I have written a little before (under Simply Seeing Or Not) about Macular Degeneration.
Warning! do not watch this video if you have just been diagnosed with this condition.
If I was depressed when I got this diagnosis i would have been suicidal by the time I had watched this!
I think it is dated and patronising in the extreme (little old lady/childish rhymes/cartoonish). Profoundly negative (Gloria's life is over). Not even accurate (people with advanced AMD do not live in a black world, they still see light and have some peripheral vision). Does playing on our worst fears really make people more likely to donate? The thought of a newly diagnosed person looking for 'help' and finding this appalls me, and I am amazed that anyone could think this is appropriate or in any way constructive.
Just out of interest I looked up Cancer Research uk for comparison - what a different approach.
More on the subject when I have calmed down :-)
