Is your vet open today? I'd get her in ASAP. This could be debris implanted in the eye or a corneal scratch - which is extremely painful. Normal eye infections involve some redness, goopiness, discharge, even some smelliness. BUT, when a dog is trying to keep it's eye closed due to discomfort - I'd err on the side of getting her in ASAP - bc not only could you be risking terrible damage - but eye pain can be excruciating. Hopefully, it's nothing - but normally (normally), dogs don't squint or try to keep their eyes closed with just a bacterial infection.
I've personally had a corneal scratch and it is nearly unbearable, without medication.
