Eyeglasses become foggy with temperature change, always from a cold to a hot environment.
Fog on lenses depends on different factors:
* The temperature difference between the two environments
* Relative humidity in the hot environment entered by the wearer
* Time of exposure allowing the lenses to adopt the surrounding temperature
Fog may happen at every moment of the day, in everyday life situations.
1. Changing environmentMoving from cold to hot environment like getting out of an AC environment or coming in a heated place is always creating fog on wearers eyeglasses.

2. Indoor activities
Driking hot beverages Eating hot food
Boiling a pot of water Opening the dishwasher
3. Outdoor activitiesFog happens on lenses when playing sports such as running, cycling, playing tennis, skiing…

What is Optifog system benefit vs antifog liquids?
Other systems are sold on the market but with less anti-fog efficiency and less everyday clarity of vision. Optifog also provides a more durable solution than its competitors: the anti-fog coating of Optifog durably retains the Optifog Activator for up to one week, under normal conditions.
Moreover anti-fog liquids sold on the market have very variable quality. Even the most efficient of them can bring only anti-fog properties on standard lenses from a couple of hours up to one day. And some fog can remain on the lens.
May I activate Optifog lenses with another anti-fog liquid? Optifog maximum anti-fog efficiency depends on the perfect interaction between the lens and the Optifog Activator. The lens has been specifically designed to protect against fog. The Optifog Top Layer has been specifically developed to bring maximum efficiency with Optifog Activator. When other anti-fog liquid are used performances are much lower and can be disappointing for wearers.
Is Optifog a patented innovation? Optifog is a technology covered by an international patent application.
