Ever wondered what the white crusted dust or mucus at the corner of your eye is every morning? Whether you call it eye-gound, gunk, mucous or eye-booger, this discharge is healthy. It is a way of eliminating waste or harmful debris from the surface of your eyes or the tear film. Dr Sanjay Verma HOD of Ophthalmology, Paras Hospitals, Gurgaon answers our queries related to sleep dust or eye mucous

What eye mucous? How and why is it produced?

It is a combination of the oil, dust and skin cells which form a sticky or crusted dust that accumulates in the corner of your eyes. Our eyes produce tears throughout the day, but sometimes this tear film is reduced due to various reasons and the normal day to day pollutants are not washed out from the eye because of this. The mixture of moisture with these pollutants is mucus. When we are asleep, we don t blink. Since we don t blink, eye discharge collects in the corners of our eyes throughout the night, resulting in us waking up with that familiar crusty mucous in our eyes.
