OK here is a quantum shift possibility. Too expensive? This is the kindle version.

Well, I have been buying and reading lots of kindle books posted here. Just so handy is the kindle system if you need to have a word explained.Just highlight the word and find an explanation come up. Words can be made bigger or smaller/ ( Are those low wattage lamps ruining your eyesight too?) Here we are, a Kindle can have letters of various sizes( just push your fingers apart and the letters increase). I am not sure that is needed when reading on a laptop though.I do not think that letter size can be changed on a PC. Seems easy enough reading on this, a PC as I read things on now.
