Turning a blind eye

Have a look at these PSAs from the agency Try in Norway:

Hilarious, aren't they? Yet for me, they bring to mind an issue that always come up when dealing with this kind of campaign: is humour the best way to normalize diversity?

I know that people accuse me of taking some ads too seriously, but in this case I'd like to think it is a smart move to get people talking. And the Norwegian Association of the Blind and Partly Sighted obviously agreed. But at the same time I know that these will rub some people the wrong way. (And others will complai that a real blind person would know exactly what was going on - which to me adds another layer of humour, actually.)

The question is, will those people be sighted people?
