Input: Text: this happened a while ago but thought it was worth mentioning now i've found this sub. i went to brush my teeth before bed with what turned out to be new toothpaste with a menthol kick and "micro cleaning beads". these two details are important. when applying said toothpaste to the brush it turns out that i give the brush a little flick to end the flow of toothpaste. this little flick was my undoing. some remnant of the toothpaste was flicked upwards connecting perfectly with my eyeball. 

evolution's good sense to make the human eye snap shut when something comes into contact with it was my second undoing. the aforementioned menthol and mint was like an acid on my eye. the micro beads started exfoliating my pupil as i blinked desperately over the sink trying to flush my stinging eyeball. i was a blinded mess. it hurt to blink because of the beads but it hurt to open my eye because of the menthol. 

it took about ten minutes to regain my vision and it felt like i had sand in my eye for at least 24 hours. that careless flick of the toothbrush caused enough discomfort to ensure i take all appropriate precautions when brushing my teeth now.
