That happens to me all the time. I have to close my eyes tightly when I blow my nose to stop snot bubbling out of the right one.
I was sniffing from a tin lid and as I brought the lid up to my nose I coughed, got a whole hit right in the eyeball, I was blind for a good half hour, best vitimin N rush I’ve ever had though
A week or so ago I had some snuff bounce off of my hankie and fly into my eye. It was burning and watering like crazy and I made the stupid mistake of wiping it with my snuff hankie. After a day or two of waking up with my eye sealed shut, I ended up getting pink eye, first time I have ever had it in my life. I am thinking it was not a good idea to try and wipe my eye with my well used hankie. Lesson Learned… Keep my eyes closed when blowing snuff out of my nose and don’t use hankie to wipe my eye!
When I am riding a bus and the window is open and I will take a pinch , sometimes some snuff flies and go to my eyes, it hurts a lot .
I did this once while doing some weeding. The wind picked up and end up blowing a gram of snuff directly into my left eye. I learned from that experience take a pinch with proper shelter when it is windy and you are in an outdoor environment.
