Experiencing fog on your spectacles 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 clearer vision. What is Optifog? Optifog is Essilor\u2019s 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\u2019s 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\u2019s 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.
