ELI5. I am near sighted and wear contact lenses. I also just finished Half life Alyx in VR. I tried playing without my contacts, but it was as blurry as ever. Why? Since the screens are so close to my eyes.

And also, could my vision potentially be fixed within the headset if I could somehow input my prescription and adjust the focus? Could it also work for far sited people? Thus allowing people who wear glasses to play in VR?

The lenses make everything appear like it is about 2 meters from your eyes, this is actually the cause of the visual distortions most of us get when we first play vr - two parts of our brain are interpreting the distance differently.

It's also why if you hold things close to your face in vr they become blurry, even if nearsighted.

I am far-sighted, and it's amazing to see things a meter away in full detail again without glasses (I don't do contacts) .
