Mainstream Technology and Low Vision: eReaders

While many people associate assistive technology with specialized devices that are expensive or hard to find, many mainstream technology devices have started supporting accessibility features and built-in assistive technology that can make specialty tools more financially and publicly accessible for all. One of my favorite examples of this is the eReader, which has revolutionized how I access printed materials and given me access to more books than I ever could find in the large print section at the library. Here are features to look for when buying an eReader for users with vision loss, as part of my ongoing Mainstream Technology and Low Vision post series.

Screen type- LCD vs eInk display

eReaders traditionally come with one of two types of displays, LCD and eInk. LCD displays are similar to the displays found on smartphones and tablet computers and are optimized for reading in indoor environments or areas with limited lighting, while eInk displays mimic the appearance of a book page and are optimized for use with other environmental lighting such as a lamp or outdoor reading. Some eInk displays may have an optional backlight feature for providing additional illumination. In general, eInk devices offer a longer battery life compared to LCD devices.

Personally, I prefer to use devices with an eInk display, because I can read on them for longer periods of time without eye strain compared to an LCD screen. I typically read novels and other books that have limited visual content on my eReader, so the paper-like black and white display works well for this type of content. If I want to read something that has a lot of visual detail, I will read it on my tablet.

Screen size

The most common screen size for eReaders is six inches, and devices that have this screen size are close in size to a traditional paperback book. Larger and smaller screen sizes are available, and users can adjust the margins of text on their device to narrow the viewing window if needed. My current eReader has a screen size of around eight inches, though there are devices that offer up to a 10 inch eInk or LCD display as well.

Font sizes and formatting options

One of the main reasons why I love my eReader so much is because I can adjust the font size of any digital book to a size can read it at, as well as adjust other formatting details. While exact features may vary from brand to brand, eReaders generally support the following customizable display options:

  • Large font sizes, typically up to size 48-pt font on eInk displays
  • Adjustable line spacing
  • Adjustable margins
  • Support for a selection of different fonts, including serif, sans serif, and OpenDyslexic fonts
  • Line justification

eReaders with a LED display also give users the option to change the page color and adjust screen brightness. These settings can be configured within the Text Options menu, which can be accessed from the reading toolbar inside any book.

Screen reader/text-to-speech support

Screen reader support and text-to-speech are generally not available for eReaders, though these features may be available within other eReading applications for Android and iOS. Some LCD devices like the Kindle Fire have text-to-speech support, but I would recommend using an iOS or Android application over an eReader for people who use screen readers or prefer to listen to content.

Ability to add EPUBs from outside sources

I download EPUB books from Bookshare, an online accessible library for people with print disabilities, so it’s critical that my eReader has the ability to let me download books from an outside source. I add books to my eReader by connecting the device to my computer via USB, and copying files using the File Explorer application. Bookshare books do not require any additional software or converting tools to be added to an eReader, provided that the user downloads books in an EPUB format.

As of 2022, Kindle eReaders now support EPUB file formats, but has not made the process very straightforward for loading them onto devices. The most reliable method I’ve used is using the “email file to Kindle device” option, which allows users to send files to their device’s unique email address and have them automatically loaded into the device library.

Additional applications

Most eInk displays do not support additional applications or internet access beyond accessing the device bookstore. LCD devices typically support additional reading applications such as Libby for libraries as well as web browsing capabilities.
