Lens coatings are like finding the right coat to match the perfect dress or suit: they provide everyday protection for your spectacles. A modular system which allows you to choose what you want – to ensure that you receive the right lenses to match your appearance, meet your requirements and provide the kind of performance you expect from your spectacles. ZEISS therefore offers two options for its lens coatings: GOOD and BEST.
The R&D Department at ZEISS has conducted detailed research into what spectacle wearers expect from the performance of their lenses. If spectacle wearers were asked what properties of lens coatings they value most, 7 out of 10 cite scratch resistance and durability as the most important for them. This is not surprising in view of the many challenges confronting our spectacles in everyday life.
And, of course, crystal-clear vision, an attractive appearance and optimum cleaning properties are no less important.
Choose DuraVision® Platinum or LotuTec®: ... thanks to basic hardness, anti-static and easy-to-clean properties.
Choose DuraVision® Platinum:... thanks to 20% less irritating reflections (comparison with Standard green AR coated ZEISS lenses).
Choose BEST, DuraVision® Platinum:... thanks to nine layers densely packed through ion bombardment.
|1. Your new spectacles are intended as a second pair (reading glasses, substitute for contact lenses...).
|2. Your new spectacles must be affordable.
|3. You will not wear your new spectacles very often.
|4. The quality of the anti-reflective coating must be good, but not top of the range.
|5. Your new spectacles are only a temporary solution and do not need to offer maximum service life and comfort.
|1. Your appearance with your new spectacles is very important to you.
|2. You find reflections very irritating.
|3. You want to enjoy crystal-clear vision with no reflections on your lenses.
|4. Your new spectacles are intended for everyday use.
|5. You want the most modern anti-reflective coating technology available today.
|6. Your new spectacles are intended for everyday use and you will be totally reliant on them.|
|7. You expect your new spectacles to stand up to your very active lifestyle.|
|8. You want the hardest lenses available from ZEISS.|
|9. You want a perfect appearance with your new spectacles. The lenses must display no reflections – either visible for yourself or for others.|
|10. You want the most modern anti-reflective coating technology available today.|
If three or more of these statements apply to you, the standard lens coating would be sufficient for your needs.
If three or more of these statements apply to you, you should not make any compromises when purchasing your new spectacles and opt for DuraVision® Platinum.
The standard ZEISS lens coating offers you a package comprising:
Imagine you are wearing a beautifully soft woolen sweater. Unfortunately, the fluff keeps sticking to your lenses. In your job, you often have to spend time in dusty rooms; afterwards, your lenses look like they have been in a desert storm. It starts to rain and you have no umbrella at hand. With the raindrops on your lenses, you can see next to nothing. All these are examples of situations which reveal the true performance of lens coatings.
Clean-Coat and anti-static coatings which are featured on all LotuTec® and DuraVision® Platinum by ZEISS make the lenses anti-static and water-repellent. A coating is available for spectacle lenses that feature much the same lotus effect as the finish used on cars or other smooth surfaces, although a different technology is used. In lenses with a LotuTec® coating, the lens surface is smoothed to such an extent by the coating that dirt particles or droplets of water simply bead off it. The lenses are therefore easier to clean and require less frequent cleaning. Even greasy fingerprints can be effortlessly removed from the lens.
DuraVision® Platinum offers you:
The DuraVision® Platinum coating by ZEISS uses innovative coating technology that makes your lenses a real masterpiece of optics. Anti-reflective coatings normally have a greenish hue known as the residual reflection. You can see this if you hold the lens against a white surface, but you are not aware of it when you are actually wearing the lens. For technical reasons, every coated lens displays a residual reflection.
The blue residual reflection seen on DuraVision® Platinum from ZEISS is much more comfortable for the eyes, but also much more complex to produce.
The key benefit: A blue residual reflection increases the light transmission of the lens, i.e. the amount of light reaching your eye. More light passes through the lens and more reflections are eliminated. DuraVision® Platinum by ZEISS guarantees more light transmission from the front to the back surface of the lens.
As we said before: If spectacle wearers were asked what properties of lens coatings they value most, 7 out of 10 cited scratch resistance and durability as the most important for them. This is not surprising in view of the many challenges that await us in our everyday lives.
Spectacle lenses must be able to stand up to the rigours of modern life and be hard enough to overcome the many challenges we face at work and in our leisure time. They must be robust, dirt-repellent and easy to clean and, of course, they must also provide crystal-clear vision. The answer: DuraVision® Platinum, the all-in-one coating from ZEISS. It is the hardest coating ZEISS has ever made!
In a process called “ion bombardment,” ions transfer their kinetic energy as they strike the surface of the spectacle lens. This densely packs the different layers of the lens, making it much harder and its surface even smoother.
