The eyes are a possible entry point for droplet transmission, so yes as it being part of other protections (mask, washing hands). Some have used/made face shields.

#103Quoting from the WHO/emergencies website[1] > If you are healthy, you only need to wear a mask if you are taking care of a person with suspected 2019-nCoV infection. The World Health Organization still recommends that you wear masks only if you're taking care of someone with COVID-19. Why is it so? Like if the evidence is so clear, why aren't they advising the general public about this? (PS. non-native english speake…
Maybe to prevent a rush on surgical masks so that they are kept for health workers who need them the most?
But then they could advertise using home made masks no?

While I agree, it wasn’t just general public opinion. In NYC at least, it was widely stated in the media by government officials and doctors that masks were unnecessary if you’re healthy, and actually could be bad because people were 1) removing surgical/n95 masks from supply, 2) wearing a cloth mask improperly sanitized can make you sick with other things. I like how Jeremy’s site has directly addressed those origin…
does it have to be n95 to prevent spread? my understanding was the n95 rating protects you from infected people where a plain old surgical mask protects others from you. In other words, the n95 mask has what it needs to prevent you inhaling the virus where a regular mask has what it needs to prevent a sneeze or cough from escaping to the people around you.
Can you explain how that could possibly be true?
A surgical mask is just a simpler cheaper, less complete and less effective mask than an N95 mask, used in lower risk situations or when N95 is desired but not available.

The WHO is, unfortunately, not a reliable source. They've repeatedly lied throughout the course of this pandemic. This is probably a well-intentioned one to preserve the global supply of masks, unlike previous lies which served only to make China look good, but the bottom line is that you shouldn't trust what they have to say.
CDC has said the same. Now people defend them saying they lied because they didn't want the public to hoard them but mask supply chains have been effected since probably January. I went to multiple Home Depots (upstate NY) end of February and they all told me they've been out of stock for more than a month. We couldn't hoard them even if we wanted to. Why even lie? It's pretty damn infuriating. Sk, HK, and Taiwan all have it under control because people there have been a lot more careful. They don't leave the house without a mask. Meanwhile in NYC, people were all casual about it up until maybe last week. Partly because of the delay in government response.

I myself have quoted the WHO and asked my friends not to wear them unless they're sick. Shouldnt have :(
Even in HN, until last week there were many articles linking to studies which said that surgical masks were not proven to reduce your chances of getting the virus.

From a recent episode of This Week in Virology[1]:
"Historically, in a lot of health care settings there was limited attention [to eye protection], and part of droplet protection, part of being protected when someone coughs or sneezes is protecting your eyes as well. Actually, going in to this I was pretty heavy on re-education at one of the hospitals about: if someone's on droplet, you gotta protect your eyes. Because influenza, you get that in your eyes you can get infected. SARS-CoV-2, you get that in your eyes you can end up with COVID-19. So eye protection is important as well."

#108Has the mask supply situation improved? I still see empty shelves for things like gloves, sanitizers, etc.
No. This calls on everyone to make their own. Lots of video tutorials, and some examples are dead simple (two rubber bands and a paper towel, if you have to).
> (two rubber bands and a paper towel, if you have to).
Two paper towels and a tissue paper actually.
The different materials lead to better filtration and absorption. The theory is to absorb the microscopic moisture that has COVID19 on it.

I think the "cut t-shirt" design is easiest. With a bit of sewing effort, you can make it 3-ply or 5-ply for additional protection. Try to get the grains to go in different directions.

Until the government bans masks in public places in the interest of, you know "public safety" once the covid-19 crisis blows over. It sucks that we even need to think about wearing masks to escape facial recognition.
"Until the government bans masks in public places in the interest of, you know "public safety"" The government did this long ago, as a reaction to the KKK wearing masks to intimidate their victims and hide their identity. So it's actually already against the law to wear masks in public in many places in the US. I've never heard of this law being enforced in modern times, however.
The situation is a lot more nuanced than that.
I challenge you to find an example of a blanket ban on all masks, that doesn't rely on other factors like threatening violence, rallying, intent to hide identity, or a respresenting specific gang design/color.

> Until the government bans masks in public places in the interest of, you know "public safety" once the covid-19 crisis blows over. That's overly fatalistic. China hasn't banned them for that reason, and they're way more interested in that rationale than any government you're likely talking about. > It sucks that we even need to think about wearing masks to escape facial recognition.

China has a comprehensive surveillance state that has fallbacks for cases when masks are not available.
