Any scientific reason behind using a dark theme?

I find using a dark theme when coding in the dark is better because the bright white background won't blast your face.

light themes are better if you have a glossy display and there's some sunlight since you won't see so many reflections

I've heard dark themes can actually damage your eyesight because the contrast isn't high enough. I like white themes because it's just like paper. Black text is easy to see.

Well, there are high contrast dark and light themes.

Not scientific, but I find I have less eye strain with dark themes.

I don't have eyestrain problems on most devices, but the Retina MacBook I have at work wears my eyes out in just a few hours. I can stare at my Chromebook Pixel indefinitely without issue in the same environment.

Does there need to be? People think it looks nice. I personally find text hard to read on a dark background, some people don't.

Congratulations! You story is an inspiration.
