DuraVision® Silver is part of the ZEISS DuraVision Premium coatings portfolio and is characterized by outstanding anti-reflective properties.
Because spectacle wearers want to enjoy clear and comfortable vision as well look good with their glasses.
Most coated lenses in the market currently come with a green residual reflection, ZEISS DuraVision Premium coatings have a light bluish residual reflection for:*
Higher luminous transmittance for even clearer vision.**
Cuts distracting reflections on the back surface by 20% for more comfortable, clearer vision.**
Reduces reflections on the front surface by 20% for a better appearance.**
* Depending on the lens material, measured on 1.5 (CR39) lenses with DuraVision Platinum UV (internal testing)
** Comparison with standard green AR coated lenses
- Clearer and more comfortable vision thanks to greater lens clarity
- A better appearance due to reduced reflections
- Superior hardness for durable, scratch-resistant lenses.
... thanks to anti-static and easy-to-clean properties.
... thanks to a blue residual reflection color that increases light transmittance.**
Convential AR coatings produce maximum residual reflectance near the peak sensitivity of the eye. The maximum residual reflection of DuraVision Premium coatings has been shifted to the blue end of the spectrum for reduced visibility.
To offer patients true protection, ZEISS has developed an additional anti-reflective layer on the back of the lens, reducing the indirect light reflected into the eye. This extra layer complements the protection offered by ZEISS UVProtect Technology in all clear plastic lenses, which blocks direct UV rays from the front.
More than 90% of UV radiation comes directly from the front. However, a small part approaches the eye indirectly from the sides and back. As some UV rays may be reflected onto the eye by the back surface of the lens, ZEISS anti-reflective coatings are designed to have low reflectance in the UV spectral range.
Back surface UV protection is now integrated as a standard feature into all premium ZEISS DuraVision coatings.
ZEISS is one of the world’s leading manufacturers of eyeglass lenses, and is committed to delivering maximum precision and comfort. ZEISS designs and produces lenses, instruments and measurement systems, as well as retail concepts and technology services that continue to raise the bar in vision care.
