Prevent Fogging in Eye Protection

At work we occasionally have to don Kevlar suits with hoods to replace 5500W High Pressure mercury lamps in our tools. We use a gel type of anti-fog on our mask's which works great.

No idea what it's called though as it's supplied by the Dutch.

But, there is stuff out there. Like 308win said, go to an eye glass place and see what they offer.
 
I heard a hint about rubbing a cigarette on one's windshield to prevent fogging a long time ago. The explanantion that was given was that the glycerine in the cigarette paper kept a thin film of moisture on the glass so that further condensation did not form droplets.

Apparently glycerine is slightly hygroscopic (absorbs water from the air)and thus keeps the windshield slightly moist.

Pure glycerine may be obtaind from almost any drugstore as an emollient (skin softener), but I must admit that I never tried it and don't know what it might do to plastic eyewear.

(It's pretty dry here in CO, so it's not that much of a problem. My problem is sweat dripping onto the eyewear, more than condensation forming.)
 
Anti-fog cure

I use a slight coat of dish soap. Just smear a little on a piece of cloth just enough to dampen the cloth, than wipe the inside side of glasses with dampened cloth. Will look a bit blurred at first give it a couple minutes and the soap wiped on will form an even coat on glasses. Works good in cold climate.
 
In SCUBA diving, a new mask is rinsed, then the pane is rubbed thoroughly with toothpaste. Let stand 5 minutes, then rinse. Don't know if it'll work on land-based eye wear, but since it relies upon something you're likely to have on hand (at least I hope you do), it may be worth a try.

Toothpaste is an abrasive. Do not rub toothpaste on your land use eyewear.
It will cloud up the lens and give a less clear view.

Underwater that is not such an issue because water will fill the tiny scratches made by the abrasive, and it won't be so cloudy.


I use a slight coat of dish soap.
Another consideration, if you are sweating and worried about fogging up you don't really want minty toothpaste or especialy strong dish soap dried on the inside of the lens.
Just imagine how much fun your time at the range will be when a little dishsoap or toothpaste mixed with sweat runs into your eye, especialy if you have no water on hand to rinse it out.
 
+1 on the dish soap.
I used it for years when I shot a lot of trap in the summer. My forehead sweats a lot and fogs my glasses so I would smear some dish soap on the lenses and then wipe them off with a paper towel. It left enough of a coating to prevent fogging all day. I never had a problem with any getting in my eyes.

Foggy eyewear...

Never had the problem myself, but a bicycle racing coach of my acquaintance has all his racers use Rain-X on the inside and outside of the lenses of their goggles/glasses. It isn't good on some plastics, I understand, but on Rain-X'ed glass and resistant plastics, the sweat, rain, etc, just roll right off.

Bike racers sweat heavily and constantly, and on a rainy day they also get rain on the outside of their lenses, so it's a double problem for them.

Anyhow, as 308Win said, Rain-X does it.

Buy a defogger. It's popular with scuba divers. It's a gell that you just drop on the inside and outside of the lens. Rub around and wash it off. The goggles won't fog for certain hours.
 
Cat crap is good and so is another product Gorilla Snot. I don't know the trade name for GS but it lasts a long time and is as good as CatC.
 
Get a Scott's No-Fog Cloth sold at all of your local sporting goods stores for use in the winter-time to keep your ski goggles from fogging - safe for plastics!
 
used same bottle of rain-x for 10 years till it froze

On my 2nd bottle and I don't know if I'll need more than one more before I have to stop shooting. I believe you can get them in pre dampened pads but I have always kept a bottle handy in my gun box.

If you are sensitive to rain-x and some people are, a swipe on the lens with a lemon peel works
 
Polycarbonate Glasses Fogging

My regular TRI-FOCALS are made of Polycarbonate.
According to a TV channel that does "How Is's Made" Safety glasses are made from Polycarbonate. All I do is spray alcohol on each lense and clean it with "Puffs" tissues. I have no fogging problem.
 
Dirty glasses do not fog over either and a field expedient way to keep them from fogging is hold them up from the ground and stomp your foot on the dirt. Once they get a very fine( they do not have to be dirty) coating of dirt on them they will not fog.
 
CatCrap works well for me. You put 50 or 60 wigglin' and gigglin' elementary school kids on a bus in rainy, warm weather and you need something that works. I use the CatCrap on my glasses and shaving cream on the windshield of the bus. spray a little bit on and wipe it over the entire window. Then polish the window with a dry clean cloth. Do not wash it off with water.

I also wash my glasses every morning in the shower with shaving cream. This helps a lot.

What you are doing is leaving a thin, smooth film on the surface of the glass, which leaves fewer "points" for the atmospheric moisture to condense upon. Rain-X does the same thing, with a more durable film.
