Plasma technology



Plasma is a gas made of electrically charged particles and sometimes referred to as matter in the ‚4th state‘ because of how its behaviour differs from  solids, liquids and gases .

Plasma surface treatment at SwissLens is used to overcome the inherent hydrophobic properties of modern contact lens materials. The lens surface is plasma treated, rendering them wettable to tear fluid and maximizing lens wear comfort.
