Just try hololens for the first time at one of the build Tour at toronto yesterday, I found when I wear my glasses, I have to hold the hololens with both my hands enable to view the view-windows, or I have to remove my glasses which makes everything a blur "in front of "me. So I don;t know if just I didn't wear the hololens right. But I really wish Microsoft can at lease learn somthing from Google cardboard that I can either wear my glasese or not to see clear images.
