Bill, Thanks for your kind words, but I don't think my understanding is so exceptional. Since becoming legally blind, I've studied what I've been able to about retinal function and retinal degeneration, so that I have a working vocabulary of the visual process and the cellular and electrochemical specifics that support it. Also, I know my visual fields and understand why gaps have appeared in my vision as they have because I've had the Goldmann Visual Fields test performed on me several times over the past ten years at the Jules Stein eye Institute here at UCLA. It's through educating myself that I've learned to understand and be better able to describe all this. Anyone could do the same, and I recommend making the effort.

I've also seen other "pictures" where views had lurred-out areas that make the whole picture almost unviewable. So I can imagine any number of variables of how people might have vision and yet not see. It certainly is a reminder to me, just as your posts are, how challenging the low-vision arena really is, how we can't take for granted what we have, and how we have to understand others' challenges that might be much greater than our own. At least you have a very good grasp of what you can and can't see. Many "sighted" people simply can't figure out what their sight problems are and/or don't pay attention to what they see let alone find ways to cope with it, so at least you are doing all you can with what you have.
