I have 20/200 vision in my only good eye. Without glasses I can clearly see about three feet in front of me. With a 12x magnifying bubble mounted in a pair of glasses, I can read print sizes from the printed phone book on up. I have to guess at entries in a printed phone book, or an average printed pocket dictionary, as I can't really see the individual letters clearly.
The only way you can get the experience of seeing my screenshots as I see them is to temporarily adjust your computer so you get reverse video. Look in the accessibility control panel and you should be able to reset your machine to see my screen as I see it. For the last two screenshots, my desktop is blue, not orange, in reverse video.
On a PC the cursor is a dotted outline, which is very easy to lose track of on the screen. The Macintosh cursor is a solid black arrow. In reverse video it is a solid white arrow. I can see it well enough to find it again after clicking a link and being moved to another page.
The way my vision works, contrast is everything. Black background gives more contrast to the print, then black letters on a white background. I find it interesting that for normal vision readers, reverse video is distracting and is avoided when possible.
In order to produce the square box you see around my cursor in the 2nd and 3rd screenshots I do the following in the accessibility panel. I increase the computer's screen zoom magnification to its maximum, but only request the "preview" viewing area. This produces a nice drawn rectangle around the cursor. This is what I use all the time on my computer, to quickly find the cursor when I lose track of it. With the 12x magnification in my glasses, I can only see about one square inch of screen at a time. This is why it is so easy for me to "lose" the cursor while working on my computer.
I can use Page-Down, or Down-Arrow keys to scroll. Page-down moves too much of the screen before I've gotten to the lower part of the page. So, I have to use the Down-Arrow key.
I was shocked to realize that I could read at my computer for three hours or more, with no pain anywhere in my body. I sit with my back straight in my chair, with the screen elevated to be right in front of my face. I have a table with a tray for the keyboard and I type with the keyboard completely recessed within the table. (I've never had such good posture).
One final note on ebooks. I live in a very small room, making a library of thousands of books impossible. With eBooks I literally own thousands of titles, all on my hard drive. This technology saves on paper, ink and the energy to print the book. Here are the links to the programs I've been discussing.
