@cpierce@SirEgg I was so befuddled as to why the makers thought “Cat Crap” was a good name, that I felt compelled to watch the videos. The second one at least explains the etymology, though I am still not convinced it was the best idea.
@cpierce@DrWorm I learned about it when I was having the issue of my lab goggles fogging up. My TA at the time told me “put that Cat Crap on it!” I then proceeded to recommend it to all my glasses wearing friends that also had the same issue as me.
@baqui63@hchavers You breathe the same way if the mask is lower on your nose. Now if you have it so low that the top of your nose isn’t covered… well that doesn’t protect anyone. The other thing that helps is have the metal strip molded as closely as possible to the shape of your face up there.
@baqui63 Yep agreed. In essence, your breath hits the top of the glasses so you can presumably still see through the center and bottom of the lenses.
@brennyn sorry, I disagree. Unless you have a professionally fitted face mask, there will always be pockets of air for hotter breath to escape and fog up glasses. Especially in colder weather where the temperature difference is more dramatic.
@baqui63@brennyn@hammi99 I have found that if the nose metal is tight enough and shaped right wherever air escapes is not fogging my glasses. I also once had some masks with a foam strip across the top. That stopped the fogging too.
I make my masks with this wire and pull it up high too. The only time my glasses fog is if I’m out in the cold for a while then go inside.
If I have to wear the mask for a while I use that little cage thing under it now so I don’t feel like I’m smothering or eating fabric.
Another suggestion is to stop breathing once you put on the mask. Once you regain consciousness, you don’t mind the fog issue. If you don’t regain consciousness, the fog issue is no more.
In all seriousness, wear a well fitting mask. Not too loose, not too tight. Ear loops aren’t the best solution if you want to keep the max from shifting around. Even though I made a hilarious joke, the fog issue is a serious one as fog indicates air flow which the wearing a mask is suppose to help minimize.
As others said, a good fit around the nose is crucial for minimizing the foggy glasses issue. I find that when I double-mask (as has been the expert recommendation recently), I get less fogging because of the tighter fit.
I took a couple of old t shirts, double layered them with tightly woven 100% cotton, made a nose guard with pipe cleaner, and sewed a few. The trick is to use a band that goes all the way around your head, (old hair elastic), and not just your ears. This makes the nose guard sit snuggly, and also doesn’t hurt my ears. I live in the country, and work from home, so I wear them maybe once a week to go to my local Iga.
My circumstances allow a simple solution: When I’m wearing my glasses, I don’t wear a mask (at home, reading or computering). When I’m wearing a mask, I don’t wear my glasses (rare trips out and about in public).
