Somehow, HTC managed to achieve this with plain old Fresnel lenses. All I needed to do was set the graphics to Auto in Vive Hub on my desktop and the Focus Vision gave me true 5K PC VR at 90hz ...

We propose an algorithm for simulating matrix parameters suitable for mass- manufacturing the microprismatic plane-focusing Fresnel lenses. These specialized lenses create a homogeneous light spot at ...

An algorithm has been developed for modeling the parameters of microprismatic specialized plane-focusing Fresnel lenses. Such lenses are more effective for application in photovoltaic modules compare ...

Aim To determine if ‘Defocus Incorporated Multiple Segments’ (DIMS) spectacle lenses slow childhood myopia progression. Methods A 2-year double-masked randomised controlled trial was carried out in ...
