You really must try it. Some people don't seem to like it much. Since I was using it, some 3 years ago, I am sure things have moved on. Then, there were all sorts of problems which were caused by over ambitious programmers trying to push the computer systems to do more than they could handle. With the speed of machines today, I guess most of these problems would have been ironed out.

The term 'properly' is quite hard to define in your case. If a person with monoscopic vision said that they can see the _real_ world properly, then they will be able to see the virtual world properly.

The world is rendered for two eyes. To see the world 'fully' or 'as intended' you must have stereoscopic vision.

Essentially, a person will see the virtual world with the same 'fullness' as the real world. Those compensations made my monoscopic visualisers will apply in the VW as well as the RW.

It is also true that most headsets have enough room for a pair of glasses.

As I have said, you will appreciate the Virtual World in the same way that you appreciate the Real World.

Hope this helps.
