While lid hygiene handles the external symptoms, true long-term management of blepharitis often requires looking at your systemic health. Your eyes are part of your body, and inflammation is rarely isolated.

The Anti-Inflammatory Diet

Systemic inflammation exacerbates blepharitis. An anti-inflammatory diet can help regulate the body's immune response.

  • Eat: Leafy greens, berries, fatty fish, nuts, and olive oil.
  • Avoid: Processed sugars, excessive alcohol, and high-omega-6 vegetable oils (which can be pro-inflammatory if not balanced with omega-3s).

Omega-3 for MGD

This is the single most evidence-backed supplement for Meibomian Gland Dysfunction (MGD). Omega-3s help change the composition of the oil in your eyelid glands, making it more fluid and less likely to clog.

"Consistency is key. It typically takes 6 to 12 weeks of daily supplementation to notice a change in oil quality."

Aim for a high-quality fish oil or algae oil supplement containing at least 2000mg of combined EPA and DHA daily.

Blinking exercises for MGD (20-20-20 rule)

When we stare at digital screens, our blink rate drops by up to 60%. Worse, we often do "partial blinks" where the lids don't fully touch. This prevents the meibomian glands from releasing oil.

Try this exercise: Every 20 minutes, look 20 feet away for 20 seconds. During this break, perform 5 hard, complete blinks. Squeeze your eyes shut intentionally to force oil secretion.

Hydration and Environment

Dehydration reduces the water volume of the tear film, making it saltier (hyperosmolar), which triggers inflammation.

  • Drink Water: Aim for adequate daily intake.
  • Humidify: In winter or air-conditioned offices, use a humidifier to prevent tear evaporation.
  • Sleep Mask: If you sleep with your eyes slightly open (nocturnal lagophthalmos), use a moisture-chamber goggle or sleep mask to seal in humidity overnight.

FAQs

Can diet help blepharitis?

An anti-inflammatory diet can support eye health and may reduce flare-ups.

Do omega-3 supplements help MGD?

They can improve oil quality for some people, but it usually takes weeks of consistent use.

Does screen time make blepharitis worse?

Yes. Staring at screens reduces blink rate and worsens gland blockage.

What is the 20-20-20 rule for dry eye?

Every 20 minutes, look 20 feet away for 20 seconds, and add a few full blinks.

Can dehydration make blepharitis worse?

Yes. Low hydration increases tear film stress and can worsen symptoms.
