There are several specific eye conditions that can result in abnormal eye discharge, leading to crusty eyes in the morning. While the manner in which crust forms is fairly intuitive, there may be some underlying health issues that can cause excessive discharge from the eyes or conditions in the skin that result in the accumulation of crust on the eyes. When sleeping, there is no opportunity to blink, and the combination of various substances like mucus, skin cells, dirt, and fluid within the eyes begin to compile within the corners of the eyes and dry to create the crust-like substance that many people commonly experience in the morning.The regular engagement in blinking protects the eye and also prevents liquid substances from drying, accumulating, and forming crust.Normally, blinking is a process that filters out potentially toxic substances from the eye.Morning crusty eyes form during sleep when the eyes are closed. When you are not blinking due to sleep, oil, mucus, aqueous humor (the fluid that lubricates the eye), skin cells, and dirt accumulate in these areas and dry, leaving a crust-like residue. A combination of liquids can accumulate during the night, making crusty eyes in the morning common and normal. Crusty eyes refer to the accumulation of discharge that dries on the lids and/or corners of the eyes.
