Do face shields work for Covid 19?
There is still some debate on whether or not face shields provide adequate protection against Covid 19, but many experts believe that they are effective in preventing the spread of the virus. Face shields work by creating a barrier between the person wearing them and the outside world, which can help to protect the wearer from respiratory droplets that may contain the virus. In addition, face shields can also help to protect other people from the wearer, if the shield is worn properly and covers the mouth and nose.

What keeps a face shield from fogging up?
A face shield is typically made of clear plastic and is intended to protect the wearer’s face from debris, flying objects, and other potential hazards. One of the main problems with wearing a face shield is that it can fog up, making it difficult to see. There are a few things that can be done to prevent this from happening.
One way to keep a face shield from fogging up is to apply a small amount of baby powder or anti-fog spray to the inside of the shield before putting it on. Another way to prevent fogging is to make sure that the shield is properly positioned on the head so that there is no gap between the shield and the forehead.
Another potential cause of fogging is the temperature difference between the inside of the shield and the outside environment. When the temperature inside the shield is warmer than the outside air, moisture can condense on the inside of the shield, causing it to fog up. To prevent this, try to keep the temperature inside the shield as close to the outside temperature as possible.
If the face shield does fog up, there are a few things that can be done to clear it. One is to simply take the shield off and wipe the fog away with a cloth. Another way is to use a hairdryer on the low setting to blow the fog away.
What are the disadvantages of face shields?
There are a few disadvantages of face shields that should be considered before using one as a primary or sole form of protection against COVID-19. Face shields may fog up, which can limit visibility, and they also leave the mouth and nose exposed, which may increase the risk of infection if the wearer is not wearing a mask as well. Additionally, face shields may not provide as much protection against COVID-19 as masks, since the virus can still enter through the sides of the shield.

This is because face shields provide additional protection by covering your entire face and helping to prevent contact with hazardous materials.
Both masks and face shields have some drawbacks. Masks can make it difficult to breathe and can cause you to feel claustrophobic. Face shields can fog up, making it difficult to see.
