Anti-Fog
 

Over the years, I've tried just about every goggle there is. I found this "new" one that claims to be great but I'm unsure. http://www.gemplers.com/product/WEBG...Safety-Goggles Is there any type of goggle that wouldn't fog up?

I've had good luck with a goggle made for skiing by Bolle. I don't believe it cost more than the one you linked and mine has a much thicker foam cushion around the edge. It allows the lens to breathe and I haven't seen it fog yet. In fact, the times I have thought it was fogging, it was actually my glasses which I must(!) wear underneath it that were fogging. The headband is much wider and more comfortable looking than the one you have found. FWIW.

I don't think there are any that are 100% fool proof.

Have you tried a pair of well ventilated ski goggles with double lenses? Also, if you are wearing something over your nose and mouth like a balaclava or scarf, make sure your breath isn't getting deflected up into your goggles.

The pair of Smith goggles I got this year have worked really well. I used to have problems with fogging (icing actually) on the inside of the lenses of my old goggles when it got really cold (like -15 or colder) but these have been great.

You need venting, and keep the goggles/glasses clean. I've had good look minimizing fog formation by rubbing a dab of dish washing liquid on the surface and rubbing it into a film on both sides. Seems to works as well as anything else and is dirt cheap.

Understand you you will never get rid of the fog, only minimize it.

To prevent fogging, you need airflow to keep humid air from sitting behind and condensing on the cooler lens. All of the above mentioned elements help reduce fogging-- coatings, insulated lens, soap and other treatments-- but to prevent fogging, you need to either heat the lens as SkiDoo does with their goggles, or keep air moving as Smith does with their Turbo Fan goggles. Along the lines of the latter, Habervision make a fan module called the Eliminator that retrofits many goggles with an automatic exhaust fan.

As an eyeglass wearer riding a 14 mile one-way commute as low as 0° F, here's my discussion of the fogging problem, and my perennial post on my fogging solution.

Jim, I don't understand how your open goggles help with glasses fogging up. Can you elaborate on the difference you have experienced with closed goggles vs the open ones you show in the picture?

I used to use anti fog that was meant for Paintball. It worked amazing. I think it was fogdoc

Thanks for your reply. Boston is balmy compared to what youse got in Minnesota. See my discussion:

As a prescription eyeglass-wearer I have the added problem of eyeglass as well as goggle fogging. IMO, so called "closed" goggles have never been sealed enough to completely keep out moisture, which then might fog up the eyeglasses, so you have to stop and clean the spectacles separately. Furthermore I think even the anti-fogging agents can also be overcome by heavy, moist exhalations,

In my discussion, I wrote that cycling, especially vigorously, as when going up hill produces an unusually heavy burden of exhaled warm moist air, and we have less onrushing air passing our heads than a downhill skier or a snowmobiler, Nonetheless there is enough, but has to be produced by our own expended forward progession. Unfortunately as we ride uphill we expire more but go slower; and when going downhill we don’t breathe as hard, but have plenty of orushing, ventilating wind.

Also YMMV with terrain and temperature, so I plead with those who enthusiastically endorse their solutions to the fogging problem to describe their cycling conditions.

Finally, my safety goggles, unlike ski goggles, have those rigid earpieces to support my favored eyeglass-mounted mirror. Also with the Velco suspension, the goggles rest comfortably on my head without a compressive headband.

I use plain cycling glasses and pull them down my nose at stops. Works every time.

You could try mesh goggles. They're used a lot in forestry. By design they're really not capable of fogging. But they can be a bit breezy and don't provide as good a view as unfogged plastic lenses.

Got it, thanks. I read your discussion before replying, but I missed the part about closed goggles not being closed enough. Most of my winter rides will be on trails so little speed and lots of panting.

Under those circumstances, mesh goggles wouldn't keep my glasses from getting moisture, so I'm thinking trying to get goggles that do seal on the bottom and have big vents on top. That way the hot moist breath will rise past and not come in from under. And I cannot imagine electric fans working for long enough in 10 deg F weather.

Hmm, sounds interesting. Potentially simple, but you'll still need to deal with warm, humid air off the skin. Could be interesting, though that goggles are all about venting make me think its going to be a dead end.

They're designed for snowmobiling and skiing, have been around for years, and are USA military spec, so I don't know why you think they won't work in the subzero cold. No need to imagine; read about 'em.

Uh, ok. :o
