How do you like blue light glasses?

I think you already know this from the internet or from somewhere, it is these glasses that we should wear when we look at the laptop, tablet, etc.

do you have one and if so do they work at all?

You mean the glasses that filter blue light? Since I wear glasses anyway, I got a coating on my normal glasses from the optician. It's easy to notice that blue tones are perceived less strongly. But this is very practical in the evenings, because strong blue light from the monitor is more likely to "stimulate" you.

Thank you for your answer!

I also wear glasses but I did not have such a coating on my normal glasses. I just wondered if it really works because now we all use the laptop and so much.
