Tears are fairly normal but when you have an abnormal discharge like mucus coming out of your eyes, it may be time to visit your optometrist for an examination. Excessive eye discharge can be a sign of a bigger underlying problem. For the most part, these eye “crusts” can be removed by washing your face or rubbing them away, but this is not recommended. In the worst cases, your eyes may even be forced shut by dried up mucus. When this happens, it’s always best to consult with an eye care specialist.
