Bortas1,
The aging vision loss, has given me tons more admiration for those like you, my wife and son who have had life long impairment. The first clue that I got was when I picked my wife up from a new work location. I saw her standing on the steps and waved,

tooted the horn and whistled to get her attention. Trying to get a parking space in Century City (Los Angeles) at rush hour is an ordeal, and I thought I had it licked. Instead she looked as if she looked right through me and ignored all my

attempts at getting her attention. Luckily, a spot opened up ahead of me and I was able to slip in with time left on the meter and walk to her location.
When I asked didn't she at least hear someone trying to get her attention, her reply startled me a bit. She told me that she heard the commotion that I was making, but all she could make out was a shape that appeared to be waving their arms. In short, she made it clear to me that for her, that could have been anyone at all, and she wasn't about to make that mistake. It kind of make sense now why she hooked up with me in the first place. I could look like George Clooney to her and never knew it.
I know that sight is a precious gift, as when I was a child, I somewhat witnessed my great uncle, who lived with us shortly, go blind. It really brought it home one night when I came home after dark and I could barely make my way to the lamp, while my uncle was comfortably navigating my home that I had known all my life but even in his brief stay there, clearly had a better idea of the layout.
