I know that my eyes are not very good as I see my doctor every month.
I would like to think that my brain has made a lot of compensations for
my poor vision, but if so, then either my brain is getting worn out or
my eyes really are getting very poor. :-)

One thing that my ophthamologist does not seem to be able to pin down
is a particular problem that I have had since childhood.  Every now and
then the "levels" of depth get all confused for me.  One example is
that when I look at characters on paper quite often the characters jump
out from the paper and look like they are floating about 2" above the
paper.  Another example is that I often see colours at different
depths.  I have been tested for depth perception and have been told
that my depth perception is extremely acute as well as my colour
perception.  Alas this makes up for the fact that my resolution and
convergence are abyssmal. 

I have seen some of the stereoscopic movies and have had an extremely
hard time with them.  Sort of like the crazy cartoons that try to
exaggerate the depth by making things look like they leap out at you.
I can't remember the movie, but in one scene a roller coaster was
coming towards the viewers with the intent that the audience would
experience a holographic sensation.  Well I almost had a heart attack.
After picking myself up off the floor I noticed that noone else had
reacted the same.
