Somewhere recently I recall seeing a note about a warning label on some medication that said "Do not use if your eyesight is not good enough to read all the instructions."

On a par with the elevators which have the floor numbers on the buttons in Braille for the blind, but with the control panel located where nobody is gonna find it without exceptionally fine vision.

Braille labels on the elevator buttons are almost universal in the US now, but only because the elevator manufacturers won't sell you a control panel without them. But recent reports show that very few visually handicapped persons are being taught to read Braille because of some theory that "it's not really helpful" and makes it "too difficult to blend in" with others. I think that means it makes the school administrators nervous to have them around - visibly?
