VR goggles and headsets have their glass screens about 2″ or 3″ away from the eyeballs. But many people can only focus on things that are at least 6″ or 8″ or 12″ away (especially adults). How does the brain perceive the goggle images to be in focus?
If there are tiny words shown on the goggle, can the viewer read words on the goggle easier than if the same words were viewed on a piece of paper the same distance away?

It’s like a backwards telescope. The lenses in VR glasses are shaped in such a way that the content your focusing on appears at distance. It’s not like looking at a flat TV/phone screen
They have lenses that focus the light. To your eyes, the image they are receiving is coming from further away. This does mean that you focus for the same distance even when things appear to be at different distances. The “distance” info comes from the angle of convergence of your eyes. The fact that this doesn’t match up with the information about how far away you’re *focusing* is one of the things that can cause motion sickness/headaches/etc, and one of the hardest problems to solve.
