"I'm not sure, but I think my optometrist mentioned that it was quite common to find strabismic people who had difficulties when being born. Perhaps one of the professionals who post here could confirm or deny it."
How are you doing? The information in autostereograms is based on little differences between both eyes. The depth perception comes in if the disparity (diplopia) between near and far objects is different: like the Brock string: the…"
"They're all stereograms, they all function with the same principles. The ones that don't require glasses are called "autostereograms". There shouldn't be any perceived difference between them. Glasses hide extra images…"
"I think what we call stereograms are images with such patterns that allow you to fuse some of their parts and see depth (without glasses of any kind, a different method then to that of anaglyphs and vectograms).
I agree with your point about the…"
""Thinking of the eyes as two separate optical instruments suggests that diplopia or double vision should be the rule rather than the exception. Our usual experience, however, is seeing an object as single." --- then we would also perceive…"
"I've had a lot of curious phenomena with sizes. At first, after I initially gained some-kind-of-stereopsis, everything became bigger. Later, when I was doing vision therapy, things got complicated. I remember I was watching one performance,…"
""Does it come from the differences between each eye's image or does it come from the relative position of the eye muscles?"
Normally BOTH things are at work. The direction of each eye as controlled by the eye muscles and retinal…"
"mmm, I don't understand what you're saying then, I don't think there's any difference between normal and "tricked" stereo. The trick is that getting the brain to think it's not staring at a flat piece of paper,…"
"When I say point of view I mean differences in the images which try to reproduce the type of point of view differences one would find between one eye and the other in normal (not tricked) stereo vision."
"(Retinal correspondence in stereograms viewed through parallel vision would also correspond to looking far away into the distance, but as I say, changes in perspective from one eye to the other, do correspond in fact to closeness in the viewed…"
...nevertheless, in anaglyphs and vectograms, there are no changes in each eye's point of view of the object, only the position of the eye muscles changes... however, they do provide a sense of depth."
