You can also just use a very, very small amount of Dawn soap, wiped on with a dry towel, and *almost* wiped away. Works in a pinch.

What happens when you wipe it with a t-shirt?

3 years ago | Likes 11 Dislikes 0

I was thinking about that, but I (an uninformed guesser) don’t know of a reason it couldn’t be behind some protective layer

3 years ago | Likes 5 Dislikes 0

The titanium oxide is the protective layer, it is harder than glass.

3 years ago | Likes 3 Dislikes 0

I assumed it would be able to wear off or otherwise deteriorate in normal use, thanks for the clarification. Idk why that didn’t occur 2 me

3 years ago | Likes 1 Dislikes 0

Titanium oxide is quite hard, harder than glass at least so it should be hard but not impossible to scratch

Glasses fog when you go from somewhere cold to somewhere warm. Which means you want to warm up the lenses quicker. IR is perfect for this.
