Antiviral treatment on optical glasses

The Covid-19 pandemic has been more than an upheaval in our lives: it has induced lasting changes in our habits and in our daily behavior. Thus, we learned the importance of barrier gestures, essential to “break” the chain of transmission of a disease. We regularly use disinfectants, we have adopted new social uses (wearing a mask in public, greeting each other with the elbow, etc.), we have also discovered that we must be wary of automatic or reflex movements which, unconsciously, can contaminate .

Indeed, it has been scientifically proven (2) that each of us touches our face 23 times per hour and that 44% of these contacts involve the mouth, nose or eyes.

For spectacle wearers, this is not trivial, because they conceal a considerable microbial load: more than 5,000 viruses and bacteria proliferate on the lenses and 64% of the microbes found on the glasses can cause disease. skin or eyes (3).

And these pathogens are able to survive from several hours to several days (4): the virus responsible for Covid-19 can thus remain active and infectious for up to 72 hours on stainless steel and plastic (5)!

A drink… against everything!

In an Ipsos study for ZEISS in March 2021 conducted on a representative sample of 1,086 French people aged 16 to 75, focusing in particular on their expectations for simple and practical solutions to protect themselves (and others) from the coronavirus, 64% of people interviewed were interested or very interested in antiviral spectacle lenses, which kill viruses and bacteria.

ZEISS meets this demand with ZEISS DuraVision® AntiVirus Platinum UV, the first self-decontaminating lenses that kill 99.9% of viruses and bacteria.

An original technology, incorporating for the first time in an anti-reflective agent an antimicrobial agent proven for centuries, silver - a metal whose medicinal benefits Hippocrates already knew.

And this new functionality does not alter the previous ones in any way: the ZEISS DuraVision® AntiVirus Platinum UV treatment therefore adds this bactericidal and virucidal action to the list of characteristics of the brand's lenses: superior resistance to scratches and soiling (oleophobic, hydrophobic lenses , antistatic), UV protection, transparency, as well as aesthetics.

It is, in short, the optimal barrier… without making the slightest gesture.
