This is my first long post on ledstrain. I live in Sweden and I don't usually write long texts in English, so bare in mind with my english.
In November I did something that made me able to use newer screens much better than before. Previously, an early-made iPhone 4S with iOS 7.1.2 was the only smartphone that worked satisfactorily + a HP notebook with win 7 and CCFL display from 2009.
Like many others here on the forum, I have problems with "newer screens". The first time I became aware of my problem was September 2011 when I bought a new Sony notebook with LED, 4 hours behind the screen gave tension headache for 8 weeks! At that time, I didn't understand what had happened, it was a bit scary. For a while I was afraid it was a brain tumor, but after a brain x-ray it was excluded.
I went to several ophthalmologists, specialists, etc. without any result. This was around 2012-2015, at that time I thought there was no difference to look at screens with one eye or both.
I notice as many others here on the forum that upgrading software, firmware, drivers etc. can mess it up. I upgraded the software on my LED TV from 2011, resulting in that I couldn't use it. Fortunately, a colleague had bought exactly the same model and not upgraded the software. So we could switch TV and it worked again. At the same time I noticed that my girlfriend's parents' LG plasma TV from 2010 with digital TV tuner didn't work, but analogue TV tuner worked on it. So every time I visited, they switched to analogue until they switched to a new TV and I couldn't watch anymore.
It's not just phones, computers and TVs that don't work. In 2014, we visited the newly renovated Madison Squre Garden to see when NY Rangers played. I couldn't finish watching the match, my eyes was hurting so much and I just wanted to blink my eyes all the time. It got better when I
left the arena, and took about 2 days to recover.
In the autumn of 2014 i overworked my eye muscles behind a screen, that took nine months to recover. In addition to tension headaches, red eyes, dizziness, I had pain in the back of my head and it extended down to my shoulders when I tried to work. This meant that I could work 20 minutes in the morning, 20 minutes in the afternoon and 20 minutes in the evening on the computer I had previously been able to work full time on. This time was tough for me, both private and job. But at the same time I became a father and got something positive I could focus on.
During 2016-2018 I noticed that some newer lights from IKEA etc. didn't work. A newly built restaurant where I live didn't work, etc. Some newer cars do not work.
In autumn 2018, Chrome was updated on my computer, 1 min on the Google Analytics site provided tension headache for 1 hour.
"The day after Black Friday 2018", I have read on the forum that it works better for @martin with one eye when he is photographing with his camera. So when the family had gone to sleep, I covered my right eye. Then I tested a newer iPhone. After 7-8 minutes of use, that iPhone would give me tension headache for several hours. With the covered eye I could manage it for a whole hour with just a little stinging feeling in the eye. I could barely sleep that night, it felt like I won a million on the lottery. A few days later I tested with the other eye and it worked just as well.
I continued to sit about 1-1.5 hours a day for about three weeks with the same iPhone and covered eye. Then I bought a pair of gaming glasses, where I was going to cover one eye. But I tested them before covering and to my surprise "it worked". Sure it stings in the eyes and they gets a little red, but I hardly get any tension headache.
So in three weeks, I have taken a giant step in the right direction. So I switch to the newer iPhone, which I can now use about 2-2.5 hours over the whole day. Sure, my eye muscles are hurting a bit and my eyes are a little red.
I get some tension headache and dizziness from other new screens, but it is much better than before. Now I can use Google Analytics in Chrome again.
In February, I visited an optician who states that "Close-up, your eyes have difficulty working together and the brain prefers to choose one or the other eye. The closer you look to different objects, the more difficult it becomes. the brain chooses to shut off one eye and then you get a distinction towards the nose. I ordered two pairs of glasses, a pair of mobile/computer terminals and a pair to "sit on the couch and watch TV". I have used the glasses on and off, but they do not seem to make any difference.
In May, I flew down to Prague and met @martin here on the forum. Firstly, Prague was nice and I can recommend it to anyone who wants to go there. But what was the most impressing was to meet Martin. A very nice and ambitious guy, who has spent a lot of time trying to solve "our problem". We met two evenings and exchanged experiences. The second night Martin had a string with a little ball. I kept the string in front of my nose and focused on the ball about 40 cm in front of me. What happens is that the string is broken at about 38 cm. My eyes focused too early, it seems to be the same problem that Martin has.
So now my goal is to find a specialist, I got the following text from @martin "they should test for vergence (convergence, divergence) excess or insufficiency and also for accommodation problems both on one eye and two eyes work. and training and know the tools such as brock string, tranaglyphs and red / green glasses, flippers and livesaver chart. "
Some other notes:
- When I have had sinusitis, my problem has become much worse. What I have understood may be such an infection affecting the eyes. Unfortunately, I think I now have a "chronic sinusitis". Should examine it with a doctor, but I use a lot of nasal spray nowadays.
- In 2002 I made a Lasik, was near-sighted before. First made one eye and the other eye after seven weeks. Successful results.
