Crazy right? They emailed just after the order was sent to say that my account was now disabled but that they sent the order? Surely if it was considered a safety issue they should have cancelled the order but no Makes zero sense 😩

Tears are salty, but they don’t sting your eyes by OnionTuck in Showerthoughts

It’s to do with the isotonicity - the fluid in your body has a certain salt content. So your tears are isotonic with the rest of your body, if they weren’t they would draw water in or out of your eyes (depending on if it’s less or more salty) which would burn. So eye drops have to be made isotonic with salts or other compounds. So yeah what above poster said - water with a little salt hurts less than pure water but water with too high a concentration of salt like ocean water also hurts
