Dear Friend,

Since I was on the 'receiving end' of using
stereograms for "controling" intermittant strabismus,
I will and this commentary.

The training as support, and practice "fusing" was
excellent!  It is tedious, but if you learn how
to use them -- they are great.

In fact I can "fuse" two images (the same) when
placed side-by-side.  (Takes practice.)  This
is where "visual training" truly pays off -- you
learn "control".

Hello

I've been interested in stereograms for a long time now, however I seek

some information:

- If they are good for the eyes

Otis> For me, (with medical support) they were the
"right idea" at the time.

- The effect of viewing stereograms on the two brain hemispheres.

Otis> Difficult to say.  The person learns to "notice" when
an eye "drifts", and brings it under control himself.

- Benefits for health of the eye between viewing in crossed-eye or
parallel-eye view and which is better

Otis>  This depends totally on the person.  For myself it
was the "spur" to pay attention to my vision, and
control "fusion" myself.  The practice was
a great help.

- Can they be used for therapeutic use?

Otis>  They have been -- for the last 60 years.

References to backup your comments are highly appreciated.

Otis>  In the doctor's office -- and from my own experience.
