Face masks and glasses don’t always play well together. That's why FogBlock is here. Use this anti-fog spray to keep your glasses clear for up to 24 hours per application. The streak-free, non-toxic formula is safe to use on all types of lenses including glasses, sunglasses, and goggles. Spray FogBlock on your lenses, let it dry for 5 minutes, and enjoy clear vision all day. No wiping needed.
Whether you are running, cycling, exercising, going out in public, or an essential worker, FogBlock makes it easy to wear glasses and a mask together. The lens spray eliminates the need for face masks with nose bridge clips, so you can breathe normally without fogging up your glasses. Enjoy a crisp, clear view while you’re wearing a mask in public.
Great for use with all Zensah Face Masks!
I them at work and in the gym. Also have ordered for all my staff! Love this product!
t really works! I can now wear my glasses with a mask and they stay perfectly clear.
best antifog spray that I've tried
Very pleased with the results of this product. My glasses did not steam up at all while running.
Glasses still fogged up, just not as much.
Not good will not buy again very unsatisfying with the anti-fog fogblock does not work well at all will not buy again
I tried it and it really didn't work. My glasses still fogged up. I use Zensah mask but I have a beard, which I think blocks air from going out the bottom of the mask. So, most/all of the air goes out the top and my glasses fog up. This is the third different anti-fog product I've tried. None have worked.
After each application, I have only been able to get approximately 30 minutes of fog free sight thru my glasses!
