Blepharitis
What is Blepharitis ?
Blepharitis (blef-uh-RYE-tis) is inflammation of the eyelids. Blepharitis usually affects both eyes along the edges of the eyelids. Blepharitis commonly occurs when tiny oil glands near the base of the eyelashes become clogged, causing irritation and redness. Several diseases and conditions can cause blepharitis.
Blepharitis is often a chronic condition that’s difficult to treat. Blepharitis can be uncomfortable and unsightly. But it usually doesn’t cause permanent damage to your eyesight, and it’s not contagious.

Cause
The exact cause of blepharitis isn’t clear. It might be associated with one or more of the following. Seborrheic dermatitis — dandruff of the scalp and eyebrows. Infection. Clogged or malfunctioning oil glands in your eyelids. Rosacea — a skin condition characterized by facial redness. Allergies, including allergic reactions to eye medications, contact lens solutions or eye makeup. Eyelash mites or lice. Dry eyes.
Risk Factors
In addition to having rosacea and dandruff, you may be more at risk of developing blepharitis if you have diabetes. Wear contact lenses. Are exposed to irritants like dust and chemicals. Work or live in dry environments. This includes spending a lot of time in air conditioning. Have a high number of microbes that normally live on your skin. Don’t remove makeup thoroughly. Have oily skin. Are on certain drugs such as those for cancer treatment. Are going through menopause or hormonal changes.
When to see a Doctor
If you have blepharitis signs and symptoms that don’t seem to improve despite good hygiene — regular cleaning and care of the affected area — make an appointment with your doctor.
