tteonttae

Tteonttae is a Korean term that refers to the waste material found accumulated in the corners of a person's eyes, particularly after waking up. It is a common and natural bodily occurrence. The substance is primarily composed of dried mucus, oil, and cellular debris that have collected on the surface of the eye. This accumulation happens during sleep when tear production and blinking are reduced, allowing these elements to gather.

The scientific term for tteonttae is rheum or sleep. It can vary in color and consistency depending on the individual and the specific circumstances. While generally harmless, excessive or unusual changes in the appearance of tteonttae, such as a sudden increase in amount, a change in color to green or yellow, or accompanying pain or blurred vision, could indicate an underlying eye infection or irritation and warrant medical attention. Otherwise, it is typically removed by gently wiping the eyes with a clean finger or a damp cloth.
