This one works and lasts all day
As an avid hiker who frequently braves freezing temperatures, I've long struggled with my glasses fogging up, especially when wearing a ski mask. This issue not only hindered my visibility but also diminished my enjoyment of the trails. However, the ZEISS Fog Defender System has effectively put an end to this perennial problem. The application process is simple and efficient. Before setting out on a hike, I clean my glasses and apply the spray. This small preparatory step has a significant impact - my glasses remain clear throughout the day. The longevity of the anti-fog effect is particularly impressive, as it reliably lasts until the end of the day without the need for reapplication. Prior to discovering ZEISS, I experimented with several other brands, with varying degrees of success. One brand offered a temporary solution but failed by mid-afternoon. Another was completely ineffective, while a third contained harsh chemicals that irritated my eyes. The ZEISS Fog Defender, in contrast, stands out for its effectiveness and eye-friendly formula. What I appreciate most about this product is its 'set it and forget it' quality. Once applied, I no longer need to worry about my glasses fogging up, allowing me to focus fully on my hiking experience. This peace of mind, coupled with clear vision throughout the day, enhances my outdoor adventures significantly. In conclusion, the ZEISS Fog Defender System Anti-Fog Spray is a game-changer for anyone who struggles with foggy glasses in cold conditions. Its ease of use, all-day effectiveness, and gentle formula make it a superior choice over other brands I've tried. I highly recommend it to fellow hikers, skiers, or anyone facing similar challenges with glasses fogging.

Really does work with minimal streaking/smudging
There have been a lot of anti-fog products for many years. Most leave a visible film, streaking, or smudging on the lens which is the compromise I live with for anti-fog advantage. I remember back in the 70s applying a kind of wax or soap that really did work but left the lens looking like it had been in the hands of a greasy-fingered toddler. The Zeiss anti-fog solution yields a fog-resistant coating with minimal (sadly, not zero) streaking or smudging. The coating lasts well over a day; HOWEVER, there is a caveat. If you subsequently wash your lenses with lens cleaner or soap, it will wash away the anti-fog coating and you'll need to reapply it.

My skepticism has melted away
when I was first told about this product, I was very incredulous as to whether it would work. Just one more gimmick to keep glass from fogging. I have bought so many over the years as my glasses routinely fog that I’ve almost given up. I am pleased to say that this is the real deal. I have put it through its paces and found this is an effective product for goggles glasses and facemasks. I don’t know how it works but it does. It is as easy to use as any glass cleaner and provides a great value For the money. I typically use koala cleaner (available on amazon) for all my lens cleaning. On those days I don’t need fog protection, I still do. initially I’ve been told but I don’t have to use this every time I clean my glasses. For me this would be quite prohibitive as I feel like I am constantly cleaning them. However I found that I only need to use it on those occasions when I expect the glasses to fog or my glasses fogged unexpectedly. Cleaning them with this causes no glare, Distortion, or any film which causes a problem later. I wish Don had this back in 2020 when my glasses constantly fogged while wearing a mask. That’s sad I have put this to a far more difficult challenge while I have been working on a house during first in the cold and now in the summer humidity. It Works…I recommend this wholeheartedly!

Works but not for very long
This is a very small bottle plus a small cloth. It's easy to use but must be repeated at least daily if not more often. After a treatment it does prevent fogging for awhile but only for a few hours. I wear glasses and masked during COVID. With the early Spring and pollen, I am again masking because of allergies. This product is effective but not for long term daily use. I shall keep looking for a better product. Maybe there simply isn't any other.

It actually prevents fogging
The best anti-fog system. All other wipes and sprays haven't delivered adequate fog protection. This fixes the #1 problem when riding with a full-face helmet in 30-degree weather.

It works 10000% as described no problems
So most of the time you see fake reviews on stuff but this spray works perfect. no problems no foggy edges nothing. If you apply it correctly you will get 100% anti fog. I've only had it on my glasses for about 3 hours riding around on my motorcycle but it's been ZERO Fog. not slightly, not sorta. but ZERO foggyness. Before you read below this as to what i did when applying, I took a small amount of Blue Dawn platinum soap dime sized on my fingers, put some water to dilute it further than i barely had my fingers touching the glass as i rubbed the lenses to wash it and then rinsed it off What i did was I press the spray button away from glasses until 1 full spray came out so it was loaded properly, than i sprayed 2 presses on each side (4 total) then i used the cloth that came in (opposite side of the logo, not that it matters) and i simply wiped the glasses dry as if i was just cleaning them and checked it in the light to make sure there was no missed spots. and NO fog wearing my motorcycle helmet (which instantly fogs stuff lol)

Works very well when applied properly
It does a great job of preventing my glasses from fogging up while I'm wearing a mask in the office or even when working out at the gym. It is essential to clean the glasses with soap/water and dry them BEFORE applying the anti-fog spray. If this step is skipped the glasses turn into a streaky oily mess. It's in the instructions on the box but easy to miss!

Normally I use alternative days, 4 sprays per day. This time this spray bottle lasted for only 1 month. I think this seller has sent used/display bottle.
