My vision is only in perfect(ish) focus at the exact distance that I sit from my computer screen. I can't imagine that this is a coincidence.
†unless, in your case, the arrow of causality between vision and computer screen distance is in the opposite direction.
Also, with a good lens setup or with direct projection, VR/AR headsets could theoretically set the focus distance at any distance or even dynamically change it. This would also solve the vergence-accommodation conflict with current headsets.
