Lens Processing and Technology Technical Committees

Lens Processing and Technology Technical Committees

The standards process serves as a critical foundation for everyone in the optical community. The Vision Council has nine active technical committees and task forces, maintained under either the Lens Division or the Lens Processing & Technology Division, which are charged with developing standards for ophthalmic optics. The committees are composed a group of experts who volunteer to write standardsthat pertain to lenses, frames and optical laboratories and discuss issues including frame manufacturing, standards for lens development and communication tools.

These standards address the safety and quality of our members' products, as well as help level the playing field between competing businesses, optical laboratories and lens and frame suppliers nationally and internationally. Some examples of the standards that have been written through the technical committees include the Data Communication Standard and the Country of Origin for Lenses Standard. The committees have also addressed important industry issues, such as the Lens Impact Resistance guidelines. For a complete review of available standards, visit the Standards section of the website.

Committees and task forces that operate under the Lens Division:

Data Communication Standard Committee and Direct Surfacing Task Force/DCS Unified Task Force

The Data Communication Standard (DCS) Committee and the Direct Surfacing Task Force (DSTF) comprise the DCS Unified Task Force. The DCS Unified Task Force produced and maintains the now-ubiquitous standard by which optical laboratory equipment and optical laboratory software systems interconnect. The DSTF task force extended the DCS to cover the interconnection of equipment, lab software systems and lens design software systems. Because both groups worked with the same standard data format and because there was substantial overlap in participants between the two groups, they were combined once the bulk of the DSTF effort was complete. The direct surfacing standard was folded into the DCS. The DCS is essentially identical to the international standard ISO 16284, which is based on this work.

Lens Marking 2.0 - Laser Committee

Reporting jointly to the Lens Processing and Technology Division and the Lens Division leadership, the Lens Marking 2.0 - Laser committee was formed to create a reference tool for the location and placement of all content information and the readability of that content for both visible and semi visible permanent markings on spectacle lenses. The guidelines created by this group are intended to maximize the accuracy of the automated and manual lens positioning equipment and the reading of those markings when used during the lab processing operation.

Additionally, these guidelines will ensure the accurate verification of the lens design for both the production and retail environments and to allow for wearer understanding and acceptance. The group is comprised of lens suppliers, equipment suppliers and labs.
