Proclear contact lenses from Coopervision feature a revolutionary new design utilising natural materials allowing Coopervision to refer to them as biocompatible. A substance produced naturally in the human body called Phosphorylcholine which aids in water retention in the cell membranes has been used by Coopervision to engineer a material which ensures your lenses remain moist and comfortable throughout the day. Proclear lenses are available for wearers with astigmatism in the form of Proclear Toric and Proclear Multifocal are available for users who suffer from Presbyopia.
