I fully support a dark mode option.
I have 22+ years of working 8h+/day on PC screens and I still have the same vision I had in high-school.
I never switched to anything white.
All that I use since MS-DOS era is on black background: file navigators, CADs, editors, excel, etc.
The direct damage vs eyes is significantly lower when using a black background.
There are other significant advantages too, including the possibilities of the color palette usage.
