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.
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.
I printed out a Presbyopia chart (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.
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.
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. ;)
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?
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 :/

2020 :/
