I threw a cookie in the air,caught it with my mouth,then a little crumb went in my eye.
What do I do?
Do I do anything or will it dissolve or something?
Get some eye drops and constantly flush your eye with the solution. This won't dissolve it but it might flood your eye enough to bring to the surface and eventually out of your eye. Don't use water cause this will dry out your eye and cause more irritation.
Your tears should wash it out to teh corner of the eye eventually. If its scratched yoru eye you might feel it for a while after its gone. Other thing I sometimes use ( but not if i have lenses in ) is to pull my top lid over the bottom lid and the eyelashes tend to push it out. Eye drops might wash it out faster as well.
