AGI I am happy to answer all questions. First, I am from Sweden so the medicine is the Swedish variant. And because English is my second language it’s not perfect in writing, but understanding is not a problem 😉
For some years ago I started with the nose spray Nasoferm, because my nose got blocked of screen usage. Its decongestant, in Sweden you take it if you have catch a cold. It worked ok, but not great, and i got addicted. So I visited my doctor and she said that I got to stop taking that nose spray because its not good to take more than some weeks, for me it was like a year. So she wrote out a receipt for the medicine Rinexin, which is for sinuses. One pill in the afternoon everyday that i look at screens, which is like everyday. Now I have take it everyday for almost two years i think, except some days in the Gran Canarian sun. It’s much better than the nose spray. But you get tired, and it disturbs sleep.
I have trained much the last two years with one eye, so tension headache is like gone. But my eyes begins to burn a little in the afternoon and gets bader i the evening. With Rinexin i can handle the afternoon pretty good and gets less burning in the evening. Some evening with much screen usage its bad, but then we are taking about like 12+ hour of screen usage that day. Also my nose don’t get blocked with Rinexin, so its like a little miracle.
I have no allergy. I have the same problem all the year. But it gets worse if i catch a cold so my sinuses go bad. So looking on movies in the bed if i catch a cold is much worse then when i am well.
If have been to a ears-nose-throat doctor, he toke a little camera and put it through my nose. He couldn’t see any problems, and he is one of Sweden’s best doctors in his field. So back to the drawing board again.
My theory is: My brain sees, but not my eyes, what happens on screens. Like dithering and flicker. It then sends signal to my eyes to adjust. Because I have done Lasik my eyes is changed and my brain don’t know all about it, or maybe i have had some problems with my eyes all my life. When my eye muscles adjusts, or what is adjusting, i think it adjust to much with repeat and makes the problem.
