Are O2OPTIX Custom lenses made of the same material as O2OPTIX?
O2OPTIX Custom and O2OPTIX® are both made of a silicone hydrogel material, but with different formulations. O2OPTIX Custom lenses are made of a new silicone hydrogel formulation, sifilcon A, which is conducive to the high-precision lathing that custom lenses require. O2OPTIX® is made of a formulation called lotrafilcon B. Because O2OPTIX® and O2OPTIX Custom are made of different materials and use different manufacturing technologies, their wear and replacement schedules are different.
