Tunable eyeglass lenses to replace bifocals

Would this be useful for VR?

How so? To "automatically" focus on different things? Maybe with some eye tracking and foveal rendering? Seems like it'd be a more immersive experience.

Only thing I can think of is to adjust for people who can't see clearly at VR focal lengths (~1-2 meters from what I can find, which is a sweet spot for many, but not all). In that case, space around the lens exterior doesn't matter much, it could be a great fit.

Eye tracking and foveal rendering: I really hope we get that, and soon. It'd look more natural, and seems like it could substantially reduce rendering costs.

Oculus bought the eye tribe for this purpose, I believe.

I guess dynamically changing the focal distance in VR. So when you are looking at something close it adjusts so that the focal length of the eye is close.

Right now VR has a fixed infinity focal length which feels a little strange for things close by.
