A Finnish tech company is reinventing eyewear, promising a future where glasses automatically adjust to your vision needs — near or far — in real time. No more switching between reading and distance glasses. No more awkward bifocals.
The innovation? Autofocus lenses using liquid crystal technology, developed by IXI, a startup based in Finland.
“People don’t want to look like cyborgs,” says CEO and co-founder Niko Eiden, holding up what looks like a regular pair of glasses during a Zoom interview.
But these aren’t ordinary glasses.
🔬 How They Work
Inside the lenses are liquid crystals that adjust when triggered by an electric field. This lets the lenses instantly change focus based on where you're looking. An eye-tracking sensor built into the frame detects what kind of vision correction you need — whether you're reading or looking across the room.
“It’s fully tunable,” explains Eiden. “You can go from near to far vision seamlessly.”Unlike traditional bifocals or varifocals, where you must shift your gaze to specific parts of the lens, these autofocus glasses do the adjusting for you — dynamically, on the fly.
⚙️ The Technology Is Evolving
Admittedly, IXI’s first prototypes weren’t great — hazy lenses, blurry edges. But recent versions are showing promise. In trials, users were asked to switch quickly between reading a page and viewing distant objects. The glasses responded smoothly.
“Participants noticed the transition felt natural,” says Eiden.
Still, there are design challenges. Because of the delicate electronics inside, the frames can’t be highly adjustable, says Emilia Helin, product director at IXI. So the company designed a small range of frames that should fit most face shapes. The built-in battery lasts up to two days and can be recharged overnight.
Eiden wouldn't confirm pricing but smiled when asked if it would be around £1,000 ($1,250 USD) — hinting that the high-tech specs might come with a premium price tag.
👁 Who Needs Autofocus Glasses?
Autofocus specs could be a game-changer for:
- People with presbyopia (age-related difficulty focusing on near objects)
- Those tired of switching between multiple glasses
- Anyone who struggles with bifocals or varifocals
But not everyone is fully convinced yet.
“We don’t know if they perform well enough for tasks like driving,” says Paramdeep Bilkhu, clinical adviser at the UK’s College of Optometrists.
Optometry researcher Chi-Ho To from Hong Kong Polytechnic University agrees. He supports the idea of dynamic lenses for general use — but raises concerns about accuracy and timing in high-risk situations, like surgery.
🧪 Are Autofocus Lenses the Future?
The concept of self-adjusting glasses isn’t entirely new. UK-based company Adlens once sold dial-controlled fluid-filled lenses for $1,250 in the U.S. They worked but didn’t catch on with opticians — stifling adoption.
Now, companies like IXI, Adlens, and others are racing to create sleeker, smarter glasses with fully automatic lens adjustment, without the need for dials or manual input.
Physicist Joshua Silver, who founded Adlens, developed a similar concept in 1985. His low-cost adjustable lenses have helped over 100,000 people in 20 countries. He’s now fundraising for a new project called Vision to expand the reach of this technology.
But he remains skeptical about ultra-expensive smart specs:
“Wouldn’t most people just buy $10 reading glasses?”
👓 Smart Glasses That Do More Than Correct Vision
The tech isn't just about clarity. Some smart glasses aim to slow or even reverse eye conditions like myopia (nearsightedness), especially in children.
- Prof. To has developed lenses with honeycomb rings that slightly blur peripheral vision, slowing eyeball growth and cutting myopia progression by 60%. These glasses are now used in over 30 countries.
- UK-based SightGlass offers a different approach, gently lowering contrast to slow myopia in children.
To's ultimate dream? Glasses that not only stop myopia — but reverse it.
“There’s growing evidence that you can do it,” he teases.
🔮 The Bottom Line
Autofocus smart glasses are getting closer to real-world use. While the tech still has hurdles to overcome — from design limitations to high costs — it’s a glimpse into the future of vision correction.
From liquid crystals to myopia-slowing lenses, your next pair of glasses could be smarter than ever before.
