Sunglasses won’t do much good if they’re constantly getting fogged up and preventing you from actually seeing what’s ahead. Luckily, there are several measures you can take to help keep your sunglasses fog free.

To maintain clear, fog-free sunglasses, be sure to wash them regularly with soap and warm water. Doing so will remove skin oils and other substances that tend to accumulate over time. You can also apply a protective layer using shaving cream, anti-fogging spray, or permanent hydrophobic coating.

As you can see, there’s no need to struggle with foggy sunglasses on a daily basis. A few easy tricks will help you keep the fog away. Let’s take a closer look the different methods you can use so that you can choose the ones that best suit you.

What Causes Sunglasses to Fog Up?

Sunglasses tend to fog up due to the differences in temperature between the air and the lenses, such as when warm air from the body meets the colder lenses. As a result, the moisture in the air condenses on the lens’s surface, causing them to fog up. 

How to Keep Your Sunglasses Fog Free

There are several easy ways to keep your sunglasses fog free.

One thing you shouldn’t do, however, is use spit or saliva to try to keep the fog away. Saliva can contain bacteria and other impurities that can damage the lenses. Additionally, saliva can leave a residue on the lenses, making them slippery and difficult to use

Now, let’s get into the more useful options:

Solution 1: Wash Them With Soap and Water

Cleaning your sunglasses with soap and water is a simple and efficient way to keep them from fogging up. 

Skin oils and other substances from makeup and hair can accumulate on the lenses and cause them to fog up. To prevent this, regularly wash the sunglasses.

The best way to wash your sunglasses is to rinse them with warm water to remove dirt and debris, then apply a small amount of mild soap to the lenses. Rub the soap in circular motions to remove any oils or other substances. 

Make sure that the front and back of the lenses are cleaned, and then rinse them thoroughly with warm water to remove the soap residue. 

Regular cleaning with soap and water will prevent fogging, improve lens clarity, and protect the lenses from scratches and damage.

Solution 2: Use Shaving Cream

Shaving cream is another quick and simple solution for preventing foggy sunglasses. 

Apply a small dab of shaving cream to the lenses when they begin to fog up, then spread it evenly and wipe it off gently with a soft cloth. 

The shaving cream creates a thin layer on the lenses, reducing surface tension and preventing condensation. It’s also gentle on the lenses, so there is no need to worry about damaging them. 

When using shaving cream, choose a mild, unscented option that won’t irritate your skin or leave residue on the lenses. 

The process can be repeated as often as necessary to maintain the thin layer of protection.

Solution 3: Anti-Fogging Spray

These specialized sprays create a thin, invisible layer on the lenses, reducing surface tension and preventing condensation from forming.

The application of anti-fogging spray (on Amazon) is also a very straightforward process. 

Using a soft cloth, spray a small amount of the solution onto the lenses and evenly spread it over the surface. 

The solution dries quickly and leaves a thin, long-lasting layer on the lenses, effectively preventing fog formation.

All of these sprays are gentle on the lenses and safe to use. Choose the type of spray that best suits your needs and preferences.

Pro Tip: These convenient sprays can also be used on your regular glasses to keep them fog free!

Solution 4: Hydrophobic Coating

A permanent hydrophobic coating is a great solution for stopping foggy sunglasses. This innovative technology basically creates a barrier on the lenses that keeps water away and prevents fog from forming in the first place.

Hydrophobic coatings are implemented by many of the top sunglasses manufacturers, so you should be able to find a pair that suits your needs and style. One of our favorite options is this pair from TOROE (on Amazon).
