Blepharitis: Causes, Symptoms, Diagnosis, and Effective Management
A detailed guide to understanding blepharitis, its symptoms, causes, and practical strategies for lifelong management and eye health.
What Is Blepharitis?
Blepharitis is a chronic inflammatory condition affecting the eyelids, particularly the eyelid margins where the eyelashes grow. It can occur in people of all ages and is often persistent, frequently requiring ongoing management to control its symptoms. Blepharitis is not contagious and is not caused by poor hygiene. Understanding its causes, symptoms, and management strategies is crucial for maintaining eye health and preventing complications.
Types of Blepharitis
- Anterior Blepharitis: Affects the outer part of the eyelid where the eyelashes attach. Commonly caused by bacteria or skin conditions like dandruff.
- Posterior Blepharitis: Involves inflammation of the inner eyelid margins, often related to malfunctioning oil glands (Meibomian glands), which may be associated with skin conditions such as rosacea.
- Acute Blepharitis: Usually develops suddenly and may resolve with treatment.
- Chronic Blepharitis: The most common form, it is persistent and tends to recur, necessitating regular care and attention.
Core Causes of Blepharitis
| Cause | Description |
|---|---|
| Bacterial Infections | Most commonly Staphylococcus, affects the base of eyelashes or glands. |
| Demodex Mite Infestation | Microscopic mites occasionally found on lashes, especially in chronic cases. |
| Blocked Oil Glands | Dysfunction of Meibomian glands may cause oily buildup and inflammation. |
| Skin Conditions | Rosacea, seborrheic dermatitis, and dandruff are commonly associated conditions. |
| Allergic Reactions | Irritation from makeup, eye drops, or environmental allergens. |
| Viral Infections | Occasionally herpes simplex or other viral agents. |
Recognizing Symptoms of Blepharitis
- Red, swollen eyelids
- Itching, burning, or stinging sensation in and around the eyes
- Greasy or sticky eyelid margins
- Crusty or scaly skin forming at the base of the eyelashes
- Tearing (watery eyes)
- Flaking or matting of the eyelashes
- Sensitivity to light
- Foreign body sensation (feeling like there’s something in the eye)
- Loss or abnormal growth of eyelashes
- Dry, gritty, or sandy feeling
Symptoms can range from mild to severe, often fluctuating over time. Chronic blepharitis may lead to persistent discomfort, especially in the morning due to overnight buildup of scales and crusts.
How Is Blepharitis Diagnosed?
Diagnosis is primarily clinical, based on a detailed eye examination. Key steps include:
- Assessment of symptoms and medical history
- Examination of eyelids with a magnifier or slit lamp to check for redness, scaling, abnormal lash growth, and oil gland function
- Sometimes, swabbing the eyelid for laboratory testing to identify bacteria, mites, or other underlying organisms
- If symptoms do not improve or only affect one eye, additional testing for underlying skin disorders or rare conditions such as eyelid cancer may be considered
In most cases, diagnosis is straightforward. However, persistent symptoms may prompt referral to an ophthalmologist for specialist assessment.
Treatment and Management of Blepharitis
Blepharitis is not curable but is usually manageable with consistent self-care and, when indicated, prescription treatments.
Self-care Measures
- Daily Eyelid Hygiene: Gentle cleansing of the eyelid margins with diluted baby shampoo or recommended eyelid wipes
- Warm Compresses: Applying a warm, damp cloth for several minutes to loosen crusts and improve comfort
- Lid Massage: Gently massaging the eyelid can help express clogged Meibomian glands and reduce inflammation
- Avoid eye makeup during active flare-ups; discontinue use if symptoms worsen
- Use artificial tears if dryness is present

Medical Treatments
- Antibiotics: Topical ointments (erythromycin, bacitracin), drops, or oral medication for bacterial infection or inflammation
- Anti-inflammatory medications: Short-term use of steroid eye drops or ointments to control severe inflammation
- Immunomodulatory drugs: Ophthalmic cyclosporine (Restasis) for inflammation, especially in posterior blepharitis
- Advanced Procedures:
- BlephEx (lid margin debridement): Professional cleaning to remove bacteria, mites, and their biofilm
- Lipiflow (thermal pulsation): Melts blockages in Meibomian glands
- Intense Pulsed Light (IPL): Opens clogged glands, reduces inflammation
Treatment for Underlying Conditions
- Control of associated skin conditions (rosacea, seborrheic dermatitis) with appropriate creams, oral medications, or lifestyle modifications
- Treatment for dry eye with artificial tears or eye drops as indicated
Potential Complications of Untreated Blepharitis
- Recurrent stye or chalazion (blocked, inflamed gland)
- Conjunctivitis (secondary infection of the eye lining)
- Eyelash loss, misdirection, or abnormal growth
- Corneal damage: Chronic inflammation may injure the cornea, leading to ulcers or scarring
- Impaired vision (rare)
- Chronic discomfort and self-consciousness
Who Is at Risk for Blepharitis?
- Individuals with rosacea or seborrheic dermatitis
- People prone to skin allergies
- Those who wear contact lenses (due to higher risk of surface irritation)
- Individuals with a history of recurrent eye infections
- Aging, since gland dysfunction is more common in older adults
Some risk factors like skin conditions and age are not modifiable, but proper eyelid hygiene can reduce the risk and severity of flare-ups.
Prevention: Daily Habits for Healthy Eyelids
While not all cases are preventable, effective strategies can help:
- Practice daily eyelid cleaning as recommended
- Manage skin conditions with regular dermatological care
- Limit use of eye makeup and replace products regularly
- Use preservative-free artificial tears to combat dryness
- Avoid touching or rubbing eyes with unwashed hands
- Replace contact lenses at recommended intervals and follow cleaning instructions
- Seek prompt care for persistent eye redness, discomfort, or visual changes
Frequently Asked Questions (FAQs)
Q: Is blepharitis contagious?
No, blepharitis is not contagious. It results from chronic inflammation or bacterial colonization, not person-to-person transmission.
Q: Can blepharitis be cured?
Blepharitis cannot be cured, but most cases can be controlled with consistent management, including eyelid hygiene and appropriate medical treatment.
Q: Will poor hygiene cause blepharitis?
Poor hygiene is not a root cause. The condition has more to do with bacterial or glandular issues and underlying skin conditions.
Q: Can I still wear makeup if I have blepharitis?
Avoid makeup during active flare-ups. Once symptoms are controlled, cautiously resume, using hypoallergenic products if possible. Old makeup should be discarded to prevent reinfection.
Q: When should I see a doctor?
Consult your doctor if symptoms persist after a few days of self-care, if you develop visual changes, or have severe pain or discharge. Persistent or worsening symptoms may need medical or specialist evaluation.
Tips for Lifelong Management
- Make eyelid hygiene part of your daily routine — consistency matters
- Maintain awareness of triggers or flare-up patterns (such as seasonal allergies or skin condition exacerbations)
- Attend regular follow-up visits if recommended for chronic cases
- Inform your eye care provider about any associated skin or eye conditions
- Keep informed about new treatment advances; procedures like BlephEx and Lipiflow may be recommended in select cases
- Educate family members, especially if skin conditions like rosacea or eczema run in your family

Yes, blepharitis affects all age groups, including children and older adults. Chronic adult blepharitis is most common, but children may also be affected by bacterial or allergic causes.
Is regular eye care necessary for blepharitis?
Yes. Regular eyelid cleaning, prompt treatment of skin conditions, and eye health check-ups are important for lifelong management and prevention of complications.
What should I avoid if I have blepharitis?
Avoid touching or rubbing eyes, skipping eyelid hygiene routines, sharing eye makeup, and using makeup during flare-ups. Protect your eyes from irritants and allergens where possible.
Conclusion
Blepharitis is a common chronic eye condition characterized by inflammation of the eyelids, often complicated by bacterial colonization, glandular malfunction, or associated skin disorders. While it cannot be cured, daily eyelid hygiene and appropriate medical therapies enable most people to manage symptoms effectively and maintain eye comfort. Consult your doctor if you have persistent discomfort, reduced vision, or worsening symptoms, as timely intervention helps protect your long-term eye health.
