Tangible Hydra-PEG is a novel contact lens coating technology that encapsulates Contamac’s Optimum GP material in an ultra thin layer of a PEG-based polymer, creating a lens surface that is extremely wettable and  lubricious.

Recognising the need for a new technology that could end the frustrations caused by contact lens discomfort, Tangible Science LLC (formerly Ocular Dynamics) sought to develop a technology that would reduce disruption to the ocular surface, caused when placing a lens on the eye, to create a more comfortable wearing experience.  This disruption can be characterised or exacerbated by non-wetting lens surfaces, surface water evaporation, reduced tear break-up time, deposits and friction, all of which have been identified as contributors to contact lens discomfort. 

Tangible Hydra-PEG seeks to tackle those issues by creating a surface that is highly wettable, with increased surface water retention due to the high water content (90%) of the PEG-based polymer.  Additionally, Tangible-Hydra-PEG creates an incredibly lubricious surface that can reduce both protein and lipid deposits, as well as reduce friction caused by the interaction between the lid and contact lens during the blink.
