	I did not quite understand the nature of your daughter's problem with
vision, I am not an ophtalmologist, I simply suggest that you use a
View-Magic viewer, a couple of stereo postcard prints (each view in
4x6")
and you let your daugter try to find the right position of both prints
on the table 
by herself. If she only has eye convergence problems, she will find.

Thanks for your observations. I am not looking for an expert on eyes and
their optical correction. Rather, I am looking for someone who can
advise
on how to go about designing a viewer composed of two separate optical
paths. In the normal viewers that are frequently discussed on this list,
two monoculars are fastened together at the normal interocular distance
and their optical paths are parallel. My special viewer would
essentially
be the same two monoculars, each of which could be separately aimed on
non-parallel optical paths at the 3D photo appropriate for each eye. My
daughter with divergent vision (double vision) needs a viewer that would
enable her to see simultaneously the 3D photo appropriate for each eye
and, hopefully, then be able to merge them mentally into a three
dimensional image.
