The goal isn’t for the wearer to detect cigarette smoke—they can already smell it—but to:
* Alert others that there’s secondhand smoke in the area.
* Show smokers how far their smoke travels, making the invisible visible.
What do you think of this idea?
They will smell it in a moment too. They might even be able to smell it before they see the glasses.

They don’t care about this, especially in a place where smoking is allowed. And if it isn’t allowed then the solution is to kick them out, and therefore there will be no more smoke soon and the glasses won’t be doing much.
