yes a viral infection (cold) can cause a mild viral conjunctivitis (pink eye). since i can't really see or examine your child over the internet you will need to make the decision whether you feel she has eye redness due to a virus. or irritation. since she is really not having any other classic symptoms of pink eye like copious drainage or pain it would be prudent to just watch her for now. and make sure she doesn't rub her eyes.
is it pinkeye or not? . my 7 year old daughter has some white stringy goop the corner of her eye in the morning the last two days. she currently has a mild cold. also her eye is very slightly red. she says her eye does not hurt at all does not feel strange or scratchy no burning no itching. she was also playing out in the leaves a few days ago. wondering if it could have gotten irritated? does this sound like a mild pink eye or drainage from the cold? can a cold cause that type of drainage in one eye?
