Elbow + Eye = Lost Contact Lens

Weird and simple post...
As i went to work earlier, i got an elbow in my eye from a guy as while getting on the bus, which took out my contact lens. I could have searched for it but didnt bother; had to endure around 6 hours of having one eye working. I cut work early and went home by 10am, i slept the afternoon off. At least, I'm wearing disposable contacts, so replacing it wasnt much of a major prob. My eye seems to be ok, but still feels odd. Kind of itchy warm, feels like ive been rubbing my eye all day long...
