Eyeglass 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 given a hardness coating, followed by the different anti-reflective coatings including an anti-static layer and finally by the CleanCoat. This top layer seals the lens and creates a perfectly smooth surface. Dirt and moisture simply roll off, making it easy to clean the eyeglass lens perfectly.
The secret of DuraVision Platinum, however, is the ion-assisted coating technology. Special ions transfer their kinetic energy to the eyeglass lens. In the Carl Zeiss coating systems, the lenses are "bombarded" with these ions over and over throughout the coating process. This ensures optimal compaction and adherence of the individual layers to each other, with tight bonding of 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 level 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 extremely smooth, hard surface gives eyeglass lenses even greater resistance to moisture, dirt and scratches, and makes them easy to clean as well.
Tips for keeping them sparkling
Something everyone thought impossible in the past: progressive lenses that are as individual as their wearers are now the measure of all things.
