"blue light is harmful" is a highly debated topic. Iirc there is no consensus yet and some studies indicate that it's not a health risk. Apart from that, having a screen that is too bright can certainly cause problems. Especially if the contrast is very stark to the surrounding environment. I personally use a light theme when it's very bright outside/inside and a dark theme when it's dark + my monitor brightness at home is set to ~70% which is plenty.
