Baby constantly running her eyes

Gennifer

So lately I noticed when my baby is tired she will rub her eyes so I took that as a sign that she is ready for a nap. Then recently I noticed she does it all day long?? Sometimes she does it so much while trying to sleep it makes her eye puffy. Anyone know why this might happen? She had a doctors appointment last week and her vision was fine. Is this just she will eventually stop doing?
