The white background is fine for the eyes, so long as the brightness is set properly - minimum brightness for the surrounding lighting with medium-high contrast. IME, this setup in a well lighted office makes a marked difference in eyestrain at the end of the day when compared to dark modes, dark rooms, and high-brightness light modes.

It's totally individual though. Back when we finally got terminals with white background I was very pleased. A co-worker was completely unable to use them though - he had to set the terminal to reverse mode. We talked about it and it was clear his eyesight was completely different from mine. There's no "one size fits all" here, and I for one have problems with dark mode - I see "flares".

This is precisely why I use f.lux[0] on every computer. As the blue light is reduced toward evening, the screen becomes much less bright. Works great for eye comfort and is maybe even beneficial for sleep.
