Eyeglass mask

Combine eyeglass frame with a modern nasal mask
  [vote for,

So, in countries where air is polluted, people traditionally use the full face masks, which (though good for anonymity) are inconvenient:

- do not attach tightly
- they get wet from breathing

An elegant solution -- nasal masks (like the "Nasal-Aire II" - link), and a filter on the back of the clothes, or in the backpack.

However, it leaves the tubes obviously visible on the cheeks. So, a version of it -- eyeglasses that have the breathing tubes inside their frames.

       Those side-pieces are going to be pretty big. A BA hose is about 40mm i.d., and the main objective is to keep the flow resistance as low as practicable.   

       Small tubes mean higher pressures and velocities,therefore higher losses.

       Only gets a bun if they come with big eyebrows and moustache a la Groucho Marx.   

       S'pose you could do fake noseless one for the Voldemort look.

       [+] but with Groucho glasses, a nasal exhale can flutter the eyebrows, suggestively.

       This idea can be workable if the filtered air is supplied at positive pressure via a demand-valve regulator.   

       That means the filter unit in the backpack is going to need a blower motor and a battery, but such things already exist for industrial use, in welding helmets and dust masks.   

       This would also be of considerable benefit to hayfever sufferes. If the "glasses" are more like goggles, they will keep pollen-bearing air away from the eyes, and the wearer can breathe filtered air.

       Predictable Japanese anti-hayfever headwear wot I found in Akihabara, see link to photo. Most inconspicuous. Hardly a patch on the "Survive Toilet Panic" bag the council gave me when I registered at city hall. Happier days.

       You can't just leave it at that - explain.
