Engineering Department CAD DrawingsOver the past 30 years, the DAC International Engineering Department has been headed by Rod Keller, who is credited with design of the world’s first computer-controlled contact lens lathe.  In 1993, Rod received the Contact Lens Manufacturers Association (CLMA) Trailblazer Award.

Our team of mechanical, electrical/electronic, software and applications engineers are constantly seeking to expand and improve the capability and reliability of our equipment.  Our lathes can be outfitted with a variety of options including automation, laser marking, haptic milling, and reference mark locating.

Among our many proprietary developments are the Digital Motion Control (DMC) which interfaces with the on-board computer and controls the motion and functions of the lathe, and the reaction elimination system, which holds all surface influencing vibration to a minimum.

DAC’s Software and Applications Departments have developed the industry’s most comprehensive lens production software – easy to use and easy to customize.  Full maintenance and calibration features are built into the software, as well as on-line editing. Specialty lens design capability, includes torics, aspheres, slab-offs, bifocals, wavefront and points files.
