Basically acid in your breath is bad for lens.

Where in this Nikon document does it say to not breathe on the lens? This is all I see in the Support Document:

How do I clean the camera lens?
The best way to clean a lens is to use a piece of lint free lens cleaning tissue and a small amount of Lens Cleaning solution. Do not use anything containing abrasives or  solvents, only use Lens Cleaning Solution.

First we recommend taking a small blower brush to blow off or brush away loose dust or debris.

Next, place a drop or two of cleaner on the tissue (never directly onto the lens) and then wipe the lens in a circular motion, beginning in the center and working your way outward, removing any marks or smear.

If the above supplies are not available a clean, dry, soft, lint free cloth can be used to clean the lens. Just use the blower bulb, then brush, and wipe the lens in a circular spiral from the center outward.

The same method can be used to clean the viewfinder eyepiece of Nikon cameras.

Great...Aliens get acid for blood and we get acid for breath.

ETA:I don't see anything about not breathing on the lens...

Geez! History changed right before our eyes. A few days ago you could corrode your lens by breathing on it. Today, the human race has magically genetically been purified and now we can breath a sigh of relief near a lens again.

Nikon signed a deal with a breath mint company.  there will be little Nikon tins in every box.

But I am impressed that they reacted so swiftly.  Sony was directly informed several times of errors on their websites and it took weeks.

Breathing on a lens? Absolutely a no-no not even for your reading glasses, let alone a coated $2,000 lens. All this does is embed the grit into the glass. Reading this thread has reinforced my decision never to buy a used lens.
I think the guy who suggested Windex was perhaps drunk and looking for attention, so ignoring the ammonia factor here, will just say do some basic research.
Under what circumstances would anybody who cares about glass breath on it for cleaning? If your in the rain or snow - wipe the lens with your cotton t-shirt if you have to, because breathing on it won't change anything...you're at the ocean or something and there's sand and grit? No way you breath on the lens ... you have back up lenses and clean them all properly after the shoot...in a studio? Crap no ... you've got a lens cleaning kit in the studio right??
Never breath on a lens for cleaning unless you believe in cleaning the sensor in the same way!
Get a micro-fibre cloth from any camera store...geez $3.50!!! Breath on the viewing screen if you must, but you don't have to with the micro-fibre lens cleaning cloth in your bag.

lots of strong words in the post but do you  have anything to back it up?  nobody was talking about just breathing (although breathing is not optional).   you breathe on the lens before wiping with t-shirt, microfibre, LP or whatever.  of course if there were too many onions in your diet the glue in the mountings might soften and the front element could fall off

Well, all the people who bought my used lenses are SOL because I rocket blow my lenses, then breathe on them before wiping them with a clean microfiber cloth.

I will continue to do so, so if I ever try to sell any of my current L lenses, those are worthless.

I will take them off your hands for scrap if you pay me 30$/gram to haul them away and provide a certificate from AECL that your breath is not radioactive.
