I got the Dell XPS 15 9500. It had no PWM on notebook check and wasn't glossy so it's easier on the eyes.
So far it's been excellent and the easiest thing I've found on my eyes. I've tried everything from gaming laptops, business laptops, to even art laptops and this has been the best I've found since I started having the bad headaches over 2 years ago. I will note that my eyes "feel" it (something I'm sure eye sensitive people understand) but it has not caused me a headache at all just from using it. I definitely notice when I'm using it though.
On top of that it's an excellent laptop. Great battery, amazing speakers (the best I've ever had), the brightest screen I've ever had, I can keep mine on the lowest all day which helps battery life and it has no PWM which is great. It is even good for gaming.
This is an all around wonderful laptop and I highly recommend it for those having eye strain issues. Get it from Dell directly for the best deal as they threw in a bunch of things for me plus free expedited shipping.
Good luck guys!
Also earlier this month they had a summit earlier this month on October 15th. Dell, HP, Lenovo, and Acer with others are releasing more eyesafe products which is great! People are listening little by little (Covid has had more eye strain as well as people are indoors more). Keep your heads up guys it is getting better.
