Spectacle lenses with DuraVision® Platinum technology are made up of nine ultrathin layers that are applied directly to each other. These layers have four tasks to perform: first the base glass is hardness coated, followed by the different anti-reflective coatings including an antistatic layer, finally followed up by the Clean Coat. This topmost layer seals the lens and creates a perfectly smooth surface. Dirt and moisture drip off, making it easy to clean the spectacle lens perfectly.
The secret of DuraVision® Platinum, however, is the ion-assisted coating technology. Special ions transfer their kinetic energy to the spectacle lens. In the Carl Zeiss coating systems, the lenses are "bombarded" with these ions over and over throughout the coating process. This ensures optimum compaction and adherence of the individual layers to each other. This closely bonds the otherwise "loose" layers to each other. This way, the individual layers can be joined together in a perfect fit, like a three-dimensional puzzle. Of course, this process takes place at the micron range and is not visible to the naked eye. The result is a lens surface that is three times harder than the previous generation of ZEISS plastic lenses*. This very smooth and hard surface finally makes it possible for spectacle lenses to be more robust, dirt-resistant, and easy to clean.
