The video explains the phenomenon of eye boogers, also known as gound or rheum, which are crusty residues that form in the corners of the eyes during sleep. These residues consist of mucus, dead skin cells, oil, dust, and bacteria. Eye boogers accumulate because the tear film, which usually clears debris when blinking, is less active during sleep. The video also discusses variations in eye boogers due to allergies or infections and reassures that they are generally harmless. It concludes with acknowledgments to patrons and encourages viewers to subscribe.
