MP, the thing is that Mr N doesnt know any different ITMS. he doesnt feel that he has missed out, for him that is the way the world looks and his brain adapts to that ITMS. I say this from my perspective where i have worn glasses from 12 months of age and only recently was told that i have monovision lol (i have always known about the long sightedness)! i had no idea that my crap ball skills were actually depth perception issues due to my dodgy eyes hahahaha (and i could never work out the big deal about 3D movies i kid you not ).
