Creal Clarity light field display technology renders 3D AR scenes with full depth information
Creal has made available its Clarity light field display technology to AR glasses manufacturers for integration. The groundbreaking display technology reproduces the full 3D depth information of an artificial reality scene, allowing the eyes to focus naturally on virtual objects both near and far.
Traditional AR glasses project light from micro displays into the eyes at a set focal distance. When users of AR glasses focus on the virtual image, real world objects near and far are out of focus. When they focus on the real world objects, the projected virtual image is out of focus.
Creal Clarity reproduces the light beams that emanate from virtual objects just like a real world scene, including all the differences in parallax that naturally occur when focusing on objects near or far. Clarity renders over 1,000 depth plane images of the field of view and uses pinhole-like optics to project the entire light field of images into the eyes.
Users focus on 3D objects in the AR scene naturally, without eye strain, nausea, or other health issues of traditional AR glasses that project images at a fixed distance. Creal Clarity reproduces virtual worlds with high spatial resolution that matches or betters current AR glasses, with over a 1,000:1 contrast ratio.
The projection technology not only maintains high lens clarity, but can also correct for near and far sightedness by rendering light fields as seen through simulated prescription glasses, eliminating the need for prescription AR lens inserts.

One major step towards vision-friendly AR glasses
22.01.2025
At CREAL, the new year marks a significant milestone! We are thrilled to introduce Clarity, our next-generation light field display, designed to be integrated into AR glasses. This transformative display empowers OEMs with a solution to build AR glasses that provide a truly natural, comfortable and healthy visual experience –free from visual conflicts and eye strain. From now on, prolonged and comfortable use of AR glasses is possible, paving the way for augmented reality to reach its full potential.
While the hype around AR smart glasses is now growing strong, we believe that for them to become everyday products, used all day, and truly augment our world (not only overlaying 2D monochrome green text), the display will have to offer fully natural and correct vision of the real and digital content, without any side effects. Those glasses being the next evolutionary stage of traditional eyewear, their primary purpose —vision correction and enhancement— must indeed remain uncompromised. This is why our light field display incorporates vision care requirements and eyewear features at its core:
Real image depth for natural visualization
Prescription fit for corrected vision
Transparent lens for social comfort
With this milestone, CREAL is proud to unlock a key barrier to widespread AR. Each component of AR glasses presents unique challenges, and the display, in particular, requires a true revolution to project lifelike digital content. Ultimately, through technology licensing and custom components integration, Clarity will enable all-in-one AR glasses to deliver a natural, immersive, and contextual visual experience.
Our new reference design is ready for testing and evaluation, and you can now get a demo of Clarity starting at SPIE AR | VR | MR next week.
