Works great
I use this to keep my surgical glasses from fogging up when I’m not able to touch my face for a few hours at a time (surgical nurse). Never had a problem!

F I N A L L Y …a glasses cloth that really works!I was tired of the smears, even with a cotton cloth…any cloth for that matter.This truly works great! I love the thickness of it, and you can feel the quality. Hands down, or up, it’s the best so far.

Somewhat works
Followed the directions and noticed improvement immediately. Then I went from air conditioning to muggy Missouri air and no improvement. But it does get the lenses really clean.

I can see easier with the fogblock
It was recommended by a colleague of mine but was awesome to use right off the bat. I felt comfortable using them and it made fogging lenses non-existent.

Works for loupes
Am I suppose to use these on 10k Surgical loupes?I don’t know but it works and I never have to worry about my lenses fogging because of my face mask or heat or a bunch of other stuff.I use it about once a week for my glasses/loupes and i haven’t had foggy glasses for going on 6 monthsThis cloth last a long time and I follow the instruction it comes with to a T other then using it like every 2-3 days instead once a week10/10 would buy again

Didn't work so well for me.
I've tried all the internet hacks for wearing masks with glasses and none of them have worked for me. The most success I've had involves wearing paper/disposable masks and taping it around my nose and cheeks. It's not perfect, but when done correctly, I get little to no fogging. I tired this and it does not completely keep my lenses fog free. Only the center of the lenses don't fog. The surrounding portion fogs. This product also seem to "enhance" any scratches you may have on your lenses. This means any scratches that you normally wouldn't see become more noticeable after the substance is rubbed on.

Love these - they keep my glasses fog-free after walking a few miles outside then going into the store.
