I just tried one of those devices,the one you put a mobile in.
This was done purely to see how I could use a VR with glasses,didn't like it.
How does the vive or oculus behave with a user and glasses?
What didn't you like about it?
My brother bought an Oculus didn't like it because of the resolution and then sold it.. Since then he has tried a phone VR headset with a 1440p screen in it, found it clearer. But then realised he never tried his OR with glasses on. [where is it]
Now he wants to try an Oculus again WITH glasses and might buy one.
(Yes, more money than sense)
Probably a bit too anecdotal for you to make a decision on?
