It’s all down to PC Technology, which is within the Proclear toric lens. PC stands for phosphorylcholine, which contains molecules that are hydrophilic and biocompatible with the human body. Thanks to PC Technology, Proclear toric will hold water for longer periods of time and have less surface evaporation. PC Technology also attracts and binds water to the lens surface – and a shield is created that keeps the lenses clean and functioning properly. It all means that Proclear toric remains hydrated, which helps them feel moist and comfortable all day long.
