Many people find it easy and convenient to read on eReaders. These devices have E-Ink displays that simulate ink on paper. The screens are non-glare and cause much less strain on the eyes than a tablet, phone, or computer screen. Many companies make these devices on which you can read not only books that you purchase, but also library books, and PDFs. I personally can no longer recommend Amazon's Kindle ecosystem, as they have now made it impossible to download and save the content you have purchased; however, if you already own a Kindle, as I do, you can still use it with both library books and eBooks purchased from other places.
