Hii Leon, I have a trick i use to get my eyes started. Look at the pair of images full screen on the computer monitor. Then hold your index finger or a pencil up in front of your eyes, quite close, (about 15cm away for me), and focus on the pencil. While focussed on the pencil you can see in the background on the computer monitor, a third image sort of appears between the two "real" images on the monitor. Try to shift your focus from the pencil to the "arrow" that points to Pluto in the middle image and at some stage you will suddenly see that arrow sharp and clear. Your eyes are now sort of crossed but really are looking at that third arrow. The middle image now has that 3d depth. It might be fleeting at first, and your eyes wont feel comfortable but concentrate and slowly shift your focus from the pencil to the middle arrow. Hope it works for you,
Mark
