Peripherals for the Visually Impaired?

schmiddy asks: "My father, a self-proclaimed Internet junkie, recently lost most of his eyesight, but he can still see a bit out of his right eye (enough to read magnified text on a monitor, with a narrow field of view). As he spends a large amount of his time surfing the web and reading, he's been finding it hard to cope. I've seen a lot of cool toys out there for the rest of us, but can the Slashdot crowd recommend any special monitors, peripherals, or (preferably (F)OSS) text to speech or other software that would help? I think he would much rather continue reading the old-fashioned way than having to use a hack like a Braille output. Also, what about the idea of simply using a large TV screen as a computer monitor?"
