1.Burning or Stinging
It’s often a sign of tired or irritated eyes, possibly from hay fever, dust, or smoke. It may also be a sign of blepharitis, a buildup of bacteria that causes dandruff-like flakes on your eyelids, or dry eye, when your eyes don’t make good-quality tears or enough of them. A more serious issue is an inflamed cornea, also known as keratitis.
2.Crust
When tears and oils dry, they can leave a sticky crust on your lids or lashes. A small amount when you wake up is normal, but you may need to see a doctor if you have more than usual, it’s yellow or greenish, or you have other symptoms, too. Pinkeye is contagious. Blocked tear ducts can lead to the buildup of tears and fluids on your eyes. Blepharitis can cause problems with your oil glands.
