Hello, i was a very happy owner of a Kindle keyboard and now am heart broken as the screen died exactly 6 days ago

It has been discontinued and Amazon proposes to replace it with a newer device.
My biggest concern is that the new PW and Voyage have lighted screen.
I really hate reading on my smartphone or tablet as i suffer from migranes, and that was one of the reasons i was crazy about my kindle keyboard, no back light

.
Some people say that they love the lighted screen, i am not so sure and as i live in Crete, i dont have the oportunity to check the devices myself.
Any suggestions on the eye strain and the lighted screens?
Thank in advance
