Understanding Digital Lens Technology

Digital lens technology or free-form is an improved method of lens manufacturing that utilizes five axis surfacing equipment for superior lens production.

This new generation of surfacing equipment eliminates the need for traditional hard lap tools while using a minimal amount of soft tools thus decreasing the amount of "rough" surfacing found in a traditional lens.

The polishing process utilizes an intelligent computer controlled system that conforms to the complex changing surfaces of the lens for enhanced optics.

Most digital lenses use either a digital mold on the front and digital surfacing on the back or digital surfacing on both surfaces for a design with tighter tolerances and enhanced visual acuity.
