PLASTIC LENS COATINGS.

Hard Coatings:
Lens Hard coatings act as a protective coating and enhances the performance and longevity of plastic Lenses. 

Benefits of Hard Coatings: » Scratch Resistance: Hard coatings significantly increase the scratch resistance of plastic lenses, which are naturally softer and more prone to damage than glass lenses. » Durability: These coatings enhance the durability of lenses, allowing them to withstand daily wear and tear without compromising visual clarity.

Anti-Fog Coatings.
Anti-Fog and Anti-condensation coatings help prevent fog and condensation of water droplets on the lens surface.

	UNDERSTANDING FOG Fog consists of many water droplets. It is formed by ambient humidity which condenses into small droplets on a surface. There are different factors that influence the formation of fog: »  The temperature difference between two environments. »  The relative humidity of the warm environment the lens wearer has entered.
	AN EFFECTIVE SOLUTION AGAINST FOGGING Optifog is Essilor’s smart and unique anti-fog system: a lens with anti-fog top layers and an Optifog activator cloth with anti-fog molecules that activate the power of the Optifog lens. Just wipe your lenses as usual. The molecules in the activator cloth activate the coating on the lens to maintain the anti-fog properties, just by wiping your lenses!
