Tony Hough, Director,
CLS Software Limited

Our aim is to facilitate stakeholder affection and appreciation through the provision of specialist high value contact lens design and related manufacturing and lens-fitting systems.

Our core tools are tLab and tLink which have many customisable applications and processes. We adapt, add on and develop new features as required to enable our clients to operate at their peak.

We began in 1992. Since then we have worked with many great companies, big and sometimes small: Novartis, Johnson & Johnson, Bausch & Lomb, Sauflon, Contact Lens Technologists Pte, MJS Automated lens Technology, No 7 Contact Lens Laboratory, Cantor + Nissel, Con-Lens, Lambda-X, PhaseFocus, Visionix, Rotlex, Contamac, Vista Optics, … and on.

We believe in value, peak performance, uniqueness, whole systems, a fair partnership; and the power of strong insights to lens design, functionality, on eye performance and manufacturing process. Our clients ask us back again and again; we believe this is the best testimony to the quality of our work.


We also work in partnership with other agencies and consultancies and with a strong collaborative network of associates. In particular we have long established business partner relationships with Sterling UltraPrecision (Ametek Inc) and DAC International Inc.

We are strengthened by our ties with the University of Manchester and the University of Bradford in the UK. Tony Hough, founder of CLS Software, is a leading authority on lens design and manufacturing and a Visiting Scientist at the University of Manchester. This has led to even better insights, tools and methods that can really add value for clients.
