Specialty Optics is a product line of DAC International, Inc.

DAC International, founded in 1964, is a manufacturer of CNC equipment for the production of contact, intraocular and spectacle lenses, and has become a pioneer and leader in the development of machines that accept inputs to create Freeform® designs.   

DAC offers the RxD Spectacle Lens Lathe, a high precision, diamond turning machine for back surface generation, and the Soft Lap Polisher (SLP), the only polishing system that can be used to polish freeform® lens designs without special adaptation.

Because of patent issues surrounding the technology of turning the Rx and the add on the backside of spheres, DAC has been unable to actively promote this feature.

Therefore, in order to utilize the capability of the RxD Lathe and Soft Lap Polisher (SLP), DAC developed the software to create a Specialty Lens Menu, which provides the means to take low-cost lens blanks, backside of spheres and turn them into: Slabs, Round Seg Bi-Focals and Lenticulars.

Towards this end, DAC established Specialty Optics as a laboratory operating from its Carpinteria facility, where specialty lenses are produced for labs only.

Specialty Optics Lab Manager, Jim Marks, joined DAC International in 1996, where he served as Applications Manager.  With ten years experience in software development and lens design, Jim now oversees the production of specialty lenses and the testing of new designs and equipment.
