Actually I have no idea why that happens. Maybe there are some scientist out
there who understand it?

You are right. it is very difficult to understand. I think that if I became
blind i would have to change quite abit. Maybe my ways of interacting with
others would have to change - and maybe I would have to become more aware.

I guess that being blind in one eye it is something you have thought about
alot and understand well?

It is the distances that the identical characters are spaced apart which
determines how far or close the characters will apear when viewed
stereo-scopically. The closer together they are horizontally, the nearer
they project stereo-scopically. The further apart horozontally, the further
back they appear. Somehow the brain is able to capture all of this
information simultaneously (There are limits to the range of variation in
depth which can be viewed simultaneously though) - to create a very vivid,
multi-layered image. The characters in the for-ground, and those in the
background, have the same degree of detail. Somehow they all appear more
vivid.

Does it get tiring having to see things through one eye? Or have you got
used to it?
