Since we're commiserating: the vergence of my eyes is failing and I'm not even 40. My actual vision is perfect; better than ever. But apparently my eyes don't converge so well anymore, giving me horrific headaches if I look at any kind of screen for more than a few minutes :( Really sucks. Doc gave me prism lens so I can use a computer again, but they're exhausting to use. Hoping I can find a specialist after the pandemic is over and figure out a better option; really don't want this to get worse. Kind of sick joke, considering I spent almost a decade of my career doing computational imaging and computer vision work. 2020 :/

Wonder if a VR headset with a custom interpupillary distance (IPD) would work for you? eg set it to a distance that's not physically correct, but er... more correct for how your eyes operate. If it's works, you'd be able to read text again. You'd just need to do it from inside VR. ;)

Look into IIH, 5th or sixth nerve is affected, causes double vision. Diamox fixes my double vision. Before that I was using prism glasses.

  6th cranial nerve palsy is what got my vision. Unknown cause. I chanced it with strabismus surgery and it has really paid off for me.

    How did you know it was that? I've had a quite sudden change in vision (I used to be able to read without glasses or function daily without glasses, and in a matter of weeks or months I suddenly needed glasses all day, I'm 37) and it seems my astigmatism progressed, but not that much since before. I also had quite bad posture during the confinement and wonder if I could have pinched a nerve?

      Hard to say. Sudden Eye strain caM weaken the eyes. In my early 20s I tried to focus on something really hard. Then “owe” I couldn’t focus at all. Apparently I had needed glasss for years, and that was the final straw.

  I'll definitely have my doctor take a look. Thank you. It's so hard to find information about possible causes for convergence insufficiency. All my Google diggings have come up with the usual information about treating it in children :/

    I was referred to a child eye doctor, as apparently no one bothers with adults. Never made it due to covid. Diamox was almost an over night fix. That’s when I put it together. I had to dig like crazy to learn about cranial pressure and sixth nerve. Eye doctors were all clueless on it. Even Neurlogist mostly were.

Contact this guy. It looks like a non-surgical solution may be possible : https://media.ccc.de/v/35c3-9370-hacking_how_we_see Essentially, they use a VR headset to offset the shifted vision, and then gradually correct the difference in therapeutic sessions. Pretty ingenious.

  Very interesting presentation, thank you for the link. I'll have to look and see if they've made progress since then; something I can try at home perhaps.

  Looks like the project has been silent since May. Hopefully they'll resurface after the dust from the pandemic settles.

I had something like that and doing a few minutes a day of magic eye / 3d stereograms sessions helped me a lot. That consisted of learninng how to see them then learning to hold the image up in 3D (feels like starring behind the image) then rotating the eyes around while holding the stereogram in focus (looking at all parts of the image not just center). This helped strenghten my eye muscles and tension/headaches went away.

  That's good to know, thank you! I printed out a Presbyopia chart (http://www.robert-silverman.net/presbeninst.htm http://www.robert-silverman.net/presbeninst.htm) that was linked on HN awhile back and started using a Brock string. Figured I'd do those until the pandemic is over and I can get some professional vision therapy. Guess I'll pick up a magic eye poster too. At least it'll be more fun than staring at a string for five minutes.

    There are tons of magic eye available as images online. Not all magic eye images are equal and beware they all have different depths and some are more visible and pop up faster than others. Some are particularly pleasant to stare at. Btw, there is even a magic eye tetris out there. Playable only when one is proficient at seeing magic eye images.
