How to Prevent Your Glasses From Fogging with Anti-Fog Lenses?

Experiencing fog on your anti-fog lenses or glasses can be both annoying and dangerous, not to mention unpredictable and recurrent. So how can fog on your glasses be prevented?

Intelligently designed and incredibly easy to use, Optifog is the definitive solution for those looking to banish the mist and achieve a clearer vision.

What is Optifog?

Optifog is Essilor’s unique anti-fog solution. The system combines two key elements:  A lens with anti-fog top layers and a smart cloth with anti-fog molecules.

Optifog offers dual functionality, being both a fog-free and clear lens at the same time. In addition to repelling fog, it also offers protection against reflections, scratches, and harmful UV rays. What’s more, Optifog lenses can be fitted to both women’s and men’s glasses.

How to Activate the Anti-fog Properties of the Optifog Lens?

The Optifog Smart Textile is a smart cloth that’s coated with anti-fog molecules. It has the power to activate the top layers of Optifog-coated lenses, meaning droplets that would usually inhibit vision spread more evenly across the lens. This results in an invisible and fog-free layer.

Highly technological yet so simple to use, the Optifog Smart Textile was designed to provide optimum anti-fog performance when used in tandem with Essilor’s Optifog-coated lenses.

How to Clean Your Optifog Lenses?

As well as acting as an activation tool, the Optifog Smart Textile can be used to take care of Optifog-coated lenses, ensuring they remain fog-free throughout the day.

It should be noted that the Smart Textile should not be washed and should be changed every three months.

Can I Have Optifog Lenses Fitted to My Glasses?

Yes. Optifog lenses can be fitted to a wide range of men’s and women’s glasses. These lenses can be fitted to new glasses or existing frames using a reglaze glasses service.

Top 6 Benefits of Using Anti-Fog Lenses over Normal Lenses

When it comes to eyewear, clarity of vision is of utmost importance. Whether you wear glasses for daily use or engage in activities that require protective eyewear, fogged-up lenses can be a frustrating hindrance. Fortunately, advancements in lens technology have led to the development of anti-fog lenses, which offer numerous advantages over traditional lenses. In this article, we will explore the benefits of using anti-fog lenses and how they can enhance your visual experience.

1. The Problem with Fogging:

Fogging occurs when the temperature of the lens surface is different from the surrounding air, causing moisture to condense and form tiny droplets on the lens. This phenomenon is commonly experienced when transitioning between different temperatures, such as entering a warm room from a cold outdoor environment or engaging in physical activities that cause perspiration. Fogged-up lenses can impair your vision, making it difficult to focus and perform tasks effectively.

2. Enhanced Clarity:

One of the key benefits of anti-fog lenses is their ability to maintain clear vision in challenging conditions. By incorporating a special coating, these lenses prevent the accumulation of moisture and eliminate fogging. This feature ensures that you can see clearly at all times, whether you are in a humid environment, exercising, or transitioning between temperature extremes. With anti-fog lenses, you can say goodbye to constantly having to wipe your lenses or squinting through foggy vision.

3. Improved Safety:

For individuals engaged in various sports or outdoor activities, safety is paramount. Regular lenses tend to fog up during physical exertion, compromising your ability to see potential hazards clearly. Anti-fog lenses offer a significant safety advantage by providing uninterrupted visibility. Whether you’re skiing down a slope, playing a game of soccer, or working in a hazardous environment, these lenses ensure that you maintain a clear field of vision, reducing the risk of accidents and injuries.

4. Convenience and Time-Saving:

One of the most frustrating aspects of fogged-up lenses is the constant need to clean them. Traditional lenses require frequent wiping, which can be time-consuming and inconvenient, especially when you are on the go. Anti-fog lenses eliminate the need for constant cleaning, allowing you to focus on your activities without interruptions. This convenience not only saves time but also prolongs the lifespan of your lenses by reducing the wear and tear caused by excessive wiping.

5. Versatility and Adaptability:

Anti-fog lenses are available in various forms, catering to different visual needs. They can be incorporated into prescription glasses, safety goggles, sunglasses, and even camera lenses. This versatility ensures that you can enjoy the benefits of fog-free vision across different aspects of your life. Whether you need corrective lenses, protective eyewear, or sunglasses for outdoor adventures, anti-fog lenses offer a versatile solution that adapts to your specific requirements.

6. Long-Term Cost Savings:

While anti-fog lenses may have a slightly higher upfront cost compared to traditional lenses, they offer long-term cost savings. The durability and resistance to fogging mean that you won’t have to replace or clean them as frequently, reducing the overall maintenance and replacement costs. Additionally, by eliminating fogging and maintaining clear vision, these lenses can prevent accidents and potential damages that may occur due to impaired visibility, further saving you from unexpected expenses.


Anti-fog lenses have revolutionized the eyewear industry by addressing the common frustration of fogged-up lenses. Their ability to provide enhanced clarity, improved safety, convenience, versatility, and long-term cost savings make them an excellent choice for individuals of all walks of life.
