Hello everyone. I am interested in an Eink ereader. I have my iPad and iPhone and they do what they do. I want to just read without distractions. I am nit sure what I am looking for nor which ebook formats I need to support. It would be nice to not be locked in to an ecosystem or format, but I am open to ideas. My wife has a Kindle Paperwhite and Kindle Unlimited. I would prefer a larger screen so I can enlarge the font. I am near sighted and need larger font. I want a lighted display in Eink. Yes I can read from the iPad but it can be fatiguing. Where should I start? Feel free to ask questions to help me find the right item.

Update: I have purchased the Kindle Oasis.
