> you can feel your eye muscles release tension when you go from light to dark mode

For those like me, i'd like to add, this is not universally true. For some, dark mode will provide a significant reduction in comfort and increase in your fatigue and other symptoms.

Quite a few years back now, I started having significant problems with my eyesight that for the longest time I failed to match up to the switch to significant dark mode usage.

Turns out for many (though perhaps not all) with astigmatism, dark mode can induce issues that will wipe any potential positive impacts normal people experience. In my case, it gave me horrific blurryness/double vision that I thought was my eyes developing some new problem.

I'd tell the eye doctors "it seems to start fine then get worse as the day goes on!"

No, in fact what was actually happening, was in the afternoon my machines were scheduled to start shifting to dark mode. At which point the issues would start and my eyes would feel "heavy." It would fatigue my eyes so heavily that even not looking at displays would be affected.

I can not believe it took so long to connect the two, but I never even considered dark mode because it was so heavily pushed (along with reductions in brightness) as the answer to general monitor usage fatigue that I never remotely considered it may do the opposite, which to be fair, is on me.

Point is...if you have astigmatism, verify for yourself before rolling over to the full commit. Hopefully you are fine, but if not, you'll know why.
