First and foremost, Carl Zeiss stands for accuracy, clarity, and reliability. Our brand can convey these values best when it has a dominant position on a white background. Thus, the environment in which our trademark is placed becomes part of the logo and supports the statement made by the latter.
Of course, we hope that you will also place our logo on a white background on your website, but we do not want to intervene in the design of your website or dictate the backgrounds to be used. For this reason, our downloadable logos are equipped with a white frame that gives the logo its required breathing space and, regardless of the actual background color of your website, provides optimal contrast.
DuraVision® BlueProtect by ZEISS is a coating specially developed for people who spend a lot of their time indoors and are exposed to blue-violet light from LEDs as well as TV, computer or tablet screens.
ZEISS DuraVision® BlueProtect reflects parts of the blue-violet light emitted by these sources, preventing light from entering the eye.
This ZEISS coating reduces the transmission in the spectrum of 380–455 nm (blue light hazard) to a BPI 15 while keeping the high transmission level above 460 nm.
Blue-violet light is everywhere, although its intensity varies greatly.
While a typical LCD computer monitor produces a brightness of 250 cd/m2, a clear blue sky at midday is 32 times as bright. Direct sunlight can be thousands of times as bright.
To meet the challenges of everyday life, we need hard, dirt-resistant lenses that are easy to clean. This is precisely what hard, anti-reflective lens coatings offer – but the quality of these coatings can vary greatly.
What makes ZEISS lenses with DuraVision® Platinum AR coating different? These hard and light lenses are very robust, dirt-resistant and easy to clean while offering first-rate anti-reflective properties. An integrated system of coating layers densely packed using ion-assisted deposition results in a lens surface that is three times harder than the previous generation of hard anti-reflective (AR) coated plastic ZEISS lenses and 35 % harder than AR coated glass ZEISS lenses*. ZEISS lenses with DuraVision® Platinum AR coating also have a more cosmetically attractive, blue residual reflection colour that generates over 20% less luminous reflectance than conventional green AR coated ZEISS lenses.
