My 6 week old kitten has had like a couple tears, no sneezing, no lethargy, no wet nose, nothing like that.?

He hasn't been rubbing his eyes or anything. He is full of energy and appears to be fine I just have read that anything coming from their eyes can be bad so I was wondering what to do. I don't have money to take him to the vet so I want to know if this is normal or what to do. He also looks like he has fleas not to bad but could that cause the "tears"
