Thank you for taking the time to share your advice. I am using a Lenovo ThinkPad T450s, with matte screen and have activated Windows Night Lite function. But still migraines. I have tried the blue light blocking glasses, but like all types of glasses, they actually add to my headaches. I will try blue light screen filter -- is there a particular one to look for? What do you mean, "Lenovo has one laptop model with such display on the back, but not main screen"?
I use laptop mostly for reading and writing, so if can't watch video, etc., on e-ink screen and the screen helps with migraines, it would still be beneficial for me.
