SAM® Technology (spherical aberration management) is an award winning system, involving the computerized plotting of thousands of lathing points. SAM® software enables computer controlled lathes to produce extremely accurate aplanatic optics resulting in greatly enhanced clarity of vision across the whole of the lens surface. Additions lenses use SAM® technology to create a front multifocal surface, which means the existing Ledaperm or Profile Aspheric lens wearer can be refitted with new multifocal lenses using the same back surface fitting characteristics of their existing lenses. We are calling these new lenses LEDAPERM ADDITIONS and PROFILE ADDITIONS.
