Defogging sunglasses question

Toothpaste is going to scratch the lenses of your sunglasses (or your swim goggles for that matter).  They're plastic not glass. 

I haven't found a good way to make my glasses stop fogging.  I keep them a little further away from my face and helmet so that a little air gets through.  That helps.

Not sure of the brand.  $30 LBS special types, so definitely not glass, like the other ones I have.  After seeing the other poster's quote, yeah, that does make sense.  In diving, one of the scams is the sale of commercial de-fogger, as toothpaste works great.  However, the masks are tempered glass.  I was hoping to avoid paying for something not needed, but I guess it is.

I wear hard contacts and have dry eyes, so I understand the irritable part pretty well.    I use sunglasses as windshields, and the amber color really helps with clarity for some reason.  I found out polarized sunglasses SUCK for riding, as the contrast between sun and shade makes potholes invisibile.  :P

Spit.  Works great.

Spit on each lens, rub it around like you're cleaning them.  Repeat on other side of lens.  Dry off with whatever you would normally use (tech t-shirt works fine).

 LCDs are really just a pair of polarized lenses.  When polarized lenses are oriented parrallel to each other, you can see through (light passes through) them.  When they are perpendicular you can't.  When a current is applied to the LCD, it changes the direction of polarization of the light.  You can't see the computer or stopwatch because the light reflected by the display is polarized.  Exactly the kind of light that your lenses are designed to block.

 If you can't read your computer or stopwatch, try rotating it 90 degrees.

not sure if this will work for you, but it has worked great thru marathon training and my Oakelys for me.  Cat Crap.  Yep, you read it right.  You can purchase it on Zombierunners.com  .  Great stuff IMO.  I plan on using it in my goggles once I get my butt back into the pool.

JohnAgs3 - 2008-09-25 11:26 AM I wear Oakleys...and on cold days they will tend to fog here and there. I just push them away from my face a bit and get some air under there..that seems to help most days. I was going to use anti fog solution on them, but I (wisely) asked Oakley first and they said it would ruin the lens. So, if they are cheap glasses, try antifog, or some other "standard" antifog solution. If they were expensive, I would say to try to deal with it any other way. I am not sure a lot is going to help if its really crappy out. Maybe rain-x

same here (just not oakleys)  Never heard of anyone actually buying a product for this

Come to think of it, on really hot, long rides I could use a small windshield wiper to get rid of the pouring sweat......
