Almost every day, there is new information about the customs dispute. This makes it more challenging than ever for decision-makers to develop long-term business strategies. Here you get hints on how to deal with the uncertain situation.

The constant stream of updates on the customs dispute makes it harder than ever for decision-makers to plan for the long term. An interview with Omar Elkhatib.

The production of spectacle lenses is an art in itself. Especially, the cleaning and coating process in particular should be carefully thought out and implemented to ensure minimal breakage. This article should give insights into best practices involved in these essential stages of the lens manufacturing process.

Before 1980, aspherical surfaces were only used on high-power plus spectacle lenses that lie beyond the range of powers that can be corrected for aberrational astigmatism with spherical surfaces. In recent years, this has changed and once again this was made possible by the development of freeform machining.

Yes, we live in a digital world. And yes, we not only use emails as a matter of course, but also business messaging service providers such as WhatsApp. But although these digital systems offer many advantages, the question remains as to whether we, as participants in the popular online dialog, would sometimes prefer to have a human contact.

Freeform technology brought the possibility, not only of optimizing the performance for any individual prescription, but also of varying the design characteristics of the lens by incorporating more fitting data relating to the facial characteristics of the wearer. That is, the lens could be optimized and personalized.

The perfect surface – lenses between human and machine The EssilorLuxottica Group operates hundreds of ophthalmic lens production facilities worldwide. Some of them are located in Europe, and one plant is even in the middle of Germany. For 80 years, high-quality ophthalmic lenses have been manufactured in Braunschweig.

Based on 20 years of experience, a world-renowned Japanese manufacturer has completed a fully
automated dry tinting system. The digital tinting method works completely differently compared to
traditional dipping and is said to have a number of advantages in terms of productivity, environmental
impact, and material versatility as a result.

Without doubt, the most significant development in spectacle lens design is the change in the
manufacturing process from lapping to computer numerically controlled milling methods usually
referred to as freeform or digital surfacing. The first part of this paper is designed to remind you of the principles of design which have led to the modern personalized and optimized progressive power lens.
