3D

I have started to notice more and more new movies and games advertising 3D recently. I don't actually know what they mean by 3D considering that I have an eye condition causing me to be unable to focus them together correctly, the last time I remember being able to see something in "3-D" was back when they had the goofy red and blue plastic glasses which produced blurry people to slightly pop out of the screen towards the viewer. This new 3D trend is aggravating me now that I see that a lot of my favorite games are going to be coming out in 3-D on new 3D consoles which means that I will have to pay more money for a device that I cant fully enjoy although others have told me things like Avatar in 3D were quite astonishing.
