For starters, when we are awake, we blink. This helps remove excess mucus and irritants from the eyes. When we sleep, our eyes still continue to produce tears and mucus, but we aren’t blinking to remove these substances. This gives mucus the opportunity to collect in the corner of the eyes.
The good news is that this eye crust is normal and is rarely a cause for concern.
On the other hand, if you notice changes in your eye crust such as consistency, color, and quantity, this could signal a more serious problem. When the eyes tear excessively, it could be that they are attempting to keep themselves well lubricated to fight off infection.
One common condition that is represented by changes in eye crust is called blepharitis, or inflammation of the eyelid. Upon waking, you may notice that your eyelid is stuck together as a result of blepharitis. It’s important that you practice proper eye hygiene if you want to reduce your risk of blepharitis.
Other signs to pay attention to if you want to determine whether your eye crust is healthy is sensitivity to light, blurry vision, eye pain, swelling and redness, or fever.
