How to avoid blindness

If you are a smoker, you should quit. Do it because of your children, lungs or whatever... or do it to avoid blindness!
In this ad, they made use of the bins in the streets as if they were eyes. To extinguish the cigarette, you had to rub it in the iris of the eye. The aim was like are you already blind? claiming that you couldn´t even get right when throwing it to the bin (well, yes, you had to rub it in the iris before throwing it away but it is kind of cool how they are saying that you are becoming blind...) Do you get it?

I am sorry I don´t know any more details about this campaign.
