User manual for smith i/o goggle lenses?
I picked up a pair of these, but my box doesn't have any sort of user manual inside (they were in a display case outside of the box, so maybe the shop lost a piece of manual inside). I have the goggles & the 2 lenses that come with it.

I was told that I can't touch the inside of the goggles since that will wear away at the anti-fogging layer. I'm trying to google & I've searched the Smith website, but basically I can't find any information on:

1) How to clean the inside if there's dust
2) How to deal with the inside if moisture does get in when up at the mountain
3) Idk? Just general information on upkeep with these things if smudging occurs on the anti-fogging layer. And how to possibly reapply an anti-fogging layer.

Also, just curious: How does one take two of their lenses up to the mountain with them? Just leave one in the car & come back for it when it gets dark / if it gets too sunny?

You aren't supposed to touch the interior of the lens the same way that you're not supposed to touch the bottom side of a CD/DVD.

Just be gentle if you ever have to wipe away any dust or smudges because the anti-fog coating is thin. If there is dust then use a microfiber cloth (like the dust bag the goggles come with) to wipe it away, or you can blow it off with your breath.

What do you mean by moisture inside? If moisture gets inside the goggles (between your face and the interior of the lens), then it is best to get some airflow going that will make the moisture evaporate. If there is too much condensation for that to work, then use a microfiber cloth to wipe it up.

If you somehow get moisture between the two plastic barriers that make up the lens then you are screwed. You will have to leave the lens somewhere for a while until that moisture can evaporate and make its way back out the porex filter (good luck... you might want to consider a replacement lens while you wait for this to happen).

There are anti-fog sprays or balms on the market (cat crap is a popular one), but in my experience, none of them work as well as the ones that are bonded to the lenses themselves. If you rub away the coating then the sprays/balms/etc will be your only option.

I keep a spare lens in my pocket and a spare set of goggles in my backpack. If lighting conditions change, then it is easier & faster to swap goggles than fiddle with changing the lenses. I only really reach for the spare lens if I have loaned out my spare goggles to a friend or happen to be riding without a backpack that day.

I contacted smith directly about cleaning the inside of a lens

breathe on the inside then very gently wipe it with a lens cloth

when I get moisture on the inside, I go to the lodge for a bit to let it clear itself up. if there's still drops after a few minutes of thawing, gently dab it up with a lens cloth
