By: Luzerne Optical Laboratories, Ltd.


Luzerne Optical is one of the largest optical manufacturers of Free-Form lenses in the United States. Free-Form is also known as:  FreeForm, Digital Surfacing, Digitized, Internal Free-Form, FingerPrint Surfacing, Customized, Precise-Form, Backside/ Back-Surface, Dual-Surface, Wavefront, Fully Personalized, HD and High Definition. 

Our optical laboratory has made substantial investments in highly sophisticated proprietary software and CNC multi-axis surfacing technology systems to produce these complex lens surfaces precisely.  Hi-tech measurement systems are used to continuously monitor product quality.  Our lab can process any type of lens, from standard spheres and torics to complex free-form surfaces in both single vision and progressives with superior optics.  This new surfacing technology creates a significant improvement over traditional processing by allowing production within 1/100 of a diopter in accuracy.  Our natural diamond generating technology delivers the lens geometry and surface shape required within the tolerance of single microns.  This efficient system eliminates thousands of traditional hard lap tools with a minimal amount of soft tools following an intelligent computer controlled polishing system that conforms to complex changing surfaces. Our free-form system calculates for aberrations and can correct them for a superior design.  A special laser is used to create the finest and clearest markings on a variety of materials for progressive lenses produced. 

Some digitally surfaced free-form lens designs will take into account measurements such as pantoscopic tilt, vertex distance, near viewing distance, panoramic angle and wrap angle.  This process allows our lab to provide truly customized lenses for individual wearers.  Some free-form lens designs are delivered with a compensated Rx form for power verification.  These lens designs were optimized for the position of wear creating small power changes to reflect the fitted lenses as they are perceived by the actual person wearing the glasses.
