Having fogged up glasses is not only frustrating to deal with but can be quite dangerous especially if the glasses or goggles you are using is being used for safety purposes. If you have to take your glasses off to remove the fog, you could be putting yourself in the way of the hazards you are trying to protect your eyes from.

Luckily there are plenty of products on the market that range from sprays to pastes that can be applied directly onto the lenses on your glasses to help reduce or eliminate fog buildup on the lenses. Here are some of the best anti-fog for glasses.

Anti-Fog for Anti Reflective Lenses by Optix55


This anti-fog treatment is specially designed for those of you that have anti-reflective coatings on your glasses. Manufactured in the United States, this patented product can help keep fog off of not only your glasses but can be used on various types of goggles, snorkel masks. and even ski masks. This product is backed by a 30-day guarantee so you can see for yourself how effective the product is.

Most users have had great success with this anti-fog treatment with some even using the product on their camera lenses to help with fog during rainy and stormy weather. Another user mentioned that they used this product on the camera of their Ring doorbell that had a tendency to fog up and it worked great. Other users mentioned it worked great on their glasses and goggles for all of those winter activities. The best thing is that this product is extremely easy to use. All you need to do is ensure that the surface you want to keep fog off of is clean, use 1-2 drops, spread evenly with a soft cloth, and let air dry for 15-20 seconds and gently wipe the surface clean.

Anti-Fog Spray by Splaqua


This is currently one of the best rated anti-fog sprays available on the market today and helps eliminates fog on your glasses, goggles, or facemask. This spray also doubles as a lens cleaner and will remove dirt, smudges, oils, makeup or anything else that could be stuck to your lenses. This spray isn’t only limited to glasses but also works well on mirrors or windows to reduce fog as well.

Most users have had a good experience with this anti-fog spray however many users report that you will need to let the product completely dry (usually a couple of hours) on whatever you are trying to keep fog off of and then polish off with a microfiber cloth. Knowing that information, this could be a problem if you only have one pair of glasses to use. If you have time and ability to let the product dry on the lenses before polishing with a microfiber cloth, this spray has been reported to be successful on motorcycle helmets, swimming goggles, prescription glasses, paintball mask, and much more.

Defog It by Clarity


This anti-fog is a little bit different compared to the other ones on this list. Instead of being a spray or a paste Defog It is a concentrate used as drops and it comes included with a microfiber cloth. If you are looking for something that is dependable and could give you long-lasting fog reduction this is what you need. During controlled tests lenses that were treated with Defog It didn’t fog while being held over hot steam for 60 minutes and was able to resist fogging up when being moved between hot and cold environments for up to 100 times.

Many users of Defog It have had great success using it on face shields on helmets but some users did mention that it was best on a brand new face shield that hasn’t gotten any contaminants such as bug splatter or skin oils. Some people found it to work really well on glasses with anti-reflective/anti-glare coatings compared to other products. Defog It is so reliable of a product that it is commonly used by the military worldwide. This concentrate is perfect for safety glasses, goggles, dive masks, prescription eyeglasses, face shields and much more.

Quick Spit Anti-Fog by Just Add Water


Quick Spit anti-fog spray will work on just about anything that could fog up and works great on anything that is glass or plastic. This anti-fog spray can be used for any wet or dry applications and is a natural, biodegradable and non-toxic formula.

Some users have found success using them on eye protection that they use for gardening. Other people did find success using this spray on their swim and diving goggles however many users cautioned that you should be thoroughly rinsing the inside of the goggles when going through the application process. Some users that failed to rinse the goggles properly before using them reported burning eyes. Most users report success in reducing or eliminating fog when used according to the instructions.

The manufacturer does not recommend it for use on prescription eyewear, more than likely due to prescription eyewear’s anti-reflective coating making defoggers less effective, but users have found that it does somewhat work on prescription lenses.

Cat Crap Anti-Fog by EK EKcessories Inc.


Cat Crap has been one of the long-time anti-fog brands for many years and has a pretty good reputation for being able to keep the fog away from your glasses and much more. Cat Crap comes in a spray as well as a paste in which the company claims works equally effective, but in my personal experience they both work well but the paste lasts a bit longer compared to the spray. If you use the spray, you will need to apply it every morning, keep in mind that if you clean your lenses with a different spray later on in the day you may reduce the effectiveness of the fog reduction.

Users have found success using this product on their rifle scopes and work well on a number of different types of goggles including swimming, snow sports, and safety goggles. Others found succeeding using it for cold weather motorcycle riding to help keep fog off of their face shields.

Anti-Fog for Glasses and Goggles by Z Clear Wax


The anti-fog wax that is made by Z Clear Wax is a compact lens cleaner and anti-fog that is safe for all types of lenses. It comes in a paste form and all you need to do is rub a little bit onto your lenses until it completely dries and polish off with a microfiber or cotton cloth. The paste will need to be applied daily or if you use any other lens cleaner on your lenses the paste will have to be reapplied. This paste is designed to work on prescription lenses but keep in mind that it is a bit less effective on lenses with anti-reflective coating.

Customers have stated that you really only need to use a little bit of the product for it to be the most effective. If you happen to put too much you can use some warm water and dish soap to remove the paste and reapply. Users have had success using it with a wide variety of products including sunglasses, prescription glasses, swimming goggles, motorcycle helmets and much more.

Fog Gone by Optix 55


This anti-fog spray by Optix 55 is one of the best if you need something that you can use fast on the go or even at home. Unlike other anti-fog products on the market Fog Gone does not require you to wait for the product to dry before wiping it off. All you need to do is spray a small amount on, rub the area evenly with your fingers, and polish off with a microfiber cloth.

Reviews for Fog Gone are mostly positive with most users finding that it works great on their goggles, facemask, eyeglasses and even on the windshield of their car. Some users in Texas and South Carolina mentioned it did exceptionally well in the humid climates that they are in. There are a few users that mentioned that it didn’t work on their car or glasses but did not mention the conditions that they were in.

Scope Dope Anti-Fog by EK Ekcessories


Here is another anti-fog made by EK Ekcessories that is designed to clean your lenses as well as reduce the amount of fog that they would get in quick temperature changes.

Sea Drops Anti-Fog by Gear Aid


Sea Drops anti-fog and cleaner is another concentrate that is used as drops in which you apply to the lenses. The main difference between Sea Drops and many other anti-fog products is instead of polishing the product off with a cloth after it dries you simply just rinse the product off the lenses after you are done rubbing it onto the lenses.

Even though the product is designed for dive and snorkel mask Sea Drops works great on all glass and plastic surfaces and will work on eyeglasses, face masks, binoculars, and telescopes. Although the product states that it is not recommended for swim goggles many users have had success using them on their swim goggles. Other users have had success on motorcycle helmets and of course divers has had great success with their diving masks.

What Causes Fogging on Glasses?

Fogging can be annoying and a hazard, but what causes your glasses to fog up?

Fogging happens when the water that is in the air condenses onto the lenses of your glasses and essentially creates tons of tiny droplets of water that is stuck onto your lenses.

This happens when water vapor that is from your breath or sweat on your face cools down when it touches the cold lenses and causes the vapor to turn into a liquid form.

How to Keep Glasses From Fogging

Having your glasses get foggy on you can be one of the most frustrating things to deal with and that is especially true if you live in a humid or cold climate. But you don’t need to live in a humid or cold climate for your glasses to fog up, certain recreational activities or occupations can put you environments where there is a drastic change in temperatures can fog up your glasses as well. So how do you keep your glasses from fogging? Take a look at the tips below.

  1. Anti Fog Coatings – There are a number of manufacturers such as Opticote that created a hard coating that is applied to your lenses by the lab and it helps eliminate the moisture that would cause the fogging. This coating is applied onto the lenses before the lenses are cut to fit your specific frames and can be applied to any plastic, polycarbonate, trivex and high-index materials. Check your optical retailer for pricing and availability.
  2. Pick Your Outfit Carefully – You may not realize it but your outfit could potentially cause you to fog up your glasses, especially if you are causing air to be trapped around your glasses from turtle necks, hoodies, or scarfs. If you must use a scarf, make sure to get one that still lets some air pass through.
  3. Reposition Your Eyewear – Simply positioning your glasses slightly away from your face could create enough airflow to decrease or eliminate the amount of fog that you would typically get if you had your glasses closer to your face.
  4. Put a dab of Shaving Cream – This has always been one of those life hacks and you could apply shaving cream to any surface that fogs up and it will help reduce the fog and help you be able to see. You can use shaving cream on your bathroom mirrors, car windshields, face masks, and even your eyewear.
  5. Use a Bar of Soap – Applying bar soap onto your lenses and polishing it off will help reduce the amount of fog on your lenses and your glasses will take longer to fog.
  6. Don’t Use Them – I know you need them to see, but if you have alternate options such as contact lenses, those might be better for you to use while you are doing activities where your glasses could potentially get fogged up. Obviously, if you do not wear contacts then this isn’t an option for you.
  7. Use a Headband – Using a band for your head to help reduce the amount of sweat that eventually forms on your face during physical activity and as a result, could reduce the amount of fog that would be building up on your lenses during those intense workouts. You don’t need to be working out to be using a headband if you are in the kitchen cooking and your glasses get foggy, a headband could help here too.
  8. Use Anti Fog Products – As shown above, there are plenty of anti-fog products available on the market and these products will help your lenses reduce fog by locking the little water droplets that would cause fog from building up on your lenses.

Final Thoughts

If you have glasses and frequently encounter fog you should try to resolve it as quickly as you can, fog can obscure your vision and create a hazardous situation. That is especially true for those that are dealing with fog when you are on a motorcycle or have fog on glasses that you are wearing for safety purposes.

  1. You are right with your summition that fog can really put us into a very tight spot and expose us to various hazards and that is the more reason we need to ensure that we always keep our glasses clean. I like the antifog spray by splaqua. Firstly, I like it because it is a spray and I also like it because it can be used on many different ways rather than strictly on glasses alone. Thanks so much and I’d definitely check it out. Thanks

  2. Great post on anti-fog products for glasses. I think I might get my dad some! Personally I don’t wear glasses at all so I have never had the experience of glasses fogging up. I do see my dad having fogging problems whenever he eats though. The steam from the rice always goes up and then he can’t see, so he always takes off his glasses before eating.

      I have this issue with steamy rice as well! They definitely work for that! Thanks for stopping by, glad I could be of help.

  3. Fog can be annoying. More drastically, fog can be dangerous. I’m so glad to come across your post because I don’t see much information on anti-fog products, or anti-fog anything for that matter. I can think of times at NFL games where my sunglasses would fog. Also, I did a bit of skiing and snowboarding when I was younger and am considering getting back into it, so a product like you have here in Anti-Fog Spray by Splaqua would be most beneficial. I’ll definitely check out the product further through your link here as it will come in handy for my next football game or snowy mountain, thank you!

  4. Thanks for this great post. Had no idea that there were so many great anti-fog solutions out there. It’s so annoying to have your glasses fog up at the best of times and sometimes it can be hazardous. Especially if you’re driving or biking. I’m going to order two different ones and also try repositioning my glasses as well. Wasn’t aware that hoodies could be a contributing factor so that’s another easy change I can make to improve things. Thanks again for a really helpful post!

  5. Wow, never knew that there are anti fog products like this ones that can be used to regulate it. Its true that the climate change can cause this. I can testify ti that because my sister gets fog on her glasses very frequently. Thankfully, you have explicated how to deal with the problem under your post here. I’m going to make sure I familiarize her with this tips and also grab one of those products. Thanks!

  6. I have been wearing glasses from the last 10 years and my daughter from last 2 years. I can tell you how much annoying when seeing foggy glasses. Especially in the wintertime, we face this problem most. But it was totally unknown to me that we could use anti-fog spray. I am really glad that I have found this. Just one question,  can I use it for kids glasses as well?

    1. Huy Le ABOC, NCLEC

      Hi there Nazmun! You absolutely can use anti-fog for kids eyewear as well. Hope that answers your question, thanks for stopping by!

  7. I got fog gone by optix 55, and it’s amazing.

    Living in very humid Houston TX and I needed a product that would stop the fogging up of my glasses as soon as I walked outside. This product works really great. For the first time there is a product out there where I can transition between A/C and outside humidity. I purchased Fog Gone and it has performed liked it said. It says Fog Gone and I will tell you I do not have to wipe them for sometime. To be honest I think the stuff stays on for days in my experience.

I specifically like the tips you have added below here. I am most definitely going to try them out and see how they work for me. Thank you so much for this informative and eye opening post.
