Whilst what you are saying, in theory, is correct, in practise things are a little different here. In real life, at 3 metres, I can see every grain of dust on my tv stand (Which I really should clean) with perfect clarity. I do not wear glasses for everyday use. I do, however, wear reading glasses. I own an Oculus Rift, and use it perfectly without glasses. I can barely make anything out inside the
DJI Goggles without reading glasses. And my reading glasses don't agree with the focal length, so it is now just "less blurred". I, too, shall have to experiment with reading glasses of varying focal strengths. A simple focal adjustment, and we could have all been happy.
