The global COVID-19 pandemic has drastically influenced our awareness of viruses and their consequences. We’re more focused on the presence of germs and how they spread than we’ve ever been before.
With this increased awareness, you may have heard of the term “high-touch items”. These include things we touch on a regular basis that can impact our general hygiene. Spectacle lenses are high-touch items that can potentially have viruses and bacteria on the surface.
Better spectacle lens hygiene
DuraVision AntiVirus Platinum is an antiviral and antibacterial coating that actively inhibits 99.9% of potentially harmful viruses and bacteria on the surface of the lens, helping to improve spectacle lens hygiene.
ZEISS lenses with antivirial and antibacterial coating also provide full UV protection up to 400 nm, even in clear lenses.
Use of silver as antimicrobial agent
The healing properties of silver have been known for centuries and are well established in science and medicine. 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.
Vacuum deposition and material science
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.
