Diplopia, aka double vision

[pw...@yahoo.com]

Some months ago, I started a little research about this topic, as it
relates to tropes and found some images on the web that simulate what
double vision is like. Here are some I found (the search terms I used
were 'double vision' or diplopia):

I'm an exotrope, though, and I think the images I found more simulate
the angles that an esotrope's eyes would have than an exotrope would.
