Why do goggles fog up? - Page 2

The newest ones have built in fans and even a heated lens. This combination solves the problem!



No it doesn't.  It helps.

I guess you only have to look at cars - same issue. No need for cloths and spit!!

I'm going to try these. SG1s, as you say it's and age old post but the issue remains. For example see http://www.elk-sport.com described as air con system. Really its about safety and my boy is coming out now and I want the safest possible!!

I think we should demand more from manufacturers. I mean the products are not cheap. The technology is out there - I think they are lazy. Unless we ask for it the smiths of the world won't bother. When somebody crashes with this, maybe it'll change.

First seatbelts
Then helmets
Now...time to see!!

It's not asking too much is it.

I just get so few days to enjoy the sport that really I want everything working as it should.

Disagree,

I don't want to be paying extra money for "technology" I don't need.  Some argue the same about cars.  Certain car makers don't give you the option for a lot of accessories.   Then an end consumer is wonder why the heck is my car costing so much, I don't need all these extra add-ons (plus adding weight for racer set).  This is even taken to the extreme where in certain cars like the mitsu evo MR, the manufacture has the stones to charge extra for the "privilege" of removing functions and giving you less car (weight savings, but really the same principle applies).

 

I'll take my $50 "regular" anti-fog goggles for which I read the usage instructions (don't touch, no wipe, no spit on interior lens) and body heat regulation tips, and they work fine for me.

 

 

If for whatever reason your goggles aren't working, and it's not user error, then the free market will establish the correct price for the gear you want to buy.   But i seems it is not such a huge problem that a vast number of people are needing the goggles causing more manufacturers to get into the game, and compete to lower the price.  

 

At the same time, you need to take some personal responsibility for skiing safely and not go around expecting nanny state.  Why are you skiing around when you can't see?   You can argue the same about people wearing dark lenses on a flat day.  I don't want to be forced by law into paying $100min for photochromatic goggles, or knowing bureaucracy, a law where all goggles being forced to be equipped with nanny ambient light/moisture sensor that warns "Too dark, do not use" or "fogged do not use", but not actually doing anything but add cost and avoid litigation.

Get goggles with a fan.  They work great for me when I heat up.

Hi Bears:

 

In another thread discussing the pros and cons of the Smith no-fog cloth, I stated that for me, when I overheat, my goggles are prone to fogging up.  Usually, I don't have a problem with goggles fogging up.  What are your reasons for your goggles fogging up. (I am providing the link to the other tread as follows:)

Think snow,

My goggles fog up from my warm moist breath.  If I have a neck gaitor on, it deflects my breath upwards.  If the foam on the goggles contacting the bridge of my nose doesn't make a firm seal, my warm moist breath goes up through the gap into the center of the goggles and voila - fog on the insides of the lenses.  I've had some success cutting off foam from old goggles and glueing it onto new goggles with contact cement or rubber cement, so the hole will be blocked.  This may work for some other folks if their goggles leave a gap somewhere along the bottom of their goggles.

Goggles fog up because you are too warm. Try regulating temperature better, also if your standing still or moving slowly try breathing more deliberately and trying to blow your hot breath away from your face.
