Justed wanted to wish you well for your surgery.
I have never been able to see in 3D. I have no depth perception but for the most part I don't have any problems.
3D movies are lost on me...just make me nauseous. And those little Viewmasters..same thing...lost on me.
There is an interesting book you might want to read. It is called "The Mind's Eye" by Oliver Sacks. He relays the story of a woman who never saw 3D (steroscopic vision) until her 50's...fascinating. Makes me think I am missing alot.
