I'm totally blind in one eye and legally blind in the other. I grew up on the ocean in Monterey, CA and now live in the Mountains of TN. Reefing keeps the ocean close to me. I can still see light, movement, and sometimes my fish VERY close up but I think it's mostly the sound of the water, the smell of the ocean and the bond with all my tank inhabitants that keeps me going.Wow, I have to say that you might be the first blind person I've talked to who enjoys the hobby! It is a very visual experience for me (and I suspect for most of us). What draws you to it?
