Lemnis develops displays with variable focal length, an important underlying technology XR. Now there is increasing evidence that Facebook bought the designs and patents of a startup.
The current design of glasses VR with fixed screens in front of the eyes means that the eyes get tired quickly. The literature refers to the so-called vergence-accommodation conflict. VR glasses with variable focus is designed to solve this problem once and for all and provide a more natural and pleasant viewing.
Lemnis specializiruetsya in Varifocal technology, and in 2018, presented a prototype with the so-called Alvarez lens.
Optical system, invented in the 60’s, the American physicist Luis Alvarez, moves the two lenses each other, providing any number of smoothly transitioning into each other planes of focus. This, in turn, leads to the natural focusing of the eye, which is reflected in a more pleasant vision.
CEO goes to Facebook
In mid-August, General Director Pierre-Yves Laffon wrote in the blog that the Singapore company “embarks on a new adventure.”
“We look forward to the solution of additional technical problems when creating the next computing platform with greater impact and unprecedented scale” — posted by Laffon.
Now Chinese news portal XR Yivian noticed that the Laffont updated my linked profile. According to the update, CEO of Facebook working in Singapore since February 2020 and in Facebook Reality Labs in Pittsburgh from August 2020.
The remaining eight employees are left Lemnis, according to the LinkedIn profile, which may indicate that Facebook took only Laffon and patents of the company.
He researched Varifocal Facebook displays at least five years and presented the relevant prototypes. At the beginning of the 2020 senior researcher displays FRL Research spoke about the achievements of research laboratory and described the problem as “solved” without saying when the technology will be market-based and publicly available.
