My own test on myself, suggests mine is much wider than that close to
200 degrees. Raise a finger of each hand concentrate on the PC screen,
move the hands back at either side of the head, until the fingers
disappear from view - 200 degrees.

I'd say that was about right. (mine is about 140 degrees of course)

You can't see directly to one side when looking straight ahead?
