The Best Anti-fog Sprays for Glasses and Goggles

Fact checked by Andrew Carnegie

If you are wearing prescription eyewear or a pair of protective glasses for safety purposes in the workplace then you might have been aware of how uncomfortable and annoying having them fogged up is. Note that fog is most likely to accumulate on your glasses or goggles during heavy rains or winters.

You might experience the same in the headlights of your vehicles. In most cases, users clean the glass only to realize that the fog tends to come back and accumulate even faster. The best anti-fog spray is the ideal solution for those scenarios.

The anti-fog spray for glasses can help you overcome those situations that you can’t expect to get resolved just by changing your pair of glasses or throwing your goggles. Keep in mind that the built-up fog on your glasses can be a hurdle as this can block your vision.

If you do not treat it with an effective anti-fog solution, then you will also be putting yourself in danger. A reliable anti-fogging spray can be expected to work through its hydrophilic solution. This means it has water-attracting capabilities. Note that the fog accumulating within your goggles and glasses are small water droplets.

Once these droplets of water get exposed to a hydrophilic surface, you can expect the present moisture to unify, creating a thin layer, instead of separating it into even smaller droplets. However, take note that the hydrophilic properties are not the only ones that make the top-tier anti-fog spray for safety glasses effective.

It also works effectively because the spray is designed to stick well into the lens. If you are concerned about your vision being hampered due to the accumulated fog then it is time to check out the many choices for an anti-fog spray for prescription glasses, protective eyewear, and goggles in the market today.

Among those that are appropriate for the needs and requirements of the majority of prospective users are the following:

List of 9 Top-rated Anti-fog Spray Reviews of 2023

1. ZEISS Fog Defender System Anti-Fog Spray

Coming from the makers of some of the world’s top-notch optical systems and optoelectronics, I have high expectations from this Zeiss glasses anti-fog spray. Like most kits, this one includes a good-quality microfiber cloth.

The product description promises up to 72 hours of no fog for glasses, and I can confirm that it delivers. Even more impressive is that this solution is easy to use.

But you need to make sure that the glass is clean before spraying both sides. Rub it so that the entire surface is covered and let it sit for one minute. After that, wipe it gently. It’s quick and easy, right?

If the directions are followed correctly, I guarantee that it will work as it is supposed to. Beyond that, it will not damage your lenses’ anti-reflective coatings.

Apart from eyeglasses, it is formulated for camera lenses, binoculars, face shields, and goggles that athletes wear for sports like skiing or swimming. Thus, I recommend this for athletes, workers, and photographers.

For a small spray bottle, I’m taken aback by how expensive the kit is. Also, even though the anti-fog solution can last long, I still have to reapply it if it gets washed away by a lens cleaner. As someone who wears eyeglasses every day and is constantly being exposed to dirt, it does not last very long.
What We Like
  • Superb all-around anti-fog solution
  • Very easy and quick to use
  • Provides long-lasting coating
  • Does not damage other lens coatings
  • Comes with a microfiber cloth
What We Don’t Like

Despite its high price, this defogging solution does a great job of lifting the fog from glass surfaces. More importantly, it is safe to use on anti-reflective coatings so I don’t have to worry about damaging my lenses!

Aside from its wide coverage considering its ability to handle different items, I am sure you will love how easy and quick it is to apply it. It is formulated to produce immediate results. All it takes is to spray it just once then rub the solution and rinse it. After that, you will notice the surface receiving more protection and remaining fog-free.

I am also sure you will not regret buying this fog-off spray as it has safe and natural components. It is hypoallergenic as it does not have any harmful chemicals and ingredients. It comes out as a pure and natural water mist formula, which can be easily and safely applied on all surfaces.

It is also versatile that it is useful for polarized, transition, and prescription lenses.

However, one flaw I do not like in this anti-fog spray for sports goggles, prescription glasses, protective eyewear, or for any other surface is that you might need to reapply it frequently especially when used in extremely cold weather and environments.

It is also made in such a way that it will not harm you nor the environment. It is also long-lasting. You will even enjoy its ability to deliver over 200 sprays.

I also find the bottles containing the spray compact. With such a compact structure, carrying and storing it anywhere is easy. This anti-fog spray from Just Add Water also has the advantage of being easy and quick to apply. This ensures that you will not have a difficult time maximizing its effects.

Proudly made in the US, this solution is originally formulated for navy seals who need to see clearly amidst harsh weather. Based on experience, I can attest that the anti-fogging properties work when I need to drive during winter.

Depending on the conditions, I would say that one spray lasts a full day. Hence, I don’t have to stop what I’m doing to reapply m the solution. This helps me work more efficiently and safely, too! Because of that, I know many folks who work in different fields rely on this product.

Unfortunately, the kit does not provide any instruction. In my view, directions are crucial for users since it informs us of the best ways to use the product. I struggled to figure out how to use it, which resulted in foggy glasses. If it were not for the reviews I found online, I would have wasted an entire bottle.
What We Like
  • A small bottle goes a long way
  • Works effectively in harsh conditions
  • Includes microfiber cloth and pouch

It does not to be reapplied too frequently because it helps keep the lens defogged for a long time.

Another highlight of this product is that it also acts as a real cleaner by removing not only fog but smudges and dirt from the item where you spray it on. The fact that it is created using a unique blended formula makes it possible to work safely with a non-AR coated lens, too.

However, one fault I noticed in this spray is that the instructions in its bottle are slightly hard to read because of the small fonts used.
What We Like
  • Affordable without losing its defogging power
  • Produces long-lasting results
  • Guarantees a streak-free finish when applied
  • Boasts of a unique blended formula that is compatible with non-AR coated lenses

In such a case, it can help in keeping one hundred percent moisture or fog away from the shield, promoting ease in breathing and seeing.

However, I dislike the need to reapply it every few days because I noticed that the reapplication is quite a hassle.

  • Wide coverage considering its versatility

Another great advantage of this solution is that it makes use of natural color for its active ingredient, making it invisible upon application.

One drawback, though, is that it only seems to work on wet environments and applications.

What is an Anti-fog Spray

best anti fog for goggles

The Occupational Safety and Hazards Administration (OSHA) requires workers to wear safety glasses to protect their eyesight while they are in the work area. However, there are times when you cannot help but take them off for a couple of minutes at a time because of fog.

This usually happens when you are working in a particularly humid environment. If you want to keep your safety eyewear fog-free then you need to apply anti-fog spray on it before every use. Anti-fog sprays contain surfactant substances.

This means that when this is applied to a glass surface, it spreads a substance across the surface that lowers the surface tension of the water it comes in contact with. This allows a super thin layer of water on the lens to form, thereby preventing them from fogging up and greatly reducing your visibility.

If you work in a hazardous area then the last thing that you want to happen is to suddenly lose most of your vision because your glasses suddenly fogged up. So before you step into the site, make it a habit to spritz on a bit of anti-fog spray on your safety glasses.

Do the same for your eyeglasses if you wear a pair. This little bit of precaution can go a long way in preventing serious accidents at work.

How Does It Work

There are several ways for you to prevent the glass from fogging up. First, you can do what swanky hotels do for their bathroom mirrors. They have tiny heating elements embedded inside the glass that automatically turn on when one activates the lights.

These heating elements are the same ones used in the rear windows of cars (you must have seen those orange-brown stripes that go across the window). However, you will not find this method useful for protective eyewear.

The other way to prevent fog from building up on plastic and glass surfaces is to cover the entire surface with a hydrophilic coating. As the name suggests, hydrophilic (meaning water-loving) coating attracts and absorbs water.

This prevents fogging by absorbing the water in the air before they even get the chance to attract each other and form tiny droplets on the surface of the glass, which is the visible “fog”. Some known hydrophilic substances include hydrogels, certain polymers, polyvinyl alcohol, and colloids.

Finally, there is one method that most anti-fog sprays use and that is by applying surfactants to the surface you want to treat. How does this work? By preventing the condensed water from forming small water droplets on the treated surface.

Water molecules are more attracted to each other rather than to the glass surface, so if you weaken that attraction, there will not be any water droplets forming on the surface you treated. Surfactants get in between the water molecules to prevent them from sticking to each other.

If droplets do not form, the water will just spread evenly across the surface, creating a thin film of water that will not interfere with your vision. Several substances can also act as surfactants. The most common of them are rubbing alcohol, shampoo, and liquid dishwashing detergent.

Types of Anti-fog Sprays

best anti fog spray for glasses

There are several kinds of anti-fog products that you can use to treat your safety goggles, visors, and even your prescription glasses. However, keep in mind that there is no one product that you can expect to be better than the rest. It is all about the convenience of use, so consider which one makes you feel comfortable when buying one.

Anti-fog Spray – This is the most popular kind of anti-fog product out there and by most accounts, it is the easiest to use. You just need to spray it from a distance to ensure that there is an even film of anti-fog chemicals all over the lenses. You should then wipe off the excess using a microfiber cloth until it is completely dry and clear.

Anti-fog Balm – This product often comes in a small container and you apply it by hand. You just dab a bit on your fingers and rub it all over the lenses of your goggles or glasses. Then using a clean piece of cloth, buff the lenses until they are completely clear. You are now set for an entire fog-free day.

Anti-fog Sheet – These are like moist towelettes that come in small packs. The only difference is that they contain a surfactant solution that will clean the lenses of your safety goggles or prescription glasses.

To use this, you just need to tear open one packet and pull out the moistened fabric. Wipe it all over the lenses until they are clean. You just need to wait for the lenses to dry before you can wear your goggles and/or glasses.

Why Do You Need an Anti-fog Spray

OSHA requires that all construction personnel use proper eye protection, especially when working in an area where the possibility of getting hit by flying debris is definite. Since you cannot predict where all these dangerous debris will be coming from, it is best to protect the most fragile and exposed part of your head – your eyes.

This means you need to wear safety glasses whenever you are in the worksite. Make no mistake about it, though. Note that while wearing proper eye protection at all times is essential for safety purposes, there are also certain times when this safety gear can cause accidents.

How can something that was supposed to keep you safe and away from injury cause you harm? It happens when the lens of your safety eyewear starts to fog up and greatly decrease your sight.

This is especially terrible if you are operating any heavy machinery or working outdoors during a hot, balmy day and then suddenly your vision blurred, so much so that you could not even see your hands in front of you. Don’t worry. You haven’t gone blind. It is just your safety eyewear suddenly fogging up.

What you should be worried about is that the heavy machinery that you are supposed to drive will suddenly be barreling through the work site out of control because you suddenly panicked after noticing that you could not see anything.

Now you might think that there wouldn’t be any problem if you did not wear your safety goggles, but that is not only a clear breach of the rules and regulations of the company and OSHA. It is also unwise to put yourself at risk of serious injury just because you do not want to run the risk of losing vision.

You should not forego wearing a required piece of safety equipment just because you are afraid of your safety eyewear fogging up at any time. Instead of not wearing protective glasses, you should just treat them with a good quality anti-fog spray and you would be good to go for the rest of the day.

Buying Guide

best anti fog spray for safety glasses

The nice thing about shopping for something small like anti-fog sprays is that they do not cost too much. This means you can afford to buy a couple of different brands at a time then choose the one among them that you find works best for you.

To make your search a bit easier, here are a couple of factors that you should take into consideration when choosing the best anti-fog product:

Ease of use – The way to make people want to use a product is to make it as simple as possible. Put yourself in the shoes of your customers. Would you want to use an anti-fog product that takes several steps to apply and you have to wait a couple of minutes more to allow it dry before you can use the equipment?

Of course, you will more likely use a product that only takes a minute or so to use.

Length of effectiveness – Another positive characteristic that you would want to find in an anti-fog product is the length of its effects. Which would you rather choose – a product with effects that can last at least for an entire day of work, maybe even longer, or one that only has effects for a few minutes? Of course, you would want to use the one with longer-lasting effects.

Storage – Portability is important when it comes to anti-fog sprays and similar products. They have to fit in your pocket or your EDC bag so you can bring them anywhere. The spray bottles should be small enough that you can bring them with you on the plane if you ever need to travel.

The spray bottles should have around 6ml to 10ml capacity. Balms are usually placed in a small, circular container so they can be taken anywhere, even in your carry-on luggage at the airport.

Customer Demand – Products that have been around for many years and are still held in high regard by their customers are more likely to be more effective than their rival products. Look for products that are being used by more people. Odds are, those products are more effective than the others.

The great thing about companies that have a lot of staying power is that they do not remain stagnant. They try to improve on their products all the time, which means you will be getting a superior product from a company that has been around for a couple of decades compared to those that have only been in business for a year or so.

Price – Anti-fog sprays should not be so expensive that you can only afford to buy one bottle or container at a time. It is always better to have more than one anti-fog spray so you are unlikely to forget bringing it to work. If possible, buy a couple of bottles just to be on the safe side and leave one in your work locker.

Type of Product – Anti-fog products come in different forms and each of them has its benefits and disadvantages. Some anti-fogging sprays gain popularity because of their convenience. However, their effects do not last quite as long as most people would want them to.

This is why you need to reapply them once you notice patches of fog forming. You can also invest in anti-fog balms. The neat thing about this product is that you do not need to use that much because it will last for quite a long time.

There are even instances when it can last up to two days of use from a single application. The downside of this is that it takes a bit of time to apply, more so when you want to apply a double coating for a longer-lasting effect.

Materials Used – There are different kinds of anti-fog products that work on different kinds of materials. So when you are searching for anti-fog products, consider the materials you will be using them on.

For instance, you should not use anti-fog products that are meant for polycarbonate or plastics on your prescription eyeglasses. Using the wrong kind of solution to materials will scuff up the surface and may even cause severe damage.

What kinds of activities you will be doing – Are you going to be operating heavy machinery? Will you be playing paintball in a humid wooded area? Will you be using it for skiing or snowboarding down a snowy mountain? Depending on what activity you will be doing, you will need more or less anti-fogging protection.

For instance, if you will be operating heavy machinery during the middle of a humid summer, then it is advisable to apply an anti-fogging solution not only on your safety eyewear but also on the windshield of the cab in case the air conditioning suddenly conks out.

Care and Maintenance

If your line of work requires that you wear some kind of vision protection equipment, like safety glasses, goggles, or masks, it is a good idea to invest in a rather large supply of anti-fogging products. Some stores offer huge discounts on these items when you buy them in bulk.

However, you need to know how to store them properly so that you can use all of your stock before they go bad.


Regardless of the type of anti-fog product that you choose to stock up on, they all need to be stored somewhere cool and dry and away from direct sunlight. If you have a cabinet in a corner of your garage or workshop, then that would be a great place to store your anti-fogging products.

You can also place them in your basement shelves if you have one. Just make sure that there are no leaking pipes in there as that might cause mold to grow and contaminate your stock.

Check the Manufacturing Date

Before you buy a box or two of the products, check the manufacturing and the expiration dates (if any). Most anti-fog sprays can be stored for around 3 to 5 years if properly stowed away. However, if you will be stocking up on balms, know that they do not keep quite as long as sprays.

Most balms can be stored for around 2 years, 3 years would be the maximum. Balms usually dry up and start cracking after a year or two if you do not store them properly. Also, before you start stockpiling, calculate how long one container of the stuff lasts.

If one bottle of anti-fog spray can last you an entire month or so, then a box of ten bottles will be enough for an entire year at the least. This will help you find the ideal product that you can store indefinitely.

Frequently Asked Questions


What are the most popular anti-fog spray brands?

With the proven importance of the best anti-fog sprays in getting rid of all the accumulated fog on any surface, it no longer comes as a surprise to find several brands vying for the attention of buyers by promising to deliver the best results.

Among those who were able to fulfill their promise, causing them to earn the trust of many anti-fog spray users, are Optix 55, Just Add Water, Splaqua, Z Clear, SURF BUTTA, Cressi, Hendlex, iGK, Scott Sports, and Atlan.

How to use the anti-fog spray?

It works in two ways. Anti-fog sprays create a hydrophobic coating on the surface that does not let the moisture settle in. The surface repels the water as soon as it starts to gather. Another feature of these sprays is the hydrophilic property. This works by attracting the water.

It collects small beads of water from inside the lenses or glass and unifies them. The layer of water provides a clearer vision of the small beads. To use, you just need to spray a bit of the anti-fog solution onto the surface of the lenses that you want to treat. It is best to spray both the inside and outside surfaces.

Wipe off the excess using a microfiber cloth. This should provide you with enough protection to last the entire workday. You can also find balms and creams that work the same way.

However, the application method differs as they need to be smeared on the surface of the lens using one’s fingertips and then buffed up real good to make the lens as clear as possible.

Can I use anti-fog sprays for cameras, telescopes, windows, and swimming goggles?

Absolutely! If you look at the product description of most of the anti-fog treatment products featured here, they work on a wide range of glass surfaces. This includes your eyeglasses, safety goggles, swimming goggles, windows, camera lenses, and telescope lenses.

How can we create DIY anti-fog spray for glasses?

If you don’t have time to wait for the shipping or drop by your local store to buy an anti-fog spray, you can always improvise a defogging solution using household items.

Option #1: Create a homemade anti-fog lens spray by mixing equal parts vinegar, distilled water, and rubbing alcohol. Stir them and transfer them into an empty spray bottle.

For best results, you can lessen the surface tension on the glass item further by cleaning it with soapy water. After that, spritz the DIY defogging mixture and see if it works!

Option #2: As mentioned above, washing the glass with soap and water can reduce fog as it leaves a fog-resistant coating on the surface.

This technique was introduced by a British surgeon in 2011. It is especially effective for medical workers who need to work while wearing a mask. Reddit users suggest bar soap and dish soap!

Option #3: Did you know that raw potato can also produce a layer of starchy film that has a similar effect on less as shampoo and shaving cream with glycerin? Try using it as a goggle anti-fog spray! All you need to do is to rub it on the lens.

How to take care of and store the anti-fog spray?

If you will not be using your anti-fog spray, you can just leave it in your purse or bag so you can use it whenever you need it to. If you have several bottles of the stuff, as you bought it in bulk, you need to store the extra bottles in a cupboard that is away from direct sunlight.

If you are going to buy anti-fog products in bulk, it is highly suggested that you do not buy more than one box of the cleaning and anti-fogging wipes. These items are notorious for drying up even while inside the packaging, which is why they do not have much in terms of shelf life.

How to get the most out of anti-fog spray?

Before you apply the anti-fog spray or other kinds of products of your choice, make sure that the surface you will be applying the product on is completely clean. If you will be using a pair of safety glasses, make sure that you wipe the entire surface of the lenses (interior and exterior), with a microfiber cloth dipped in some cleaning solution.

Ensure that no fingerprints or oil streaks are on the lens before continuing. Once the lenses are dry, spray a small amount of the anti-fog solution onto the glass, rub it in using a clean piece of cloth then rinse it under some running water. Dry it again using the microfiber cloth.

This thin layer of the anti-fogging solution will serve as the base layer so that the second layer of anti-fogging will have something solid to adhere to. Spray on the second coating of the anti-fogging product onto the lenses and rub it in just as you did before. Applying the anti-fogging product this way will allow it to last up until the end of the workday.

Here are a couple of additional tips to make the most out of anti-fog solutions:

Make sure the surface is clean – If the surface is dirty, you will need to use several coatings of the anti-fog solution to give it enough protection. Give it a good head start by giving the surface you intend to treat a good wash beforehand.

Shake the container well to make the product more potent – Some of the materials suspended in the solution might have settled at the bottom. Giving it a good shake will help to reconstitute the materials and make the solution potent again.

Use the right spray for the right conditions and the right materials – Various anti-fog solutions are made for different kinds of materials, like clear acrylic, polycarbonate, and glass, so you have to research carefully.

What items can benefit from anti-fog products?

Aside from your prescription glasses and your protective eyewear for work, other items can benefit from a good anti-fog solution. For instance, if you are an avid SCUBA diver, your mask suddenly fogging up while you are underwater can be a real hassle.

You can prevent this hazardous problem from happening by applying a layer of the anti-fogging agent on your mask before you take the plunge. Skiers and snowboarders can also use anti-fogging on their goggles. They do not want their breath to fog their goggles while they are going downhill at crazy speeds.

Suddenly losing visibility while you are rocketing down the side of a mountain can scare you out. So before you carve the side of the mountain, make sure that you apply a good amount of anti-fogging on your goggles and give it a test by breathing on the lens to check if it will not fog up later.

Aside from eyewear, you can also use anti-fogging on your car. You might have an anti-fogging feature for your rear window but you do not have anything other than the A/C vents for the windshield. Also, it will take a minute or so for your A/C if it is a humid night.

Your air conditioner makes it so that the interior temperature of your car is much colder than it is outside, causing fog to form outside of your windshield. Of course, you can just use your wipers to get rid of the fog, but it will come back.

You should apply a good amount of anti-fog products on the windshield of your car when the weather starts getting a bit balmy. Also, put them on the side mirrors, as these tend to fog up during rainstorms and as an additional precaution, apply anti-rain solutions on the glass surface as well.

Just be sure that you are getting anti-fog products that are specifically made for large vehicles, as the ones used for eyewear might not be potent enough for use on windshields.

Where to buy an anti-fog spray?

The best place to buy anti-fog products is online, preferably on the website of the manufacturer itself. Hopefully, the company’s retail site allows you to purchase single pieces of their products instead of just selling cases worth of the stuff.

If you cannot find anything in the company sites, you can try ordering them online through online selling platforms. One benefit of ordering these kinds of products online is that you can quickly compare prices between online retailers then go order from the one offering the best deals.

Furthermore, with online shopping, you can browse through the numerous sites and find the ones that have the most positive reviews from customers. This way, you will not be going in blind and purchasing products without knowing the first thing about them.


Not that many people consider using anti-fogging products on their safety gear – that is until they have a close shave with an accident that could have been prevented should they have used a proper anti-fogging product. The way most anti-fogging products work is by reducing the amount of surface tension in the water.

They are forcing themselves in between the molecules of water, preventing them from forming water droplets and fog. What you will get when you use anti-fog in your glasses is just a thin film of water, so thin that you can still see clearly through them.

Just by applying a bit of the best anti-fog spray on your eyewear, you can prevent serious accidents from happening to you or the people around you.
