The odds of transmission are slight IF the person has HCV, HBV, HAV. I don't think you'll find many (or any) documented cases.
Of course, IF the person has none of those viruses it is IMPOSSIBLE.
IF a person had any of those viruses I don't believe the symptoms would manifest in the eye, much less after a few hours.
It looks as though a person is obsessing about an occurrence and the mind is creating symptoms......that an uninformed person suspects would manifest if exposed to hep A, B, or C.
I have seen no claims of transmission from spit in the eye.
I think a "great" answer would be to suggest that the transmission odds are slim to none. I'm afraid that providing a link stating there is Hep B DNA presence in tears of infected people only tells half the story and promotes needless fear and hysteria.
Whats next? Infection from handshakes?

It looks like more hysteria from here......
(and it serves to distract us from the worldwide avian...... oops, I mean swine flu pandemic) ; )
