Creal, a Swiss startup building augmented reality glasses, has announced a breakthrough in “light field” technology that can dramatically improve AR vision.
The Lausanne, Switzerland-based company unveiled its revolutionary AR display technology stack, which is set to be commercially available by early 2024, when it can be integrated into other products. Tomas Sluka, CEO of Creal, said in an interview with GamesBeat that the tech makes it more comfortable to wear AR glasses and will reduce eye strain, fatigue and nausea.
“Augmented reality should be the next communication interface. The logic is simple. Seeing the digital information in the same way we see reality is more natural,” Sluka said. “So the only thing which holds it back is that it’s not easy to do it. And the first thing is that it should be natural.”
The patent-protected solution enables original equipment manufacturers (OEMs) and original design manufacturers (ODMs) to develop augmented reality (AR) glasses that provide users with accurate depth perception.

“It took us five years to bring the initial idea to actually work in a device,” Sluka said. “So it’s not a science fiction anymore. Many people still consider this hologram image as science fiction that is not practical. But it is.”
Distinguishing itself from conventional flat displays on the market, Creal’s light field-based content offers what it calls a true-to-life visual experience with realistic depth, even when viewed through a single eye.
Sluka said, “Today, 3D is incomplete. If you try any 3D headset on the market, they present in 3D, but they actually present flat images. This is the big problem because it ignores the fact that even one eye senses depth by focus and other cues. So our eye is able to focus only on your hand, or the bird on the display. It means you can’t see them. If you try to focus on your hand, everything fat is blurred. And if you don’t see what the display shows, then the display basically doesn’t work.”
It’s possible to correct the depth by mirroring the way light behaves in the real world. Humans can naturally do this change of focus with their eyes.
