What I always wonder about with these Headsets is how can this not damage your eyes, focusing them at such short distance for prolonged periods. Anybody with experience in using such a device would like to comment on this?
It's not "at such a short distance" compared to how people use laptops, or even desktops. The focal distance on these headsets is all >1m (the author quotes 10 feet for the glasses they are using in particular).
