I started another thread that addresses this question but I'll answer this one here too...
If you look at your screen and stick your finger really close to your face, but you keep focused on the screen, you should see two ghost fingers. They should be pretty far apart. Now if you move your finger toward the screen, the ghost fingers get closer together.
Now, in 3D video, the same thing applies. The distance between ghosts will dictate how close that object seems to you. The Evo's screen is only so big, and assuming you're holding it at a comfortable position (not 3 inches from your face), the max distance between ghosts (and we're talking about perceived distance based on arc degrees) is very small. Therefore, nothing will ever appear to be hitting you in the face. It's a limitation of the small screen and the viewing distance.
In an IMAX, the arc degree difference between ghosts can be very large, which gives the perception that the object is very near your face.
So, the perception of near or far isn't really dependent on whether you have glasses or not. It's all about the arc degree distance between ghost images relative to your eyes. If you could hold the Evo screen close to your face, and assuming the phone is still able to separate the stereo images at that distance, then you can get stuff to seem like it will hit your face.
For example, if you held the phone at normal viewing distance, and an object appeared to float 6 inches above the screen, then if you held the phone 6 inches from your face, that object will appear to to be right in your face. But you'll also be experiencing serious eye strain. It would be like trying to focus on your finger when it's right in front of your nose.
