The top left seems to be telling me no glasses and no false teeth; the top right is saying no shoes (but I suspect it means ones with stiletto heels, as this is for jumping on the escape slide and it would be bad if you punctured it). The bottom picture had me completely flumoxed, and it was only when I got home and enlarged this photo I took of it that I could see what it was meant to be.
It probably looked clearer before they put a red line across it.
