Nearly two years ago, Wearality created a unique Fresnel lens for VR headsets offering a claimed 150 degree field of view. The company successfully funded a VR viewer featuring the lens called Wearality Sky through Kickstarter. The company recently revealed a new and improved lens, but this time around they intend to act as a supplier rather than directly selling a viewer to consumers.
A thinner lens means less weight, but Wearality also says that the optical properties of the lens can create much smaller headsets.
