There are three versions of the Fire HD currently available: the Fire HD 7, the Fire HD 8 and the Fire HD 10. The Fire HD 10 is the best option for partially sighted users: it has the best display and fastest processor and offers more storage.
Even though it is better in comparison to the other tablets, it still has limitations. The front facing camera is not very good for video conferencing, and its battery lasts two hours’ less than that of the Fire HD 8.
All three Fire tablets are restricted to accessing the Amazon app store, though there are ways to access Google’s Play Store which offers far more accessible apps for blind and partially sighted users.
