Good eyeglass lens coatings are a constant issue among glasses wearers. It's the quality of the coating of eyeglass lenses that makes the difference: How robust is lens coating? How long is its service life? DuraVision Platinum technology, supplied by Carl Zeiss Vision, provides the hardest ZEISS eyeglass lenses ever. This technology gives you a brand-new quality of eyeglass lenses and coatings.
Life is made up of many challenges. Even your eyeglass lenses have to withstand a lot every day. Don't have a microfiber glasses cleaning cloth athand? Quick, careless cleaning is one of the things that damages eyeglass lenses the most. Tiny dust particles on your handkerchief, shirtsleeve or jacket cuff and on the glasses themselves can scratch the lens coatings. That's why you should buy eyeglass lenses that are robust enough to face all these challenges with you.
What criteria do today's eyeglass lens coatings have to meet? One obvious requirement is a high-quality anti-reflective coating that lets you see better and look better. This is accomplished by several anti-reflective coatings on your eyeglass lenses that prevent light coming in at different wavelengths and from different directions from reflecting – in other words, they minimize the resulting reflections.
We speak of "residual reflections" in this context, which any eyeglass lens still has in spite of an anti-reflective coating. Instead of the color green, which is usually used in many conventional eyeglass lenses as the tint for these residual reflections, blue is selected. Because of its different color wavelength, this reduces the residual reflection by 20 percent more than conventional eyeglass lenses with a green residual reflection.
For ZEISS, the area of eyeglasslens coatings has always been extremely important and plays a vital role in the further development of vision solutions. This is above all for historical reasons, because ZEISS is a pioneer in the development of eyeglasslens finishes and developed the first anti-reflective coating in the world back in 1935.
The development of DuraVision Platinum was preceded by intense market research. This confirmed that people who wear eyeglasseswith plastic lenses place a lot of importance on having a lens that is as hard and toughas possible. For this reason, modern eyeglasslenses not only have to have high-performance anti-reflective coating, but must also meet the following requirements (click on the pictures to enlarge):
More robust, dirt-resistant, and easy to clean: Thanks to the hardest ZEISS eyeglass lens ever (up to 3 times harder than previous generations*), Carl Zeiss Vision offers you a two year on new lenses with DuraVision Platinum coatings, which you can easily claim if necessary at your eye care professional's location.
Thanks to the DuraVision Platinum technology, the toughnessof ZEISS eyeglass lenses is significantly increased, as shown bymultiple practical tests during internal performance testing. For example, earlier generations of ZEISS eyeglass lenses with coating and eyeglass lenses coated with DuraVision Platinum were subjected to a realistic hardness test. Cloths with a standard amount of soiling were used to simulate a cleaning intensity that corresponds to the total average time (2–3 years) eyeglass lenses are worn. We investigated what marks and damage the individual lenses bore after this. Unsurprisingly, eyeglass lenses with DuraVision Platinum technology were at the head of the class and showed almost no signs of wear.
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.
Whether with or without DuraVision Platinum – give your eyeglass lenses a good, professional cleaning so that the lens coating will last for a long time. It's best if you always remove dirt and dust from your eyeglasses by rinsing them under running water before cleaning them with a microfiber cloth or having them cleaned in the ultrasound bath byyour eye care professional.
