Coffee And Blepharitis

Have you ever woken up to puffy, irritated eyes, complete with crusty eyelashes and red, swollen eyelids? Or maybe your eyes burn, itch, or water constantly, especially first thing in the morning. If this sounds familiar, you could be dealing with a common condition called blepharitis.

What is Blepharitis?

Blepharitis causes inflammation along the edges of the eyelids. The condition affects about 3-6% of the population, so if you have it, you’re definitely not alone!

The term blepharitis comes from the Greek words for eyelid (blepharon) and inflammation (itis). It commonly affects both eyes, causing irritation, redness, burning, and dryness.

There are two main types of blepharitis:

Anterior Blepharitis

This type occurs along the outside front of the eyelids, where the eyelashes meet the lid. Dandruff and oil from the scalp can collect here, causing inflammation fueled by bacteria. Demodex mites that live in eyelash follicles can also contribute to anterior blepharitis.

Posterior Blepharitis

Also called meibomian gland dysfunction (MGD), posterior blepharitis affects the inner eyelids. It happens when oil glands inside the lids called meibomian glands become clogged, leading to reduced oil secretion. This disrupts the tear film and allows rapid evaporation of tears from the eye’s surface.

No matter where it occurs, blepharitis can cause annoying symptoms like:

  • Red, swollen, itchy eyelids
  • Burning or stinging eyes
  • Excess tearing, watery eyes
  • blurred vision
  • Light sensitivity
  • Eye fatigue or heaviness
  • Crusting along the lashes
  • Flaky skin along the lids

Left untreated, blepharitis can result in dysfunction of the oil glands, corneal damage, and even vision loss in severe cases. So getting prompt treatment is important for protecting long-term eye health.

Can drinking coffee worsen symptoms of blepharitis?

Many people with blepharitis wonder if drinking coffee can worsen symptoms. Studies have shown that caffeine can exacerbate dry eye, which is a common symptom of blepharitis. If you have green vs red dot astigmatism, it’s important to be mindful of your caffeine intake and how it may impact your eye health.

Coffee and Blepharitis: What Does the Research Say?

If you’re a coffee lover struggling with blepharitis symptoms, you may wonder: Could my precious morning brew be to blame?

Over the years, some research has suggested that components in coffee may worsen blepharitis, especially the posterior/MGD form of the condition.

The main suspect has been caffeine. As a stimulant, caffeine could potentially cause issues like:

  • Increased tear evaporation due to widened eyes/eyelid retraction
  • More frequent blinking
  • Eye twitching or spasms
  • Dehydration and reduced tear production due to its diuretic effects

However, the evidence linking caffeine consumption to worse blepharitis is still weak. Most studies have depended on self-reported data or been based on very small sample sizes.

For example, a 2019 review found only anecdotal reports of caffeine worsening meibomian gland dysfunction. But the researchers admitted they need larger, more rigorous studies to truly determine caffeine’s impact on dry eye.

Other recent research suggests caffeine could even improve blepharitis symptoms:

  • A 2017 study found caffeine consumption significantly increased tear production.
  • Another trial in Ophthalmology showed caffeine led to improved tear film stability.

The conflicting results demonstrate we need more high-quality clinical trials to understand caffeine’s effects on blepharitis and dry eye disease. There’s simply not enough evidence yet to directly link coffee intake to worse blepharitis.

Possible Links Between Coffee and Blepharitis Symptoms

Despite the lack of clear evidence, there are some plausible ways coffee could potentially impact blepharitis:

Coffee as a Diuretic

The caffeine in coffee is a mild diuretic, meaning it makes you urinate more frequently. This modest increase in urine output could theoretically make eyes drier. However, for most people drinking moderate amounts of coffee, dehydration is unlikely to be a major issue.

Exacerbating Underlying Conditions

Blepharitis often goes hand-in-hand with rosacea, a chronic skin condition characterized by facial redness. Coffee and caffeine are common rosacea triggers. So if you have underlying rosacea, coffee may indirectly worsen blepharitis by flaring up this condition.

Interacting with Medications

Caffeine could potentially interact with certain medications used to treat blepharitis symptoms, like antibiotic and steroid eye drops. Ask your ophthalmologist about possible interactions if you take other medications along with coffee.

On the flip side, coffee may benefit blepharitis in some ways:

Anti-Inflammatory Effects

Coffee contains antioxidants and polyphenols that appear to have anti-inflammatory properties. By reducing inflammation, coffee could theoretically improve irritated, swollen eyelids caused by blepharitis.

Stimulating Tear Production

As mentioned earlier, some research indicates caffeine may directly stimulate tear secretion. More tears could relieve the dryness and irritation of blepharitis.

Overall the links between coffee and blepharitis remain uncertain. If you have symptoms, limiting caffeine intake is reasonable. But you don’t necessarily have to cut out coffee completely.

Lifestyle Changes and Treatments for Blepharitis

While the jury is out on coffee, other lifestyle measures and medical treatments can definitely help manage blepharitis.

Eyelid Hygiene

Keep your eyelids clean by gently scrubbing with a mild, unscented cleanser like baby shampoo. Using warm compresses before scrubbing can help soften and loosen debris.

Artificial Tears

Over-the-counter lubricating eye drops like artificial tears help supplement your natural tears. They provide moisture and relieve dryness, stinging, and burning.

Antibiotics and Steroid Treatments

For anterior blepharitis, antibiotic ointments combat bacteria along the lash line. Steroid eye drops can reduce swelling and inflammation.

Managing Underlying Conditions

Controlling flares of rosacea, seborrheic dermatitis, and other related conditions helps minimize blepharitis symptoms. Your dermatologist can recommend treatments.


Some research suggests omega-3 fatty acid supplements may improve meibomian gland function and tear production. Boost your omega-3s by eating fish or taking supplements.

When to See a Doctor

See an ophthalmologist promptly if you experience:

  • Persistent discomfort, pain, irritation
  • Significantly blurred or reduced vision
  • Recurrent styes
  • Corneal damage
  • Vision loss

Early treatment helps prevent blepharitis from seriously impacting your vision and eye health.

The science is still fuzzy when it comes to pinning down caffeine’s exact effects on blepharitis. Your morning coffee ritual doesn’t have to end if you develop problematic eyelid inflammation. But moderating intake, staying hydrated, and using lubricating drops might provide some relief, especially if you have posterior meibomian gland dysfunction.

Pay attention to your own symptoms and avoid triggers that seem to worsen your blepharitis. And don’t hesitate to see an ophthalmologist if you have any vision changes, severe discomfort, or concerns about your eye health. With a combination of good eyelid care and certain medical treatments, most cases of blepharitis can be managed effectively.
