Seriously I am very confused about this. Some people say how blue light works good for them (therapy, blue tainted glasses,...) at the same time I see people and doctors telling me that blocking the blue light could be good.

Am I missing something or are things indeed that confusing? For example, you see an article like this (not about concussion):

But then you see many articles saying how blocking blue light can make you relax more, less alert, more able to sleep. In fact my understanding is that screens (computers, electronics) are advised against for most people with insomnia exactly because of they emit blue light.

I was going to stick with orange tainted stuff, lilke the feeling, but heard stories including on this forum how blue light therapy and blue tints help them a lot.

The only way I can make sense of this, is if somehow blue light is good during the day and at night switch to blue blocking eye-ware.
