Face shields are more effective than masks at preventing exchange of droplets.(1) They can be cleaned and reused so it may save money and material for the general public to popularize face shields.
1. "There may be some protection from droplets and liquids propelled directly onto the mask, but a faceshield would be a better choice if this is a concern." https://www.cidrap.umn.edu/news-perspective/2020/04/commentary-masks-all-covid-19-not-based-sound-data https://www.cidrap.umn.edu/news-perspective/2020/04/commenta...
- dx87 7y agoRight, but staying home is even more effective at preventing exchange of droplets. The face shields should be going to people who can't stay home and are forced to be around contagious people.
- jacksnipe 7y agoA huge number of Americans cannot stay home and are not healthcare workers. People have bills to pay, and not every non-healthcare business is closed, unfortunately.
- kojeovo 7y agoRight but that still doesn't seem like a good enough reason for Apple to start selling these publicly.
- zaroth 7y agoWhy unfortunately? I'd say it's quite fortunate that grocery stores and gas stations are still operational.
- samename 7y agoIt's unfortunate because these people are having to put their lives at risk, unexpectedly. They didn't ask to be on the frontlines. In addition, many of them haven't been able to get hazard pay or adequate sick pay.
- munk-a 7y agoAnd some of them (especially within those fields) may be forced by their employer to work part-time and not be eligible for employer sponsored health insurance.
- vkou 7y ago> Right, but staying home is even more effective at preventing exchange of droplets. There are tens of millions of Americans who are currently working, who cannot stay home, and are not medical professionals.
- sailfast 7y agoI’d like to leave my house in a month or two. You?
- brodie 7y agoYou’re allowed to leave your house. Exercise, pet walking, and essential shopping and other essential activities aren’t banned. Put on a mask and go for a walk in your neighborhood and keep social distancing.
- sailfast 7y agoRight - this is obviously what I would do. However, if face shields were helpful for reducing risks for general interaction (no idea if they are) then I’d also want one. The fastest path to leaving the house is reducing the risk of leaving, so some simple PPE (that is more effective than a mask) would be great.
- aledalgrande 7y agoMasks are more effective at preventing spread from untested, asymptomatic infected people though.
- mbreese 7y agoThat isn't what that sentence means... Think of it like a squirt gun. If someone is spraying a squirt gun at you, a mask will protect you a bit, but it eventually will be saturated and you'll be wet. However, if you have a face shield, the water will just roll off. Masks are better at protecting you from small particles. Using a face shield without a mask would do you absolutely no good when you're trying to protect yourself from an airborne pathogen or micro-droplets. When you breathe, you're going to draw in air from around the sides of the shield. If you have a mask (N95), then you're breathing air in through the filtering fibers of the mask. This is what protects you. Masks and face shields have two very different purposes.
