wipe0wt So basically - you might have some sort of heterophoria and would need to see a proper optometrist, who can measure for it, prescribe specific glasses and plan some sort of visual therapy with you.
Thats the best I know so far and the only thing that helped, although I am not 100% cured. I was told, dealing with this at 30 years of age, there will always be trouble, some sort of the therapy has to be done at least once a week for rest of life and even then it migh not disappear completely. But it still gets better over time.

Seagull It was convergence excess. Class of disease heterophoria, subclass convergence excess.
I am writing a series of few articles now on it, that I hope to translate soon, post on a blog and have stickied here at the top if @Slacor will allow? It will summarize what heterophoria is and options you have with it.
All in all, treatment and improvement is possible. Technology is still to blame, as I still use my old win7 laptop for movies, reading and writing with no issues. Then I use mac for couple hours a day for graphic/video work. Some days I take break from the mac for a day or two if I can to rest my eyes. However, the therapy allowed me to use the mac for hours a day, compared to minutes in the past.
So far Im the only one I know with such succes with this therapy, but more people are already working on it that I am in contact with and report improvements.
I also met people personally that have this issue, tested them with my limited knowledge. They are local so can even visit my specialist. But their line of work doesnt require computers so they dont care and are happy to know whats wrong at least.
I recommend for start - try getting a completely dark eye patch, or cover one of your eyes so no light gets in. Do this when !rested completely! with no lingering issues present from previous use of new tech (when my eyes are in pain from new technology, then even the old one hurts for some time). It should be better if you only use one eye at a time (but unfortunately not perfect). If that is so, its a clear sign of heterophoria.
Also to reply, tests to be done:
Maddox rod test for binocular vision
Near distance and far distance test of binocular vision
Fixation disparity test
Accomodation test for each eye separately and for binocular vision, also distance and near
Cover/uncover eye test
Basically all possible tests for binocular vision.
Usual issues tested by ophtalmologists go hand in hand with binocular issues, so its usual to have both, but few people ever test for both as well.
