Sure those work just make sure their only sodium chloride 0.9% with nothing else in them, i dont know much about contact solutions, and I know some eye drops have other things added to them like visine has what 5+ different formulas now?
If you had first aid eye flush thats easier to use more of then expensive contact solutions and such and you can be much more generous with it, I usually just fill a 3ml syringe and give the eye a good flush from 1 corner to the other in a nice stream, faster then a single drop but still gentle, but then again I get the 1000ml IV bags to use for this. With the drops you only need about 2, just make sure it gets under the eyelids to get any bits of anything out, wait an hour or so, then do another 2 or so drops to make sure everythings all washed out, then repeat in the morning.
Are you able to get a picture of the eye? So we can see the colour of the weepys? What colour is her sclera? Is it bloodshot, solid red, at all irritated looking?
do you notice any abnormalities on the lense?
From certain angles you may be able to tell if there are any scratches on the surface of the eye.
is the eyeball itself leaking from anywhere?
Do you have a small flashlight (a dull one) that you can shine in her eye (from the side, please do not shine the light directly into her eye) just let us know as much as you can, the more we know the more we can help you rule out before we jump to infections, especially if its just some clear fluid. Hopefully its just an irritant and flushing it out will work, if not at least it will feel better.
