At first sight, every lens looks clear and transparent. Under a microscope, however, minimal opacities, micro particles and streaks make all the difference between premium and poor quality lenses.
Branded lenses from ZEISS are in a quality class of their own. Clarity is the byword for premium ZEISS quality – and the guarantee that all of the processes that enable ZEISS quality have been met:
- Purity of raw materials – with the aid of filter technologies developed by Carl Zeiss, the raw materials are first cleaned before processing in order to remove any inclusions and prevent subsequent opacities or streaks.
- Stringent quality test specifications
- Use of lower tolerance tooling for more accurate powers
- Use of see through power measurement rather than surface power measurement
- Matching of coating design to different base lens materials
- Development competence of the highest level – certified to ISO 9001/2000.
The production of lenses featuring unique ZEISS Clarity quality is the result of “Ultra Vision” competence from Carl Zeiss. This competence is based on the development of lenses for use in extreme conditions in microsurgery, space, camera optics – and on the 160 years of in-depth research conducted by ZEISS into the optimum interaction of the eyes with lenses in optical systems.
