The coating of every DuraVision® Platinum lens consists of nine ultra-thin layers: first, the base lens receives a hard coating, followed by various anti-reflective coatings including an ant-static coating, and then finally by the Clean Coat layer. This topmost layer seals the lens and creates a perfectly smooth surface. Dirt and moisture bead off to enable a perfect, easy-to-clean lens.
However, the extreme hardness of DuraVision® Platinum can only be achieved by a special coating technology. The lenses are repeatedly bombarded by special ions during the production process. These transfer their kinetic energy to the lens and optimally compact the layers into one single coating. This ensures optimum adherence of the individual layers to each other. The result is a lens surface that is three times harder than the previous generation of ZEISS plastic lenses*. It is this very smooth and hard surface that makes the lenses more durable, dirt-resistant and easy to clean.

One lens coating plays a key role in how well you see and how good you look: the anti-reflective coating. New coating technology is therefore used for the DuraVision® Premium coatings, Silver and Platinum. This is discernible from the blue residual reflection that you can see if you hold the lens at an angle against a white background. Every lens with an anti-reflective coating displays this residual reflection which, however, is green in many traditional lenses.
For its Premium coatings, ZEISS uses a blue colour which is more complex to produce, but allows more light to reach the wearer's eyes – a definite benefit for better vision. Reflections are reduced on both the front and back surfaces of the lens.
My ZEISS lenses with DuraVision Platinum are superb. I’ve been wearing them for the past 18 months and they’re still relatively scratch-free. It’s really amazing! My old lenses had really bad scratches and the coating was already starting to peel off. That’s certainly not the case with DuraVision Platinum. And I even wear my spectacles when I’m out gardening.
