I have the same problem (non-stereo vision, I 'switch' eyes depending on what I'm doing). If your hubby is up for a great read from a person who was trained into stereo vision after monocular sight (well into adulthood, after having believed it was impossible after a specific age), "Fixing My Gaze" by Susan R. Barry is amazing. Working to understand her issue drove her into neuroscience, so she can explain things in plain English and 'science-ese,' LOL. I've never been able to explain "how" I see to DH, so after I read the book I gave it to him, he read it and said "OH... that explains SO MUCH" (right down to my tunnel vision when driving - "Did you see that...?" "No, honey, I'm DRIVING" - I rarely see anything beyond the road itself unless I'm either a passenger or at a red light for a while). Now, he "gets" it.MackerelCat wrote: ↑Tue Oct 12, 2021 3:18 pm
I drove DH there and back to the eye surgeon to be assessed for cataract surgery. He'll be getting it in late November and early December, which gives us time to put together the deductible, co-pay and facility fees. DH was rather cranky about the testing as the techs got hung up on his rare visual oddity: he does not have binocular vision and can switch from one eye to the other. He dislikes being talked about instead of to, so I could see why he was getting peeved.
It's kind of funny in parts because she married an astronaut - he has amazing spatial awareness and for a long time his wife had little to none.
Which reminds me, I need to see if anyone around here offers the kind of training Dr. Barry had that allowed her 3D vision. I could use improvement, if not full-on 3D - I've never had it, so I'm worried it would be such a change that I might lose my "adaptations" and end up walking into (or worse, driving into ) walls or something.
