Prevent Glasses from fogging

Ok so I wear non prescription glasses with clear lens during the morning commute. Having an issue with the lens fogging so much so that I can't see well. Any tricks to keep them from fogging? Thanks

Move the lens away from your face a bit so that there is adequate air movement to prevent condensation.

Seeker333,

I've given this a try but still get some fogging. I have a strap on them so it is a bit difficult to wipe. Maybe a piece of gauze at the bridge will help keep them away. Thanks.

This stuff does work. What I do is drill four 3/32 holes into and across the top of the lenses. This allows the warm air to escape keeping the lower part of the lense clear. I use plastic goggles from Home Depot or Lowes for about 5.00. Moving the goggles down to the tip of one's nose while stopped helps as well.

Any one try these yet?

I will be getting some when the temps start to go down and the fogging goes up...

.

I wear these daily. They are vented and work great. $6.22 from Amazon.

hate to say it but go faster.

Posts about winter eyewear and fogging are perennial subjects on the Winter Cycling Forum. On the last two pages of threads on that Forum are a few, including posts by me. For example:

I totally agree that anti-fog coatings are easily defeated by heavy vapor-laden breathing, especially at really cold temperatures. Also the strategy for trying to seal the goggles from exhalations is futile [as with regular ski goggles]. For me the ventilation provided by the wide open sides of the safety glasses reliably keeps them and my eyeglasses clear and the wide windscreen of the safety glasses keeps my eyes comfortable.

See pictures below. A special innovation is that I use a vertical strip of velcro on my skull cap to attach to another strip of velcro wrapped around the nosepiece of the safety goggles. The safety glasses are then suspended over my eyes rather than resting or pressed down on my nose. Another advantage is that the safety glasses have rigid earpieces for my eyeglass mounted Take-a-Look mirror, as opposed to elastic headbands on regular ski goggles.

I've posted a lot about the fogging problem, and my solution pictured below works quite well due to the wide open ventilation of the safety glasses. I've tried various coating agents, and I think they can be defeated because cyclists are working harder than motorcyclists or downhill skiers and exhaling a greater load of moist air. Also any suggested strategy to defeat fogging should describe the conditions, since it gets worse the colder, longer and harder you ride. The extremes I encounter are single digits, very rarely below 0° F, for a 14 mile commute of about 1:15 with three "moderate" hills...

I hope I don't sound confrontational, but I think fogging is one of the most dangerous conditions I encounter during winter cycling, particularly as an eyeglass wearer, so I take it seriously. :eek:

Same concept as mine except they look much more streamlined. The holes are horizontal and are located where the lense meets the frame. Do a zoom after clicking on the glasses and you'll see what I mean. I'd get them if I didn't have 3 good pair of DIY goggles already. :p

Where does one buy Cat Crap? At a ski shop?

Probably. REI has it and Amazon.

Rain-X (for car windshields) has an anti-fog product. A bottle (~$5.00) will last a 30 y.o. the rest of his/her life. I use it on the inside of the $3.00 un-vented safety goggles I got from Home Depot. Home Depot also has safety glasses that fit over prescription glasses. They don't need venting because they don't close in around your eyes. They can still fog and the Rain-X will work. You can just about perceive some blurring after a time in the cold and wet but nothing like the total whiteout condition that you get without any kind of anti-fog on your lenses.

I use Barracuda brand defogging solution. You can get it at swim shops; I got mine along with a pair of goggles and found that it works great on all my lenses, not just my swim gogs.

I have some in my cat's litter box if you want. It has some clay in it but eh...

If you're using cheap glasses, Rain-X is ok, but it does irritate some people's eyes, and it causes the plastic to get brittle. I use Blaze Anti-Fog on anything with plastic lenses. It's specifically formulated for plastic (Rain-X is formulated for glass). Blaze doesn't last long, and has to be re-applied every couple days, but it doesn't irritate my eyes at all, and it should make the plastic brittle or haze. I use it on all my glasses for motorcycling and bicycling, and my MC helmet visors.

I have three cats.... plenty to go around! :)

keep them off your face unless you are moving, meaning, take them off at stops, and wear them a little further from your face, down your nose a bit. what you need is airflow around them. if they are too close to your face you might need a different style. I like raquetball glasses myself

good subject... weird names!

I do not wear glasses for visual correction but do take eye protection extremely seriously, so always wear protection on the road, sunny or not.

I tried a product called "spit" http://bikeforums.net/attachment.php...hmentid=271675 which I found on Amazon

Thanks for the informative, near exhaustive post from Jim - one question, have you tried that catcrap stuff mentioned by Stealthammer?

My problem with the Spit thing was you have to remove a lot to prevent the smear factor and it seems very hard to get that right (most is removed and misting recurrs), so I seldom try to use it now... Curious if catcrap is better in that respect?
