Some viruses remain viable on surfaces for anything from several hours to several days, while others can even remain infectious for 2 months or longer. Viral pathogens usually survive longer on non-porous materials (like plastic surfaces) than on porous materials like textiles.4
The virus that causes COVID-19 (SARS-CoV-2) can also survive on surfaces over time. A recent study suggests that the virus can remain viable and infectious up to 72 hours on stainless steel and plastic.2
DuraVision® AntiVirus Platinum is an antiviral and antibacterial coating that actively fights and kills 99.9% of potentially harmful viruses and bacteria on the surface of the lens1, helping to improve spectacle lens hygiene.
ZEISS lenses with antiviral and antibacterial coating also provide full UV protection up to 400 nm, even in clear lenses.4
For those who want anti-smudge glasses, these lenses offer all the benefits of our most premium lens coating – ZEISS DuraVision Platinum. The coating is designed to feature low reflectance and the less visible blue residual reflex ZEISS is famous for. These lenses are also optimised for high scratch resistance and are easy to clean.
We’ve developed technology that transfers antimicrobial silver into an anti-reflective coating layer that can be applied to the surface of a spectacle lens:
Silver is well established in science as a long-lasting antimicrobial (antiviral and antibacterial) agent. ZEISS developed technology to incorporate this proven approach as another feature of the premium anti-reflective coating so that viruses and bacteria that land on the lens surface are killed and inactivated.
Through a special vacuum coating process, silver is deposited on the surface of the lens at high temperatures. ZEISS DuraVision AntiVirus Platinum UV contains embedded antimicrobial silver within the coating structure. The silver within the coating releases silver ions (Ag+). These silver ions (Ag+) deliver proven antiviral and antibacterial interaction on the lens surface.
This product is tested and proven in compliance with the established ISO standards for antiviral or antibacterial testing by external laboratories and institutes located in China, Germany and Canada.
Bacteria and viruses are found on high-touch items, including spectacles. Your lenses can be easily contaminated through direct contact and droplet spread:
