Anti-fog > prevents condensation and garantees maximum longevity.
Anti-reflective > reduces eyestrain and eliminates interference glare.
Brunishing > improuves filtration of visible light
Flash finish > improuves filtration of visible light by producing a mirror effect on the lens.
Water-repellent > makes water slide over the lens and prevents hydrogen bonds forming between water molecules. Visibility is impouved
Oil-repellent coating > prevents finger marks, makes water slide over the lens and cleaning easier.
