Put on your glasses – nerds unite – we had briefly mentioned this early in the pandemic – but now we have a study to confirm it – https://www.medrxiv.org/content/10.1101/2021.02.12.21249710v1

“Results In this study, total 58 patients showed the behavior of using spectacles continuously during day time and always on outdoor activities. The risk of COVID-19 was found 0.48 in spectacles wearing population as compared to 1.35 in population not using spectacles. The calculated risk ratio was 0.36. The protective effectiveness of the spectacles was found statistically significant (p-value .00113).

Conclusion The present study showed that the risk of Covid-19 was about 2-3 times less in spectacles wearing population than the population not wearing those. The nasolacrimal duct may be a route of virus transmission from conjunctival sac to the nasopharynx.”

Ouch the value of having manufacturing in your own country – sovereign risk is real when it matters – https://fortune.com/2021/02/22/covid-vaccine-india-serum-institute-supply-world-delay/

“The Serum Institute of India, one of the world’s largest vaccine makers, announced on Sunday that it would manufacture vaccines for India before doses earmarked for the rest of the world, a move that may delay vaccine shipments to dozens of countries and hamper the firm’s plans to share its vaccine supplies.

“Dear countries & governments,” Adar Poonawalla, the CEO of the Serum Institute, wrote on Twitter on Sunday. “I humbly request you to please be patient, [the Serum Institute of India] has been directed to prioritize the huge needs of India and along with that balance the needs of the rest of the world. We are trying our best.””
