Watery sticky eyes

I read that 1 in 5 newborns tear ducts aren't fully developed and that causes them to have watery sticky eyes. I believe my son is dealing with this, and I was just curious if anyone else suspects the same with your LO? I'm going to ask the pediatrician just to rule out a possible allergy. The whites of his eyes are still white and not red which doesn't make me think it's an allergy,
