I have explained why the two are marketed differently (money, FDA extending SilHydro lenses from two weeks to one month, etc). I am not asking anyone to believe me, but retrace the thread and READ what CIBAVISION says about their own lenses. READ. READ.. READ. Better yet, take the FLYER I linked to, print it out, and take it to your eye doctor.
