We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
How about a Kindle or Ipad? I have vision problems as well but can enlarge the font on my Kindle enough that I can read. I also use reading glasses with built in LEDs on each side. Not like it used to be but better than not reading at all,
As FRP mentioned, take a look at the Kindle--they have a REALLY big one that will be lighter than the large Kindle Fire or 10" Android/iPad device, uses less battery and is flat out better for reading.
We're a pretty technical household, we've got 2 "regular" kindles, a Kindle Fire HD 7", and a Android tablet in addition to a half dozen laptop and desktop machines (Mac, Linux and Windows), so I've read on LOTS of computers, and the kindle is, so far, the best reading device. However the size of the 7" screens makes it cumbersome to read at larger font sizes. The larger unit might work for that.

We got my grandmother a unit like that (pre-flatscreen). She was diagnosed with macular degeneration, and was getting progressively deteriorating tunnel vision. This unit allowed her to read books, read and pay her bills, write letters, etc. It was a blessing. When she passed, we donated the unit to the local association for the blind.
