Ask an Eye Doctor and Get an Answer ASAP
Hi. I'm online and happy to answer your question today.
That is a very good question. Could you tell me a bit more about what specifically happened? Also, were you wearing contact lenses at the time?
In one instance, if someone's hands were not washed after a bowel movement, and in another instance, if someone touched a surface that had bird or animal droppings, or had come in contact with them
Thank for you for that information. In both of the situations you are asking about the risk of getting an eye infection would be very, very low.
The tear film contains antibodies to fight organisms/bacteria. The lids and tear film rapidly remove any foreign material and bacteria and the corneal epithelium is a strong physical barrier to infection.
I do not think that you would have any need to worry about an eye infection in either of the scenarios you described.
Does this make sense to you?
Thanks. I'd thought such bacteria would be quite severe.
No. They are no match for your eyes defenses :-)
Have a Happy Holidays

lysozyme is a enzyme in tear film that destroys components of bacteria and other critters.
What if fecal matter or animal droppings were indeed to actually get into one's eyes by accident?
And what about raw fish from sushi - would that contain parasites or bacteria that could cause harm if accidentally rubbed into eyes?
