The face masks could be disposable or washable depending on your routine or work schedule. The use of face shield is offering better protection irrespective of your workflow and its so comfortable. The face shields protects from dust, spills and aerosol sprays.
The advantage of the face shield over the face mask is the fact that your entire face is protected with an added advantage of protecting your eyes. Corona virus has been reported to be transmissible through eyes.
The use of face shield offers protection from the virus as it creates a barrier between you and the next person and per adventure the person is asymptomatic and sneezes you are protected.
A recent study gives credence to this fact that except you are working in the hospital or taking care of a Covid-19 patient then the face shield is your choice. Call to order your chemically treated face shields today.
Face shield must be worn for optimal protection, the shield should extend below the chin , to the ears laterally, and there should be no exposed gap between the forehead and the shield’s headpiece. Clinical studies shows face shield is the most important for optimum protection.
Face shields offer a number of advantages. The surgical masks have limited durability and no potential for reprocessing, face shields can be reused indefinitely and are easily cleaned with soap and water, or disinfectants.
They are comfortable to wear, protect the portals of viral entry, and reduce the potential for auto-inoculation by preventing the wearer from touching their face. People wearing surgical masks often have to remove them to communicate with others around them; this is not necessary with face shields.
The use of a face shield is also a reminder to maintain social distancing, but allows visibility of facial expressions and lip movements for speech perception.
Face shields significantly reduce the amount of inhalation exposure to influenza virus, another droplet-spread respiratory virus.
In a simulation study with face shields , these were shown to reduce immediate viral exposure by 96% when worn by a simulated health care worker within 18 inches of a cough. Even after 30 minutes, the protective effect exceeded 80% and face shields blocked 68% of small particle aerosols,which are not thought to be a dominant mode of transmission of SARS-CoV-2.
When the study was repeated at the currently recommended physical distancing distance of 6 feet, face shields reduced inhaled virus by 92%, similar to distancing alone, which reinforces the importance of physical distancing in preventing viral respiratory infections.
