I just created an account to share some things that have helped me in case they haven't been discussed yet and hopefully they can help at least somebody.
Background / Symptoms:
This has happened to me twice. Both times I was under extreme amounts of stress. The first time, I put all my savings into a project and was working 14+ hours daily, 7 days per week for months, all the time under constant stress. After buying a MBP Retina late 2015, I just couldn't look at the screen without experiencing pain, this translated to all screens and included light sensitivity in general, sometimes I couldn't even be outside when it was cloudy. I went to multiple eye-doctors and the conclusion was MGD - use warm compresses and eye drops until it gets better in a few months. I took a long 6 months break from everything and just enjoyed life, after that time, I started a new job and could work normally again on different MPBs.
5 years later, a very similar situation happened, but it didn't go away, even after 1.5 years. I decided to try different things:
Things I've tried that led to success:
- Vision Therapy (I read that it helped some people, so I wanted to try it) so after a lot of trial and error, I finally found an optometrist that specialises in that. My eyes are naturally pointed a bit outwards and one is pointed slightly down (but I never had any problems). He said it might be the cause, so I gave it a try.
- Psychotherapy (in case it's psychosomatic). Some keywords, in case you're not familiar with the topic: chronic pain, TMS, Curable app, neural pathway pain. A lot of people have different kinds of chronic pain and symptoms, mostly because of repressed emotions. If you're thinking that's not your case, just know that you're not aware of repressed emotions, they're repressed subconsciously, before you're even aware of them. Maybe it helps to think when did the issue begin, did something significant(to your emotional state) happen in that time.
- I went to a fancy optometrist center, where they scanned my eyes and found something that they were sure was the issue. By other optometrists, I only had a slight +dioptry, I never needed glasses,… When another eye doctor put numbing drops into my eye and then measured the dioptry on the machine, it was +0.25 more than without the drops. But that scan revealed something more - my lenses are not symmetrical, they're slightly thicker in the middle and in addition to that, the surface looks like a golf ball, resulting in different dioptries all over the place, so in some places it was very high, even double that what was measured in any other test. He prescribed me some reading/computer glasses with roughly double the dioptry/cylinder than what a normal test would show for me. After trying this when my eyes were "still sensitive to everything", it didn't help, so I thought that's not it.
So, it might be one particular thing, or a combination of all of that, but after a year of doing all of the above, I'm happy to be back to normal, but with glasses when working on a computer.
I hope this helps somebody.
