I am unsure wether you are aware that the screen is only physically 5cm away. But our eyes have to focus (Focal Distance) on a distance of 2m (oculus quest 2) or infinity (vive) (afaik, i'd love to get more detailed informations on what glasses have what focal distance). This is archived by the fresnel lenses used in the vr glasses. So it's not the problem focussing something in 5cm distance. The big issue is that your eyes never have to adapt the distance they are looking at. Watching a screen all day 50cm from your eyes is equally bad. You could say that focussing a distance 2m or infinity is better, but i am no eye-scientist.
