With a lazy eye, the brain tends to just outright ignore the conflicting signals and you end up only seeing out of one eye. My guess is that the IPD was the primary problem for everyone else. That's real easy to get wrong and it can cause massive eye strain as your brain tries to force your eyes to focus on an image that is geometrically impossible to focus. In your case, you probably ended up just using one eye and your brain filled in the missing data. That way you sidestep the focusing problem.
