Carried out by an external laboratory, the DK value measurements of HydroColor and HydroColor Pro colour lens have revealed that the colour did NOT impact the oxygen permeability in any way. The uncoloured material (Contaflex 67%), as well as the coloured lens, shows the same DK value. The same applies to the prosthetic HydroColor Pro with its opaque layer.
Thus, the lenses along with a high water content material as well as a thin lens design without sandwich configuration provide the users with high physiological comfort.
The use of unapproved contact lens care products will destroy the colour of the contact lens. Only use the following tested and approved products view more
