I've got the ez reader and find that ambient light is good enough most of the time.
I also have astigmatisim, so when I read wihout glasses Iincrease the font size and its all good.
I used to use a PDA, and found myself getting sleepy in 1/2 an hour, though I usually plowed on for hours at a time. I don't get this with an EInk screen.
You may simply need reading glasses to correct the issue...Happens with age and long term use of Computer screens...what can ya do?
