While hygiene is the foundation of blepharitis management, the right supplemental products can significantly speed up relief and improve comfort. However, using the wrong products can actually make inflammation worse.
Eye drops for blepharitis
The best eye drops for blepharitis focus on comfort and surface protection. They do not cure the condition, but they reduce irritation while you treat the lid margin.
1. Artificial Tears / Lubricants
Blepharitis almost always causes an unstable tear film (Evaporative Dry Eye). Lubricating drops help stabilize the tears and soothe the ocular surface.
The Golden Rule
Always choose Preservative-Free (PF) drops if possible. Preservatives like BAK can be toxic to corneal cells and increase inflammation—exactly what you want to avoid.
Many standard eye drops contain preservatives like Benzalkonium Chloride (BAK). While effective at keeping the bottle sterile, BAK is toxic to the corneal cells with frequent use.
- Look for: Single-dose vials or multi-dose bottles with special "ABA" or "COMOD" filters that prevent backflow bacteria.
- Ingredients: Hyaluronic Acid (Sodium Hyaluronate) is a gold-standard ingredient for its ability to retain water and heal the surface.
2. Ointments for Night Time
If you wake up with very dry, gritty eyes, a lubricating ointment or gel used just before bed can be a game-changer. These are thicker than drops and will blur your vision, so they are only for sleep. They provide a physical barrier preventing the eyes from drying out if your eyelids don't close fully (lagophthalmos).
3. Antiseptic Sprays (Hypochlorous Acid)
Hypochlorous acid (HOCl) is a naturally occurring molecule produced by our white blood cells to fight bacteria.
Sprays containing stable pure hypochlorous acid are highly effective at reducing the bacterial load (biofilm) on the eyelids without stinging or causing antibiotic resistance. They are excellent for patients who find scrubbing difficult.
4. Omega-3 Supplements
Diet plays a role in the quality of the oil your meibomian glands produce.
"Oral Omega-3s work from the inside out to make the oil in your glands more fluid and less prone to clogging."
Oral Omega-3 fatty acid supplements (specifically those high in EPA and DHA) have anti-inflammatory properties.
- Source matters: Triglyceride-form fish oils are generally better absorbed than ethyl ester forms. Flaxseed oil is a plant alternative but may be less efficient at conversion in the body.
- Dosage: Consult your doctor, but therapeutic doses often range around 2000mg daily.
What to Avoid
Whitening Drops (Vasoconstrictors)
Avoid "get the red out" drops. These work by shrinking blood vessels. They treat the symptom, not the cause, and can lead to a "rebound effect" where eyes become even redder once the drop wears off. They can also mask signs of infection.
