AGI Yes, like 2 months ago I once again wanted to know if there's something wrong on the eye level despite previous doctors always saying "you don't need glasses" and after having visited 3 neurologists and an alternative practitioner, all who had no idea either and had never heard of the problem. This time with very strong eye drops the eye doctors measured 2.0 dpt, but some days later with +2.0 test glasses I couldn't see sharp at all at a distance of 2 m and more. So their plan is to slowly let the eyes adapt to increasing diopters.
Until the sight is 100% corrected I can't be sure the cause of the eye strain is not the eyes. Which I always thought up until 2 months ago.

Since this was the first time I was given vitamin drops for my eyes, I was checking on what they could potentially do. I bumped into this article
From memory the only thing that I was told was eventually off in my blood exams a few times was vitamin D.
Does any of you have the two, low levels of vitamin D and dry eyes?

The eyedrops I was given pretty immediately soothed the twitching of my eyelids and made looking at the display more comfortable. Happy but surprised/curious, I played around with Google Translate and Google. The product description says "This preparation of vitamin B12 improves muscle function related to eye focusing. It is usually used to treat eyestrain." The active ingredient is cyanocobalamin. I thought it were a drug, but according to WebMed "is a man-made form of vitamin B12 used to prevent and treat low blood levels of this vitamin".

Very similar goes for horizontal heterophoria.
degen What is the name of the eyedrop?

This is a good article - https://www.aimu.us/2017/12/10/heterophoria-symptoms-causes-diagnosis-and-management/
It also mentions miotic drugs (eye drops) help to some degree, and explains why. I am more and more convinced that all of us here have some far than normal degree of heterophoria.

@AGI Continuing discussion from the other thread.
The Sancoba eyedrops have regulatory approval in Japan to treat asthenopia. My product (Bausch + Lomb Vitamine B12 Chauvin) has a different indication in France. The only difference between the products as far as I can tell are the inactives. I ordered it online and yes it is a medicine. The Sancoba eyedrops are considered a medicine as well, but at least your doctor has indicated them for you.
Id like to leave this here, good summary with multitude of options: https://green-club.eu/wp-content/uploads/CET-51114-Investigating-and-managing-heterophoria-.pdf

martin Thanks for the info.
"If decompensation occurs in childhood, the child will develop a manifest strabismus, suppression will occur to overcome diplopia and binocular single vision will be lost." This is me.
I have had these issues all my life due to premature birth, and have alternating esotropia. I have had multiple surgeries to try to correct my squint however even within the last year when speaking to my surgeon, he stated that it could improve my eyes cosmetically, however binocular vision will not be possible, and there is always the risk of over correction, which would look even worse.
On top of this due to my premature birth my eyes are irregularly shaped, which will change how light enters and hits the retina. (Astigmatism?) Also pretty short sighted (approx -8 left eye -12 right eye).
Just saying as somebody who has always had these issues, and used all screens OK until >2012, it's not my eyesight that is causing the problem.
However I agree that everybody on this forum should get a thorough check-up with a specialist.

diop Well its quite obviously both, otherwise everyone would have an issue when new tech was introduced. When someone figures out a tech solution, Ill be happy to pay them for it. I dont see that happening anytime soon and the eye therapy helps, so Im going that route. I want to get to a point where I dont see a difference in comfort, be it tech solution or health solution.
@KM how is the progress with you farsightness correction?
I have the same "hidden" +2 farsightness diagnosted when my eyes where on special eye drops, and currently starting to correct it with +1 contact lenses. I did feel an instant effect while wearing these and using a "bad" screen - it definately felt differrent, a lot easier to eyes, although my eyes were still getting tired, but without severve eye strain.
I also have similar to @martin's esophoria problem and finished treatment course on synoptophore recently.
coach789 The glasses don't help much so far, sadly. And I still get that "eye strain within seconds" from certain displays or lamps. I noticed the eyes have relaxed and there appears to be more prism diopters now. I probably should make another appointment soon. But I have no idea where this leads to.
__528491__ I noticed my symptoms about 2 years ago in 2017. I wan to multiple PCPs (primary care physicians), optometrists and ophthalmologist with no luck. During one of my PCP visits I mentioned how my ears feel like they are always clogged. He suggested going to an ENT to get checked out I had seen a few users here say they had sinus issues and after getting surgery their eye strain greatly improved (reduced?). I had tubes in my ears when I was really young but never had sinus issues, only the typical seasonal allergies. During my first visit to the ENT he said my sinuses were so clogged and swollen that he couldn't even look at them. He sprayed some medicine in to reduce the swelling and was finally able to see. Turns out I also have a deviated septum and the wider side is being blocked by bon. He was surprised I didn't realize I wasn't breathing right. I told him I'd like to avoid surgery and try all other possible solutions first. He prescribed a nasal spray meant for allergies which I use twice a day as well as take zyrtec. It hasn't fixed my eye strain and I'm honestly not even sure if it's reduced it but I continue to use it just in case. I try to avoid "bad" devices as much as possible
I did do a test and took afrin (which I heard is pretty much just steroids and shouldn't be used long term) and used my wife's computer which is a known bad machine (latest windows 10 build with a gtx 1060) and I was able to use it longer than usual before the strain kicked in. I think I made it about 30 minutes before I really felt the strain.
I don't know if this helps but I noticed we all have a lot of different triggers. For example most people on this site can't use the latest macbook pros. I can use a 2019 macbook pro (no dedicated gpu) for hours. It's not as comfortable as my old windows 7 laptop but it's no where near the pain I get from windows 10. One thing I did notice with the macbook pro is if I plug in 1 external monitor I don't have an issue but if I plug in 2 external monitors I start getting strain. I'm not sure if this is because the 2nd monitor is plugged in via a 3rd party usb-c to hdmi adaptor or because the 8th gen i5 integrated gpu has to work harder causing the strain.
