CREAL's latest light field display fits into conventional glasses
CREAL has unveiled a new prototype of its AR light field display that is compatible with conventional prescription lenses.
Swiss start-up CREAL has been working for years on an AR display that enables natural spatial perception of AR objects.
Most VR and AR devices display digital elements in a single, fixed focal plane. This prevents or hinders natural focusing and can lead to headaches and eye pain with prolonged use (see vergence-accommodation conflict).
CREAL's light field display is designed to project digital content into space with the correct depth so that each eye can focus on it at any distance, just like in the real world.
Breakthrough in form factor?
The biggest problem with CREAL's technology was that its prototypes were very large. But over the past few years, CREAL has been working to shrink its form factor, and now it's unveiling a new display prototype called Clarity that fits inside a pair of glasses.
According to the startup, Clarity is compatible with conventional prescription lenses and offers a high degree of transparency. Natural vision and eye contact with the environment should therefore not be compromised. CREAL also promises compatibility with the OpenXR standard.

"AR glasses are the next evolutionary stage of traditional eyewear. Their primary purpose—vision correction and enhancement—must therefore remain uncompromised. This is why CREAL has pioneered a light field display technology that incorporates vision care requirements and traditional eyewear features at its core. CREAL ensures that AR glasses put vision care first before they can start enhancing our world and mind with AI-powered content", says Tomas Sluka, CREAL’s CEO in a prepared statement.
The new prototype is now available for testing and evaluation, and OEMs can license the technology for integration into products.
Clarity will be demonstrated at the SPIE AR | VR | MR Display conference in San Francisco next week. At that time, we will likely learn about potential shortcomings and limitations of the prototype.
