Totally insane!
Unless you’re talking about those ppl who wear sunglasses indoors
or in the winter.(not for medical reasons)… see above.
I hear that sneezing in public, especially if you are blessed with a hearty sneeze is a big no no as far as Tznius, Its draws major attention as does screaming for help while being mugged.
Yup! Totally Assur for a jewish woman to shout help or chaptzem,
while bein mugged or in danger.
Studies have shown that shouting in public draws attention to oneself, almost as much as wearing sunglasses.
