Sorry to hear of your situation!
I was fortunate in the Dell Latitude 5280 Laptop that I use for work (with the night light on 100% and adjusted for brightness) did not cause me significant eye strain (except from the monitor being very small -- that's a different issue) until Windows 10 recently underwent a "re-image" with a message that the old graphics driver was no longer supported and thus removed. The funny thing is I don't see much of a change to the screen. However, I do feel it quite immediately when I'm using.
As such, I will see if I can use it with a projector as another poster suggested. I'm hoping by not facing the monitor, I can avoid the light from the monitor shining directly into my eyes although it's not bright at all -- I probably could use it at a higher setting for better visibility. Also, I hope by having a larger image, I can sit farther away, not needing to use close-up vision as much. (The small screen is rather hard to see, which causes regular eye strain, but that doesn't have anything to do with the light emitted from it or the issue we're talking about here).
Beyond that, I might spend the money ($1,000) for some Neurolenses. I hesitate, though, because in natural light, I don't need a prescription. Also, I don't think it's just an eye issue, although I do have severe dry eye.
How I wish I could go back to the original setting! However, I am prohibited from doing so because of my work.
Good luck in your search for an answer! Please keep us posted!

Other Ideas:
FL-41 Filter Added to Rx Glasses or Alone (If no coating on existing lenses, can be added for about ~$40).
F.Lux or IRIS for computer.
MSM Eye Drops.
Check if overhead lighting makes your symptoms worse. I can only use incandescent with a shaded desk lamp (and natural sunlight).
