With the rapid approach of VR, and being someone who's always needed glasses! I have been curious about this for a while.
Is it possible to correct the focus of a lens by adjusting the image on a screen. So at present the image is distorted because althought it is perfect on the screen, the intermediate lens (i.e. the one in my eye!) is faulty. Would it be possible to change the screen image to compensate for that lens.
My intuition tells me it isn't because everything is x distance away, but it would be good to get an actual scientific reason for this, and maybe what it would take to make that work (if it is / would be at all possible)
