Oculus Research's focal surface display could make VR much more comfortable for our eyeballs

The current generation of VR is great, but it's far from perfect.
One way VR falls short of the real world is the fixed focus distance. Despite the illusion of depth from the stereo images you're looking at, each image is essentially flat, at a fixed perceived distance from your face, and with a focus selected by the game engine instead of your eyeballs. This can lead to fatigue or worse kinds of discomfort, and also puts limits on developers who need to strive to keep content in a visual sweet spot and a constant focus distance or risk discomfort for their users. Oculus Research is showing off a solution to this problem at SIGGRAPH this year. They call it a "focal surface display," and have already built a working prototype. The technology puts something called a spatial light modulator (SLM) in between the screen and the headset's eyepiece lenses, and the SLM actively bends light to give a scene a 3D contour. The edges of this "focal surface" aren't very sharp, so they also do some color tricks to correct for the distortion.
