Looks like pus to me.
If you have vet care, that would be best.
General care is to clean the eye with saline, press out the pus and apply an eye ointment 2-3 times a day. Terramycin eye ointment can be found at TSC. If the pus is stubborn, you may need to apply warm compresses to help...
Can you get some better photos of the eyes?
Has she had any symptoms of coughing, sneezing, mucous from the nostrils?
In the last photo, the eye looks it may have swelling due to pus. Possibly respiratory infection. Can you open the eye, flush it out and see if there's pus?
Sorry to hear...
