Anti-Fog spray for glasses

There's probably something you can buy that will last longer, but here's what I do:

Wash my glasses really well – hot soapy water, absorbent cotton towel it completely dry.

Rub a small bit of hand soap from a mostly dry bar unto each inside and each outside surface. Not much – about a 1 cm line.

Using a clean, cotton towel, work that dry soap around, rubbing pretty hard with each lens between a layer of towel on each side – much like rubbing paste wax onto wood furniture or a car.

That's it. You can't tell it's there, except the condensation is vastly reduced. Typically that would last me days around town. If you get the glasses so wet you wipe them dry, you'll lose some of the soap layer. Doing that repeatedly and it will diminish over time.

Often, cocking my head so more wind flows under the lens while I'm stopped helps.

The Fog Tech stuff is ok, but I have yet to find anything that beats Cat Crap: http://www.rei.com/product/623337/ek-ekcessories-cat-crap-anti-fog-lens-cleaner

The paste stuff last longer than the spray, but both work great!

One other tip, most people vent their jackets by unzipping at the neck, which is fine, but is also a guaranteed way to fog your glasses!!! Vent from the bottom, or better yet, strip some layers!

Yeah – contact lenses!
I switched to them for walking and skiing for all the foggy reasons.

Thanks everyone for the input!

Jim- I'll try that cat crap out. Hopefully it won't scratch my glasses like one reviewer wrote, but it was probably user error.

Roger- I try not to wear contacts when I go backpacking. Don't like to fiddle around with my lenses with dirty hands/too lazy to take proper care of them.

I suppose I could try out some of those new lenses that I can wear for an entire month at a time without removing. That would be oh so nice. Surgery in the future would be great, too.

I use cat crap too, though I haven't done any sort of comparison with other products.

Part of getting this to work is just tuning expectations; I find that even with cat crap there are conditions under which I'm still going to have at least some fogging.

Just knowing that and accepting it is part of the "glasses path". That, and sometimes just setting the glasses a little farther out on my nose until the fog clears. Or very very infrequently, taking the dang things off and just making do if the fog is so bad that I see better without them.

Is there a hole between the lenses or is it solid? It does make a difference. Solid is good for riding bikes, otherwise I go for the venting.

They're my everyday seeing stuff glasses. I've lost or broken all my previous pairs so have no backup. My last pair were transition lenses (current ones are too), with Ray Ban frames, which are now sitting at the bottom of Stuart Lake up over at the Alpine Lake Wilderness at the base of the Enchantments in Washington.

My eyes are bad enough that I can't hike on trails without glasses/lenses. Last year I didn't do too much snow/super cold backpacking, but this year we're planning on getting out much more often.

I'm going to try the cat crap stuff for now, and I'll see about getting some extended wear contact lenses.
