I kept the "good" fridge downstairs. Sadly these things have a limited lifespan - you can't keep fixing them forever, and it looks very ugly in the kitchen, so I'm tolerating the new fridge for my wife's sake (but I keep the screen off as much as possible, yes it's a Samsung with the screen in it!)
I'll keep persevering. yesterday was pretty ok, today feels even better. I just have been limiting LED exposure and trying to force myself to sleep and take breaks. Yesterday was my first full day back at work and it went… ok. Not perfect, but by evening I was pretty good to go.
I also started experimenting with binocular vision as a way to reduce eye strain. Covering one eye and forcing myself to focus was VERY helpful. I have a new pair of eyeglasses that I haven't started wearing routinely yet because the new prescription is difficult to get used to, I probably need to accelerate the timeline on that.
Stress/anxiety makes this 100x worse. It's definitely brain related. We need to stay strong, here.
As for the supplements - I think it's holistic. No one supplement is a magic bullet. I think that the saffron/lutein/astaxanthin/zeaxanthin do offer some blue light sensitivity protection, but it has to come in addition to overall de-stressing. Magnesium helps there, as does just getting enough sleep. And a little whisky. And the occasional CBD or THC or Kanna.
