Recently a new material called "FloShield Air System Vision System" has been proposed and has the particularity to combine both anti-fog product and a temperature control system in contact with the lens in order to fight against condensation and smoke. The purpose of this is to improve the quality of vision by reducing the fogging phenomenon and no change of the temperature in contact with the lens (moisture reduction). Accordingly, it is assumed a reduction in the number of stay and a reduction in the specific operative time associated with this cleaning.
