The demands of everyday life call for hard, dirt-resistant lenses that are easy to clean. This is precisely why hard, anti-reflective lens coatings exist – but it needs to be said that 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 mineral (glass) ZEISS lenses. ZEISS lenses with DuraVision® Platinum AR coating also have a more cosmetically pleasing, blue residual reflex colour that produces over 20 % less luminous reflectance than conventional green AR coated ZEISS lenses..

1. More robust
New ZEISS lenses with DuraVision® Platinum AR coating are three times harder than the previous generation of hard anti-reflective (AR) coated plastic ZEISS lenses1 and 35 % harder than AR coated mineral (glass) ZEISS lenses.2

2. Dirt-resistant
The patented fifth anti-static layer3 prevents the buildup of static electricity. As dust and lint are not attracted to the lens surface, lenses stay cleaner, longer.

3. Very easy to clean
The super-slick Clean Coat makes lenses very easy to clean. Lenses with high contact angles repel oil and water more effectively. ZEISS lenses with DuraVision® Platinum AR coating have a contact angle of more than 110° (lenses without super-slick clean coat: 95°).

4. Anti-reflective properties
A new – and less noticeable – blue reflex colour increases the luminous transmittance of the lens, resulting in even better vision. These lenses demonstrate more than 20 % less luminous reflectance than conventional green AR coated ZEISS lenses.
