Regardless, no scientific studies have established that merely watching LED screens cause migraines and I'm going to go with the scientists on this one.
Again, if we are talking solely about ebooks that are text only (that's most ebooks) and reading in good light only (that's most reading) then e-ink is best. Otherwise, LED screens are better in almost every other kind of reading experience (save for the small but important minority whose migraines are possibly caused by reading from LED screens). How's that?
My exasperation has been because this theological debate has been held many times on this forum, as the most cursory search would have revealed. How many times are we going to rechew this cud?

You're doing it again with "merely" & "possibly"... nothing "merely" causes migraines, many things can trigger them either singly or in combination and there is rarely a single trigger factor but you learn which things (individually or in combination) can trigger them and you then do your best to avoid them... also, whilst there are some generally recognised commonalities in causes, there are almost as many triggers as there are sufferers so blanket statements about "merely" and "possibly" come across as plain insulting...
It's like anaphylactic shock... some people are allergic to bee stings and once the allergy reaction is triggered then another sting can require the use of an epi-pen (which you take everywhere) to stop the reaction and stop your airway swelling and closing up. It may not betriggered by every species of bee but are you going to go out of your way to get stung by an unfamiliar bee to prove it? No, you correctly avoid bees and other stinging insects because anything else is dumb. For some people, LED screens ARE a trigger factor and don't work for extensive text reading... I can read continuously for maybe half an hour on screen then my eyes start to feel gritty, my forehead tightens and I stop because in the past I've not and ended up with a full blown migraine... and for those who've never had a migraine, you may sympathise but you have no idea... it isn't pain, it's pain at a level that virtually shuts off all cognitive function, it's massive visual disturbances and can include extreme nausea and more...
I reckon that as long as people come up with "this is crap" for people having trouble with LED/LCD reading then the cud will continue to be re-chewed...
