I have heard this theory on this board for the last few years, and is very intriguing!
The upshot, if this is the issue, is I'm willing to bet 99% of this site's users will be able to, if not fix binocular issues, make it much more tolerable, by pursuing vision therapy, or in some cases minor surgical procedures.
Now to the caveat; I was born with binocular vision issues (alternating esotropia/strabismus), my eyes are as straight as they will ever be, however my brain never fully grasped binocular vision. I don't see double vision, but I definitely don't have as good depth perception as most people, also add to that astigmatism and an above -10 prescription in both eyes, and it's a winning combination 🤣
I have tried patching for computer use, and honestly haven't found much difference, at least after extended periods of time (I essentially see through one eye at a time anyway). The thing with patching is it's supposed to be a closely monitored activity by a professional as changes can occur in the binocular system if you patch a single eye for extended amounts of time.
My finger points to the industry; why would an update to software require 100% binocular vision? We're not fighter pilots. Is there some sort of pseudo-3D happening in modern tech? Perhaps the imperceptibility of dithering algorithms was only tested on individuals with an intact binocular vision system. Although strabismus is said to only affect 2-3% of the population, heterophoria is a much higher number.
So if it can be proven that we all have a binocular vision issue to some degree, we are being discriminated, in an era where technology is ubiquitous and supposedly available to people with accessibility issues.
As others have mentioned though, first and foremost everybody should get a thorough eye exam, including cross-cover tests and others such as the brock string.
