Let that be a lesson to you all to not get Euphorbia sap in your eye. Don’t get it on your hands and if you do wash your hands thoroughly and immediately. Don’t wait ’til later because you will have forgotten long enough to touch your eye and then look at what happens.
By the way, don’t touch your lips either.
In the meantime, here’s a Euphorbia picture.
