Immy, a tech startup based in Michigan, said it has been granted a patent on a way to design a new generation of augmented reality and virtual reality products, VentureBeat reports.

The Troy, Michigan-based company said it has been awarded a patent for “natural eye optics” technology, which the company says replicates how humans see in the real world. That, in turn, leads to the most natural and comfortable viewing experience.

The Immy optical system is a direct retinal projection technology. The light rays travel through air, never entering another medium, and that alleviates eye strain.

In all other technologies, the light rays travel through refractive lenses, diffractive elements, waveguides, or holographic elements — and they all produce distortions and aberrations that can cause eye strain and headaches.

Immy’s technology enables a large field of view, as much as 135 degrees, which lets you see pretty much everything around you, unobstructed. It can also be made in a compact, lightweight package. The patent was approved on February 2, 2016.

Immy was also issued patents in Japan and Mexico. Additional supporting and utility patents have been issued for the device’s structural frame, the micro display alignment, the non-pupil forming optical path and the assembly mechanism. Other international patents are pending.
