People generally tend to blink less when looking at a computer screen, as low as 3 times a minute as opposed to 15-20 times a minute otherwise. ¯_(ツ)_/¯ when you're deep into some code, it's difficult to remember to blink, seeing as we never have to think about it away from the computer.
As per the vast majority of developers.. it's dark IDE all the way. I've also started to use dark reader for my browsers and darkify-ed my slack. Dark themes generally help with strain and the environment light/dark contrast. Also I believe light text on dark backgrounds is easier to read.
