, the global eyewear market is valued at $200 billion and is expected to increase to approximately 68% by 2030. Major players in the industry include those focusing on traditional eyewears, contact lenses, and pharmaceuticals such as Bausch and Lomb, Charmant Group, and CooperVision.
At the same time, companies like Carl Zeiss AG, Warby Parker, and EssilorLuxottica are active in smart glasses research and development. Carl Zeiss has developed SmartLife lenses which use adaptive 3D object-space modeling and age-specific pupil optimization to passively enhance visual comfort and peripheral clarity. Warby Parker has collaborated with Google in developing AI glasses with voice and health tools. EssilorLuxottica has extended its partnership with Meta for their Ray-Ban Meta glasses which offers AI, audio, and camera.

Tech behind the lenses
IXI Adaptive Eyewear combines eye-tracking sensors, compact actuators, and liquid crystal lenses to deliver real-time autofocus. When the user shifts focus, embedded sensors detect changes in eye convergence, and a microcontroller in the nose bridge adjusts the liquid crystal lenses accordingly, typically completing the adjustment in under 0.2 seconds.
This hands-free, intelligent adaptation tackles presbyopia head-on and removes the need for switching between different glasses or using multifocal lenses.
The next section explores IXI’s patent portfolio and how it strengthens its position in the competitive smart vision space.
IXI: Patenting Activity
Our analysis shows that 2023 marked IXI’s most active year in global patent fillings with 45 fillings strengthening its prototyping efforts for autofocus eyewear. Since 2024, filings have slowed, attributing to its focus in product development. As of April 2025, IXI has already raised $36.5 million in Series A funding. However, the company has yet to announce the launch date for its product.
IXI: Top Law Firms
As a startup, IXI has relied on a small group of firms for their patent filings. Our data indicates that Moosedog Oy was the leading representative for IXI, handling 31 patent filings, including the company’s first patent filing in 2021. For U.S. filings, IXI has worked with Ziegler IP Law Group, LLC. Other notable legal representatives are Koki Kawamorita and He Qiuyuan, who handled regional patent filings in Japan and Taiwan, respectively.
IXI: Top Technology Areas
In developing their smart eyewear, IXI’s patent portfolio is primarily concentrated in G02C and G02B, which covers optical elements and systems. Other notable classifications are A61B, and A61F, which reflects the purpose of the IXI Adaptive Eyewear in addressing both near and far vision conditions. In addition, classifications such as electrical digital data processing (G06F), light measurements (G01J), wireless communication networks (H04W) and circuit arrangements (H02J) highlight IXI’s IP strategy to protect the smart hardware behind its real-time autofocus capability.
Blending form and function
Design plays a central role in IXI. According to an article by IXI’s Chief Design Officer, Timo Yliluoma, great design is not just about aesthetics but also about purpose. While their smart eyewear is developed with advanced technology, equal attention is given to how it looks, since eyeglasses are, after all, a fashion statement, whether the wearer likes it or not. The next section looks at how IXI’s patents show a blend of smart engineering and thoughtful design.
Zone-controlled lenses with dynamic optical power adjustment
U.S. Patent No. 12,222,504, titled “Optical elements with spatially-variable optical power”, describes an improved optical apparatus that dynamically adjusts focus across multiple zones of a lens. Each eye is fitted with an active optical element encased between two transparent substrates. A processor controls specific regions of the lens, including a central zone and surrounding sectors, to alter optical power as needed. This allows for precise, low-power focus adjustment based on where the user is looking.
The system improves upon traditional optics by enabling localized control instead of uniform lens changes. A corresponding manufacturing method is also described, emphasizing efficient integration of the active material, control elements, and processor. The innovation aims to enhance visual performance while reducing power consumption and mechanical complexity.
This patent was filed on February 11, 2022 and was granted on February 11, 2025, with Klaus Melakari, Niko Eiden, and Rebecca Qing Melakari as the inventors.
Temperature-calibrated tracking for real-time gaze accuracy
U.S. Patent No. 12,104,952, titled “Calibration arrangement, method for calibrating light intensity reading and a system for determining gaze direction”, presents a system for calibrating light intensity readings in gaze-tracking systems, particularly those using light emitting diodes (LEDs) in head-mounted displays (HMDs) or autofocus eyewear.
Prolonged use of such devices can raise the temperature of LEDs and photodiodes, causing fluctuations in light output, wavelength shifts, and latency which ultimately degrades gaze tracking accuracy.
The proposed calibration arrangement compensates for these temperature-induced variances to ensure reliable eye-tracking performance. By stabilizing light intensity readings, the system can precisely determine the user’s gaze direction, which is critical for applications such as augmented reality, interactive gaming, and dynamic lens focusing in smart glasses.
The patent was filed on October 3, 2023 and was granted on October 1, 2024. It listed Klaus Melakari, Juha Timonen, and Ari Pitkänen as inventors.
Invisible lens adjustment during eye movement
Alt text: IXI’s adaptive lenses
U.S. Pat. App. No. 2025/0004269, titled “Optical adjustment in adaptive lenses during saccades”, introduces an optical apparatus and method for adjusting adaptive lenses in a way that remains imperceptible to the user. The key innovation lies in timing lens adjustments to occur during saccades, which are the rapid, involuntary eye movements made between fixation points.
By synchronizing changes in optical parameters with these brief moments when visual input is naturally suppressed, the apparatus delivers a smoother, more comfortable viewing experience without noticeable shifts in focus.
This approach addresses limitations of previous adaptive lens systems that could distract users or delay visual clarity. The system enhances real-time adaptability while maintaining visual continuity, particularly for applications like smart glasses or augmented vision.
The patent application was filed on June 28, 2023, and was published on January 2, 2025. The application lists Ville Miettinen, Mikko Kataja, Klaus Melakari as inventors.
