uvextreme AF is a dual-action coating combining the best anti-fog properties of both hydrophilic and hydrophobic coatings. Hydrophilic coatings (like 4C+) absorb moisture like a sponge while simultaneously releasing it back into the surrounding environment. This type of coating is an effective and ideal choice in most work environments and under normal levels of physical exertion. A significant advantage of a hydrophilic coating is its permanence - it will not wear off after repeated cleanings.
A hydrophobic coating reacts to moisture by activating the treated lens surface, forming a thin, invisible film of water. As moisture builds, the film gets heavier until it flows over the lens surface, creating what is commonly referred to as a "sheeting" or "spreading" effect. A disadvantage of hydrophobic coatings is that the coating can wear off with repeated cleaning or soaking. uvextreme AF is permanently bonded to the polycarbonate lens.
In addition to dramatically minimizing fogging and improving vision, there are several other key advantages to uvextreme AF:
A baseline of anti-fog protection is always maintained due to the permanently bonded uvextreme AF coating properties.
uvextreme AF reduces the attraction of dust and particles. Most lens scratching occurs when these tiny particles rub against the lens during cleaning.
uvextreme AF is resistant to a wide range of chemicals. See for yourself. uvextreme AF is the only solution for anti-fog performance in most extreme environments.
