What Is Demodex and How Does It Affect Your Eyes?

If you’ve ever experienced persistent eye irritation, itchiness, or redness that doesn’t seem to go away, Demodex mites could be the culprit. These microscopic parasites naturally live on the skin, but when they overpopulate the eyelids and lashes, they can lead to inflammation and uncomfortable eye conditions.

Understanding Demodex Mites

Demodex mites are tiny organisms that inhabit the hair follicles and oil glands on your face, particularly around the eyelids and eyelashes. There are two main species that affect humans - Demodex folliculorum and Demodex brevis. In small numbers, they’re harmless. However, when their population increases, they can cause a condition known as Demodex blepharitis, which inflames the eyelids and affects overall eye comfort.

Common Symptoms of Demodex Infestation

Many patients mistake Demodex symptoms for allergies, dry eyes, or general irritation. Signs that you may have a Demodex overgrowth include:

•           Itchy or burning sensation around the eyes

•           Red, swollen, or crusty eyelids

•           Eyelash loss or misdirected lashes

•           Dry, irritated eyes that worsen in the morning

•           A sticky or gritty feeling in the eyes

If these symptoms sound familiar, it’s important to schedule an eye exam with a Philadelphia optometrist for a proper diagnosis.

How Demodex Affects Eye Health

When Demodex mites overpopulate the eyelash follicles, they feed on oils and dead skin cells, leading to blockages in the oil glands (meibomian glands). This disruption can worsen dry eye disease, cause chronic inflammation, and even increase the risk of eye infections if left untreated. Because these mites are difficult to see without magnification, many patients go undiagnosed for long periods, prolonging discomfort.
