Anti-fog for glasses and masks

[math teacher]

What have you found that really works? I've heard shaving cream, baby shampoo, and I see on Amazon that there is a product for anti-fog. I have anti-reflective lenses, so that is something to consider as well.

I haven't tried it but a friend just posted about this today in FB and said the product she got from her eye doctor was awesome and safe for glasses with special coatings, etc

The optometrist recommended any specialist spray that didn't contain alcohol.  The one I have helps a bit. She warned against using household products  - they have seen damage caused.

I put my glasses over the top of the mask and find it helps. I have homemade masks that come up pretty high

I got some FogAway for my husband from Amazon. I didn't check the ingredients, but he says it works well.

I have Optix 55 and it works fairly well when applied correctly. FWIW, I've found that washing my glasses with a drop of Dawn dish detergent, rinsing and then lightly blotting dry (not wiping--you want to leave a tiny bit of soap residue) helps a lot, too.
