A study recently made massive, international news for reportedly showing that normal glasses may protect against COVID-19 Let's do a brief peer-review on twitter, because this is wild 1/npic.twitter.com/T94hRFvfXU

9/n (It's imperfect because not everyone who wears glasses is myopic and not everyone who is myopic wears glasses >8hrs per day)
10/n But then we hit the biggest snag of all The control population You see, the authors didn't actually collect a control sample. The rate of myopia here is from ANOTHER STUDY ENTIRELYpic.twitter.com/YH4f5BlDBK
11/n Not only that, but the study was conducted IN 1987 and the extrapolation is just weirdly moved forward from then This makes NO SENSE AT ALLpic.twitter.com/2RpQyPbyhY
12/n I honestly don't know what to say here. They're comparing the rate of myopia in a group of hospitalized patients with COVID-19 to the research findings of physical fitness of students from 1987 You can't draw any meaning from that!
13/n These two groups are so wildly different that it's entirely impossible to say whether the glasses had the slightest impact on anything at all, it's just very strange speculation
14/n Maybe glasses DO prevent COVID-19 transmission, but based on this research we have absolutely no idea if that's true
15/n The ABSOLUTE BEST you can say from this research is that it appears that fewer patients diagnosed with COVID-19 from a single hospital in Hubei had myopia than some high-school students in '87 It's not even about glasses!
