Newer soft lens materials include silicone-hydrogels to provide more oxygen to your eye while you wear your lenses. Centre thickness Eye Contact Lens. They have a modulus of 0.6MPa and a Dk/t of 90. With these lenses we see a higher Dk with higher water content than would be expected with first generation lenses, and correspondingly lower modulus, related to the higher water content.
