Fog free two hours. Rinse. Repeat.
Great product. Works great the anti-fog effect lasts about 2 hours after wiping lenses. After it only takes one wipe. At first you’ll need to fog the maybe 4 times before fog stops. Glad I bought two! Definitely make sure your lenses are clean before using. You don’t want to wipe debris that could scratch lenses. I wear a mask for work especially in the cold weather. No fog for at least 2 hours each time.

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.

Best anti fog I’ve used for sunglasses.
Works great and is reusable. No more dealing with additional sprays or disposable wipes.

Fog buster
Works amazingly! I got for my motorcycle helmet but used on my glasses first after 2 wipes my glasses were fog free. Im hoping the same goes with my helmet shield. Highly recommend even if it's just for your glasses.

I T W O R K S !
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.

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 months This 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 week 10/10 would buy again

Funziona veramente bene. Dopo un anno con gli occhiali appannati riesco a vedere. Bravi.
