Optifog anti-fog system
=========================
Fog-free, clear vision with the Optifog system
----------------------------------------------
All glasses wearers have at some point encountered misting/fogging or ‘steaming up’ of their lenses. This is especially true when wearing face masks as the difference in temperature between the cold surface of the lenses and your hot breath causes water vapour to condense on the surface of the lens, obscuring your vision. The Optifog system stops this from happening, allowing you to work safely and effectively, with no distractions.
Optifog's unique anti-fog system combines two patented technologies: Optifog lens treatment and a smart textile cloth with anti-fog molecules that activates the power of the Optifog lens. Simply wipe your lenses with the smart cloth and droplets that would usually obstruct your vision spread uniformly across the lens, in an invisible and fog-free layer.
 Both the front and back surfaces of the lens have integrated anti-fog technology
**Fog repellent**
Stays fog free even in extreme conditions\*
**Scratch-resistant**
Durable lenses, ensuring clear vision
**UV protection**
Protects your eyes from UVA and UVB rays
**Glare reduction**

**Dust repellent**

### Fog-free glasses in the workplace
In addition to its activation efficiency, the Optifog Smart Textile can be used every day to take care of your Optifog lenses.
**Every day**
Clean your Optifog lenses using the Optifog Smart Textile that comes with your new lenses.
**Every 2 weeks**
Wash your Optifog lenses with water. To avoid contamination, it is recommended to wash your glasses after they have potentially been exposed to infected agents.
**Every few months**
(or after 450 activations): Renew your Optifog Smart Textile.
Before handling the Optifog Smart textile, it is recommended to wash your hands and spectacles to avoid any contamination.
