How to prevent binoculars from fogging up – Expert Binoculars
Binoculars often fog up when there are temperature differences from inside to outside, such as when you take your binoculars outside in temperatures similar to cold (e.g. from 25°C to 0°C). This is a common problem that eyeglass wearers may have to deal with.
How to prevent binoculars from fogging up? There are several ways to do this. First, expose your binoculars to minor temperature differences to avoid fogging, in this case wiping the outer lenses with a cloth or applying a special gel or product to the lenses that allows your binoculars to reduce fog condensation.
But considering how binoculars fog up, there are two types of fogging or condensation that can occur on binoculars when you expose them to different temperatures: outer fogging or inner fogging.
In this topic, I would like to explore with you different types of binocular fogging, how to prevent it and if there is a way to minimize or completely avoid condensation in binoculars. I would recommend you read on.
This will prevent the binoculars from fogging up
The windshield of your car, your glasses if you wear them, your camera lenses, your binoculars or even your window at home, when all of these are exposed to large temperature differences, the glass will become blurred or, as the saying goes, fogged up.
Condensation is a natural process and the more moisture there is in the air, the more likely it is that binoculars or other glass items will fog up.
There are a few ways to avoid this. If possible, the first option is to put the binoculars through a slow cooling or heating process with smaller temperature differences. This isn’t very practical as there aren’t many ways to do this and even though you do, remember that the body temperature of the binoculars will make the change a bit more pronounced due to the density or material the binoculars are made of puts under pressure.
Special anti-fog lenses may be available on the market that contain a special layer that reduces fogging of the binoculars.
But besides that, we all tend to wipe the blurry lenses and keep using the binoculars. Is that good or bad?
Wipe off the condensation when this happens
It’s okay to do that. Just remember that the fogged glass is actually water and wiping the binoculars quickly will not clean them, so some dirt may be present on the binoculars glass and spread to the surface.
The first thing I would recommend when wiping down the fogged up binoculars is not to give a quick wipe, but to clean the glass properly as you would with dirt – this keeps the binocular glass clean.
As a rule, the binoculars then no longer fog up due to the moisture present on the glass surface, but this is not always the case. If this occurs again, repeat the process.
Applying special gels or products to binocular lenses to prevent fogging
Anti-fog treatment is widely available on the market, but be careful what you buy – although anti-fog treatment can drastically reduce the level of fogging on the outer lenses of your binoculars, this typically does not last very long and will not affect internal condensation (wherever this is the case).
Another thing to keep in mind is the product you are using – as big as the internet is, some of the products can do more harm than good to the binoculars glass and this can void the warranty. First, find out if you plan to buy an anti-fog treatment for your binoculars.
The above does not have to be a specific product “your binoculars the perfect anti-fog treatment”) are generally the same products that can be applied to eyeglass lenses or other items to prevent fogging.
The outer condensation on the binoculars
This is the most common form of fogging or condensation on binoculars – when the eyepiece lens or eyepiece is fogged up or fogged up from the outside and the binoculars are not damaged.
Following the advice above is the best way to ensure your binoculars stay fog free and provide the best quality observation.
The condensation that occurs inside the binoculars
This is the worst part when some of the binoculars start to form condensation inside. In this case there isn’t much you can do other than wait for the binoculars to clear.
Be careful and I advise you to be very careful if the binoculars fog up on the inside, because the performance of the binoculars deteriorates over time, as mold or fungi can grow inside the binoculars as long as the main elements for this to happen: warm ones temperature, humidity and oxygen.
In fact, the best way to avoid this is to have binoculars that are waterproof, weatherproof, and anti-fog. Shortly? Nitrogen filled binoculars.
Purging the binoculars with nitrogen removes all moisture from inside the binoculars when assembled, nitrogen dry gas is purged inside, and the binoculars are sealed with an O-ring rubber. The binoculars NO longer fog up on the inside, which drastically improves the quality of the binoculars and their longevity.
The advantages of nitrogen binoculars. I have binoculars, Nikon 7S 10×42, which I always have in the car wherever I go. In cold weather, the temperature of the binoculars is the same as the outside temperature (since the car is parked in a garage). When I drive and warm up the car, the binoculars fog up. This is not good practice unless the binoculars are defogged or purged with nitrogen, as fogging can occur inside the binoculars, but this is not the case with my Nikon model, so after a thousand or more times where the condensation has occurred, the quality of the binoculars remains the same – I wanted to point out that if the binoculars weren’t fog-free and nitrogen gas purged there would be a long time since I would have to change binoculars as damage can already occur.
If you want you can read our other article Why are binoculars filled with nitrogen gas? for more informations.
Conclusion on how to prevent binoculars from fogging up.
Condensation/fogging/fogging of the binocular lens, either on the outside or the inside, is a common fact that can be avoided in certain situations, while it cannot be avoided in some other situations.
This is nothing to worry about, but beware of storing the binoculars for a long period of time, especially in places with large temperature differences between day and night or high humidity. I would recommend you to store them in a vacuum bag to avoid the above problems as much as possible.
If condensation frequently occurs on the inside of the binoculars, water droplets may form, drip onto the inner glass, or fungus/mold may develop, which may degrade the quality of the binoculars. If you think any of this has happened I would advise sending the binoculars to a specialty shop for a full cleaning.
In the situation where you don’t already have binoculars and want to buy something, I strongly recommend you look for something that is “nitrogen purged” to avoid any problems of condensation inside.
Did you know that condensation can also form on the armored body of the binoculars and that the rubber (if it is armored with rubber) can degrade over time?
Thank you for reading this post to the end and I hope you keep your binoculars safe. Now it’s time to say goodbye and watch out!
How To Keep Binoculars From Fogging Up
Anyone who uses binoculars knows the problem. If you are outside for a long time and hold the cold binoculars in front of your eyes, moisture can condense on the cold lenses. The binoculars are fogged up. As long as the condensation is only on the outside of the lens, the problem can be solved very easily by simply wiping the moisture off the lens surface.
It’s a much bigger problem when the inside of the binoculars fogs up. Because if the inside of the lenses fogs up, it can take a long time before the condensation disappears again, until then the binoculars are usually of little use.
Why do binoculars fog up?
The fog or fog on the lenses is nothing more than condensed water vapor. This happens when an optical device (or any other object) is subjected to rapid temperature extremes, more specifically from cold to warm.
Humidity condenses on the lenses and body, forming a thin layer of water droplets.
This happens in possible scenarios:
When the binoculars are moved from a cold place (outside) to a warmer place (inside).
You take a pair of cold binoculars and hold them in front of your eyes, and breath or moisture from your eyes/skin condenses as a fine mist on the lenses
It’s annoying when this happens on the outside of the binoculars, but at least you can wipe it off. It’s a big problem when this happens on the inside of the lenses. Because moisture must have penetrated the binoculars if condensation has formed on the inside of the lenses and/or the chassis.
You need to dry the binoculars because as long as there is moisture inside, every time you take the binoculars outside and they cool down to a lower outside temperature, a fine film of water will condense on the lenses.
So you can’t see very well through binoculars and over time glass fungus grows, which isn’t good for the optics at all.
How to prevent condensation in binoculars
The easiest way to prevent binoculars from fogging up is to make sure when you buy binoculars that they are waterproof and O-ring sealed. A rating of IPX-7 or similar is best.
Such special binoculars, called fog-free, are sealed with O-rings and are often used filled with inert gas, argon or nitrogen. With these rugged, all-weather or even submersible models, there is guaranteed to be no more internal fogging.
However, fog-proof does not mean that the binoculars cannot fog up from the outside. To prevent this, there are water-repellent substances or hydrophobic coatings (rain protection, lotus effect, etc.) so that no more water droplets form and stick to the glass surface.
If you have regular non-O-ring sealed binoculars, the following tips will help prevent fogging
Only use the binoculars in good, dry weather
This can be difficult, binoculars are designed to be used outdoors and weather changes happen.
Avoid temperature differences
Unless there is a large temperature difference, moisture will not condense on the binoculars. This can be achieved by bringing it to the same temperature as the area where it is to be used.
Tip: If you are outside and the temperatures are quite cold, it is advisable to carry the binoculars close to your body, maybe even in an inside pocket. This makes the binoculars slightly warmer than the surroundings and moisture cannot condense on the lenses as easily.
Apply an anti-fog agent when cleaning the lenses
There are many products that are designed to prevent the windscreen from fogging up. There are wipes, drops, sprays and more, ask an optician or search online.
It may sound strange, but human spit can also help prevent fogging (diving trick). There is something in human spit that reduces fogging of glass surfaces when rubbed with spit.
Store dry
When the binoculars are not in use, they should be stored properly and safely. A desiccant is ideal for good storage and should be kept in an airtight box with the binoculars. The desiccant absorbs the excess moisture in the binoculars. This eliminates the cause of the binoculars fogging up and prevents fungal infestation.
Advantages of fog-free binoculars
The benefits of a fog-free – O-ring sealed binoculars far outweigh regular binoculars. The seal not only protects against penetrating moisture, fogging of the glasses or worse, promotes the formation of mold, but also against the smallest dust and dirt particles.
Actually, one has to ask oneself why not all binoculars nowadays are completely environmentally sealed against moisture and dirt. It can hardly be due to the costs, since a good O-ring seal only costs a few cents in the manufacturing process.

Are waterproof binoculars fog-free?
Why do binoculars fog up?
Anti-fog binoculars have been de-oxygenated and replaced with a dry gas such as nitrogen or argon. The binoculars are sealed dust and water-tight at all entry points. As a result, they do not fog up on the inside, are waterproof and last longer than alternatives.
Almost all of us have dealt with binoculars that have fogged up on the outside. Hopefully very few of us have experienced fogged up binoculars inside.
To learn the differences between internal and external fogging and what to do about it, wipe away the fogging and get some clarity in this guide.
Some fog-free binocular recommendations are also given.
Why do binoculars fog up?
External fogging of binoculars
External fogging occurs on the outer lens components of binoculars, i. H. eyepieces and objective lenses. This happens when it is exposed to rapid changes in temperature and/or humidity.
To fix this problem, simple methods can be used that should not cause any harm in the long term.
Inner fitting in the binoculars
The inner fog is problematic because moisture has penetrated the binoculars.
Removing internal condensation is far from easy and as such it is recommended that you purchase anti-fog binoculars as a preventive investment. Fogproof binoculars have an inert gas to prevent internal fogging and mold growth.
4 ways to keep your binoculars from fogging up (outside!)
1. Let the glass adapt to the outdoor climate
Let the glass adapt itself to the temperature and humidity conditions. Council advocates binocular exposure to pre-use conditions. For example, leave it in the truck overnight for the morning scout, or allow it to acclimate for at least 15 minutes before use.
While this method can work, it’s not the most practical solution. Blowing out the heat on the way to the tree stand, holding the binoculars close to your eyes, or putting the binoculars in your jacket pocket will fog up.
Tip:
The best way to use this method for effective results is to combine it with the following practices detailed in the next method.
2. Change some handling techniques
Pull back the eyecups and keep the eyepieces farther from your eyes to prevent fogging
Overall, adjusting some binocular handling practices in cold conditions can help prevent external fogging of the eyepieces. Various user techniques can be used to prevent the binoculars from fogging up.
In many cases, binoculars have adapted to the conditions, but body heat and warm breath will cause fogging. One trick is to pull the upper lip over the lower lip and force the breath down.
If necessary, use a tripod to keep the binoculars away from your body heat
Wearing masks or hats, especially those that cover the nose, can push heat up toward the binoculars. Keep in mind that it’s best to remove them until conditions warm, or adjust your face gear to push air down rather than up toward the eyepieces.
If you don’t wear glasses, use binoculars as if you would. Pull the eyecups all the way down for maximum eye relief. This keeps your eyes farther from the eyepieces to keep them from fogging up.
Tip:
A tripod can help keep the image steady when using binoculars with the eyecups retracted without glasses.
3. Use a microfiber cloth
A microfiber cloth is the recommended cloth for cleaning and maintaining the binoculars. It’s usually a standard accessory that comes in the box with new binoculars. Keep this cloth with your gear when wiping away condensation is unavoidable.
Why isn’t simply wiping the eyepieces the most effective solution?
Condensation is just water and the goal you want to achieve by wiping with a cloth is drying the eyepieces. If dust and dirt particles are left unnoticed on the glass, this can damage coatings or scratch the glass. If there are oils or solid substances that liquify when wet (like mud), there will be more contamination on the glass that was unintentional.
However, we are all guilty of using this quick method even though it fogs up again minutes later. If it’s going to happen, let it pass with a microfiber cloth.
Tip:
Not all microfibers are created equal. Shop carefully to protect your glass and the longevity of your binoculars.
4. Use an anti-fog agent
Anti-fog agents developed by optometrists for eyeglass lenses are generally safe for binoculars. Instead of spraying directly on the eyepieces, apply to the microfiber cloth first and then to the binoculars. This is a preventive method that also protects the glass.
Tip:
Before applying any anti-fog product, whether it is a spray or wipes, clean the lenses. Use a lens cleaning pen to safely remove dust and particles before applying an anti-fog solution to the glass.
3 Ways To Prevent And Treat Internal Fogging!
1. Buy fog-free binoculars
To prevent the binoculars from fogging up on the inside, buy anti-fog binoculars. Fog-free binoculars are always waterproof, but waterproof binoculars are not always fog-free. In fog-free binoculars, oxygen is replaced with a dry gas. They are essentially hermetically sealed to prevent internal fogging.
Even if the binoculars are used in ideal weather, humidity, dust and dirt can get into the binoculars. This can lead to the formation of mold and fungus, as well as rust and glass damage.
Tip:
It’s always better to practice and invest in prevention than to deal with internal fog.
Case in point: These photos show an extreme case of both external and internal “fogging” when I froze the binoculars to check their structural integrity. I put water in the eyepieces. These binoculars are neither waterproof nor fogproof. Water traveled through the binocular tubes to settle in the objective lens caps. The interior was compromised (where the prisms are located) and is difficult to dry, promoting an environment for mold and fungus.
2. Use a desiccant
Use a suitable desiccant to dry the binoculars if water gets inside the binoculars. Internal moisture would be evidenced by fogging or the obvious presence of water on the inside of the lens. It doesn’t wipe away when the external lenses have dried.
Place the binoculars in a zip lock bag to dry with the desiccant of your choice, e.g. B. uncooked rice, and leave it for as long as necessary to absorb moisture.
Tip:
Silica gel packets are great as they don’t allow small particles to get into the binoculars or under the armor if the build quality is compromised.
3. Store in a dry place
Storing binoculars in a dry place at room temperature is a convenient and effective way to prevent internal fogging. Dry and clean the binoculars before storing them and keep the lens caps on to protect the glass from dust.
Binoculars that are not anti-fog are prone to internal fogging. If you keep the binoculars in a vehicle or outdoors for a long time, they will be exposed to changes in temperature and humidity. The type of harm that occurs as a result of these Terms occurs even if you are not aware of it.
Tip:
Store the binoculars in a dry place when not in use – even if you are in the wild camp. Dry off the armor/exterior before storing.
Best fog-free binoculars
Are fog-free binoculars worth the money?
Anti-fog binoculars are always worth the money. There’s moisture in the air, dust particles that aren’t visible to your eyes, and the binoculars are exposed to dirt and grime during use. All of these things can affect the integrity of your binoculars and therefore your glasing experience.
While there is debate as to whether argon is better than nitrogen or whether dry gas mixtures are best, fog-free binoculars are always better than binoculars without.
Nowadays you can find fog-free binoculars in every price range. Affordability and user ignorance are no longer an excuse.
