What Causes Redness Around The Eyes Of A 14 Month Old?

Hi there, I have a 14 month old little girl and about a week ago we started noticing some redness around the inner outside of both of her eyes. The eye iteself is white with no redness, no puss or discharge and she is not rubbing them at all which leads me to believe they aren t bothering her. Just wondering if this may be a clogged tear duct? There is also a small bit of swolleness under each eye as well. No change in diet, atmosphere, soaps etc, no medical history of anything. She woke up this morning will a runny nose which is different than yesterday. thanks for any help.
