All of you are so fortunate and cavalier. You have no clue as to blindness, I am forced into finding out as my 28yo grandson was run over by a Tahoe, dragged 60 feet and his brain and body bumped and beat horribly. He is recovering from brain injury and blind.
You have no clue as to how hard it is to get him help because of brain injury and blind too. There is help for brain injury but being blind throws a curve the same for being blind, brain injury handicaps you. So, no one really wants to deal with him.
It is difficult to tell money, to learn how to identify clothes, where you are, and on and on and on.
Just be thankful you can see and be so confident and cavalier.
So, who's being cavalier? It's not like many of us haven't been through periods of blindness, or loss of vision to the degree that we couldn't readily navigate curbs, count money, read a newspaper (or even the internet where we can toke up the text size), and so on.
I'm still having trouble with 3-D ~ my eyes are simply not reporting the world to me correctly, and may not ever do so.
Still, 2-D is better than nothing, or having eyes so sensitive to light that nothing can be seen.
There are, in fact, others here speaking from their own experience, or have worked with blind folks enough that they have a good understanding of what's going on.
