Zero-Fog minimizes surfaces form fogging when going from warm to cold areas or vice versa and dissipates electric charges that will eliminate dust attraction. 

Zero-Fog is formulated with safety in mind in order to avoid discomfort and any eye reactions. This formula is also compatible with anti-reflection coated surfaces. 

Please keep in mind that Zero-Fog is a treatment and not a lens cleaner and is less effective on hydrophobic lenses. 

Cleaning the lenses prior to applying the Zero-Fog treatment is essential to its success.  The lens surface must dry out for at least one hour after applying the Zero-Fog treatment, if Zero-Fog is not left to dry properly it may cause some eye irritations.
