Can Contacts Cause Blepharitis? Exploring the Link and Solutions
Can Contacts Cause Blepharitis? Yes, contact lenses can indirectly contribute to blepharitis by disrupting the natural tear film and potentially introducing bacteria or allergens, exacerbating existing conditions or triggering new cases. Proper lens care and hygiene are crucial to minimizing this risk.
Understanding Blepharitis
Blepharitis is an inflammation of the eyelids, typically affecting the part where the eyelashes grow. It’s a common condition, often chronic, and can be uncomfortable and unsightly. While not usually serious, it can lead to complications like dry eye, corneal ulcers, and styes. Understanding its causes and triggers is crucial for effective management.
The Tear Film and Contact Lens Disruption
A healthy tear film is essential for lubricating and protecting the eye’s surface. It consists of three layers:
- Lipid layer: This outer layer, produced by the meibomian glands (located in the eyelids), slows down tear evaporation.
- Aqueous layer: The middle layer, containing water, electrolytes, and nutrients, nourishes the cornea and conjunctiva.
- Mucin layer: The innermost layer allows the aqueous layer to spread evenly over the eye surface.
Contact lenses can disrupt this delicate tear film in several ways:
- Reduced tear volume: Lenses absorb tears, potentially leading to dry eye.
- Altered tear composition: The lens surface can attract tear components, changing the balance of the tear film.
- Blocked meibomian glands: Lens edge irritation can contribute to meibomian gland dysfunction (MGD), a major cause of blepharitis.
How Contacts Can Contribute to Blepharitis
While contacts don’t directly cause blepharitis in the sense of introducing a causative organism, they can significantly increase the risk or worsen existing symptoms. Here’s how:
- Bacterial buildup: Contacts can harbor bacteria, especially if not cleaned properly. These bacteria can then migrate to the eyelids and contribute to inflammation.
- Allergic reactions: Some individuals are allergic to contact lens materials or cleaning solutions, leading to allergic blepharitis.
- Reduced oxygen flow: Some older lens materials hinder oxygen flow to the cornea, potentially affecting the health of the surrounding tissues, including the eyelids.
- Increased rubbing: Dry eye associated with contact lens wear can lead to more eye rubbing, which can irritate the eyelids and exacerbate blepharitis.
Types of Blepharitis
Blepharitis is broadly classified into two main types:
- Anterior blepharitis: Affects the outside front edge of the eyelid, where the eyelashes are attached. Often caused by bacteria (like Staphylococcus) or seborrheic dermatitis (dandruff of the scalp and eyebrows).
- Posterior blepharitis: Affects the inner eyelid that touches the eyeball. Commonly associated with meibomian gland dysfunction (MGD).
Minimizing the Risk: Proper Lens Care and Hygiene
The key to preventing contact lens-related blepharitis lies in meticulous lens care and hygiene:
- Wash hands thoroughly before handling contact lenses.
- Clean lenses daily with the recommended cleaning solution. Rub and rinse the lenses as directed.
- Replace lenses according to the recommended schedule (daily, weekly, monthly).
- Use only fresh cleaning solution in the lens case. Never top off old solution.
- Replace the lens case regularly (every 1-3 months).
- Avoid wearing contacts while sleeping unless specifically prescribed by your eye doctor.
- Consider using daily disposable lenses to minimize bacterial buildup and protein deposits.
Treatment Options
If you develop blepharitis while wearing contacts, several treatment options are available:
- Warm compresses: Apply warm compresses to the eyelids for 5-10 minutes, several times a day, to loosen crusts and soften oils.
- Eyelid scrubs: Gently scrub the eyelids with a cotton swab or washcloth soaked in diluted baby shampoo or a commercially available eyelid cleanser.
- Artificial tears: Use lubricating eye drops to relieve dry eye symptoms.
- Antibiotics: In some cases, your doctor may prescribe antibiotic eye drops or ointment to treat bacterial infections.
- Oral medication: For severe or persistent blepharitis, oral antibiotics or anti-inflammatory medications may be necessary.
When to See a Doctor
Consult an eye doctor if you experience persistent symptoms of blepharitis, such as:
- Redness and swelling of the eyelids
- Itching or burning sensation in the eyes
- Crusting or scaling around the eyelashes
- Excessive tearing
- Sensitivity to light
- Blurred vision

Frequently Asked Questions
Can Contacts Cause Blepharitis by Spreading Bacteria?
Yes, improperly cleaned contact lenses can harbor bacteria that can contribute to blepharitis. Regularly cleaning and disinfecting your lenses as directed is essential to prevent this.
What Type of Contact Lens is Least Likely to Cause Blepharitis?
Daily disposable contact lenses are generally considered the least likely to contribute to blepharitis, as they eliminate the risk of bacterial buildup and protein deposits associated with reusable lenses.
What Are the Signs That My Blepharitis Is Related to Contact Lens Wear?
Symptoms that worsen with contact lens wear and improve when you remove your lenses suggest a connection. These may include increased redness, itching, and discharge when wearing contacts.
Can I Still Wear Contacts If I Have Blepharitis?
It depends on the severity of your blepharitis. Your eye doctor will advise whether it’s safe to continue wearing contacts and may recommend switching to a different type of lens or temporarily discontinuing wear until the condition improves.
What Are Some Contact Lens Cleaning Solution Ingredients That Can Irritate My Eyelids?
Some preservatives in contact lens solutions, such as thimerosal or benzalkonium chloride (BAK), can be irritating to sensitive eyes and may contribute to blepharitis. Consider switching to a preservative-free solution.
How Often Should I Clean My Eyelids If I Wear Contacts and Have Blepharitis?
Most eye doctors recommend cleaning your eyelids twice a day with a gentle eyelid cleanser or diluted baby shampoo, even when you are not wearing contact lenses. This helps remove debris and reduce inflammation.
Are There Any Specific Contact Lens Materials That Are Better for People Prone to Blepharitis?
Silicone hydrogel lenses are often recommended as they allow for better oxygen permeability compared to traditional hydrogel lenses, which may reduce dryness and irritation.
Can Dry Eye Caused by Contact Lens Wear Worsen Blepharitis Symptoms?
Yes, dry eye is a significant contributing factor to blepharitis symptoms. When your eyes are dry, they are more susceptible to irritation and inflammation, which can exacerbate blepharitis.
What Are the Long-Term Risks of Ignoring Blepharitis While Wearing Contacts?
Ignoring blepharitis can lead to chronic inflammation, corneal ulcers, scarring, and vision impairment. It’s crucial to seek treatment and manage the condition effectively.
Should I Change My Contact Lens Solution If I Develop Blepharitis?
Yes, switching to a preservative-free contact lens solution is highly recommended. The preservatives in some solutions can irritate the eyes and worsen blepharitis symptoms.
Can Allergies to Contact Lenses Cause Blepharitis Symptoms?
Yes, allergic reactions to contact lens materials or cleaning solutions can manifest as blepharitis symptoms, such as redness, itching, and swelling of the eyelids. If you suspect an allergy, consult your eye doctor.
What Foods Should I Avoid to Prevent Blepharitis While Wearing Contacts?
While diet is not a direct cause, some studies suggest that a diet high in processed foods and refined sugars may contribute to inflammation in the body, potentially exacerbating blepharitis. A diet rich in omega-3 fatty acids may be beneficial.
