Do face shields

[I_UndergroundPanther]

Help protect against covid?

Will it help the mask protect you,or is it not useful?

Thinking of getting a face shield I got issues that put me at higher risk for Covid.

1. They protect your eyes. If someone coughs or sneezes you can catch it from your eyes. Plus

a little more protection from the area around the mask if you aren't wearing an N95

2. Yes, that is why people have been wearing them.

Thoses who work closely with people who are likely infected wear them to protect their eyes. Get a pair of cheap goggles for $10 if you don't want to wear one.

Doctors already said that protesters should be wearing them. People who fly on planes should wear them and educators who will be returning to work will wear them (in CA anyway).

3. I'll be wearing one in the fall, as well.

The reason educators need to wear them is less for protection, and more for disability access. (Masks are barriers to communication with students who rely on lip reading.)

4. The mask should be used with a face shield

Both for your protection and for the protection of others.

They serve two very different purposes.

5. I understand.

But students who need to lip-read cannot do so without specialized masks, so the standard for teaching will be face shield, alone

6. Just came across this about face shields

Face Shields and Containment of COVID-19

<snip>
The Infectious Diseases Society of America (IDSA) has included societal use of PPE, such as masks and face shields, in its recommendations for easing restrictions. Experience and evidence, even during this pandemic, suggest that health care workers rarely acquire infections during patient care when proper PPE is used and that most of their infections are acquired in the community where PPE is typically not worn. Thus, it becomes important to know if practice from occupational safety can be used in the community as a bridge to longer-lasting measures, such as vaccines. Could a simple and affordable face shield, if universally adopted, provide enough added protection when added to testing, contact tracing, and hand hygiene to reduce transmissibility below a critical threshold?

IMO worth a read
