Pain in eyes

Not sure if this is postpartum related because i only got it recently. but when I wake up to Use the bathroom or even to make my daughter milk I get the worst pain/burn in my eyes it only happens when I’m extremely tired according to google is called a eye strain and is so painful it feels like I have 10 eyelashes in my eye and it last about 5 minutes or so. Anybody know any recommendations I never had this before but then again this is my first year forcing my eyes to wake up to make bottles (first kid)
