Title: This one works and lasts all day
Review: 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.

Title: My skepticism has melted away
Review: 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!

Title: Works Great!
Review: I bought this because I walk outside and now that it is really cold my glasses have been fogging up a lot. I asked my optometrist what he recommended because I didn’t want anything that would damage the lenses on my prescription glasses. This is very easy to use and keeps the lenses clear for my whole walk. I have gone a couple days without reapplying and it still works. My only complaint is that I wish they would sell a larger refill bottle because if you use this a lot it gets pricey.

Title: It works 10000% as described no problems
Review: 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 offWhat 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)

Title: Leaves your lenses a bit cloudy
Review: I have used different lens defoggers and I would say this isn’t on my top list. I know most leave a little residue on your lenses, but even with the cloth, my lenses looked dirty. It does help with de-fogging.

Title: It actually prevents fogging
Review: 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.

Title: Works very well when applied properly
Review: 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!

Review: 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.

Review: Funciona muy bien. Lo único malo es que el efecto dura poco. Lo uso en mis googles para nadar y funciona perfecto pero lo tengo que aplicar antes de cada uso. Sinceramente no me representa ningún problema dado el beneficio, aplicarlo ya es parte de mi rutina. En mis lentes de aumento lo aplico cada semana y en el visor de la moto cada 3 o 4 días.
