What Are Demodex Eyelash Mites?
Demodex are tiny mites found in or near hair follicles. They are most commonly found on the face and around the eyelashes, and they feed on the skin cells, bacteria, and oil there. They're usually about 0.3 mm long, have eight legs, and their body is covered in scales for anchoring into a hair follicle. Feeling itchy yet?!
Infestation is very common, especially in the elderly and immunocompromised people, and usually does not cause symptoms, but eye issues such as blepharitis, dry eyes, and meibomian gland dysfunction can be exacerbated.
