As many knows on this forum, “I have trained with one eye covered, so now i can use all screens with both eye like a normal person”. That’s great! Sometimes (around 5-6 times last two years) with new screens I got tension headache. To solve that I covered my non-domination eye for 45-60 minutes, and after that I had adjust, and no more tension headache with that screen.
A month ago, I feld tension headache behind a new setup. That was a bit weird because I had already adjust to that screen. So I tried to adjust (one hour covering my non-dominant eye), but this time it didn’t work to my surprise. Not good news.
I trained more with covering my non-dominant eye, no difference. Still tension headache. Plus another problem: stiff neck, back pain, left thumb numb and tinnitus in left ear. So it's probably a nerve from the visual center that causes that, or how it happens.
So my new goal in life is to solve this.
After 2,5 weeks I tried something that haven’t worked before. I covered my dominant eye (instead of the non-dominant) one evening. The non-dominant eye is a bit blurry after a day behinds screens, and this training doesn’t feel as good as with the other eye. It takes two days with that training before I could tell it makes a diffrence, and I am adjusting. I took approximately a week of training before it works good with both eyes.
Conclusion, don’t give up! Try new things, and maybe you will find something that works.
