You can take fish oil, but if your overall diet is flooded with the other essential fatty acid — omega-6 — you may be working against yourself. The balance between omega-6 and omega-3 is one of the most important and least understood aspects of managing inflammation, including in your eyes.
Omega-3 vs omega-6: the tug of war
Both omega-3 and omega-6 are essential fats your body needs. The catch is that they compete for the same enzymes in your body, which convert them into signalling molecules called eicosanoids. Eicosanoids made from omega-3 are anti-inflammatory, while those made from omega-6 tend to be more pro-inflammatory. So the ratio between the two helps set your body's overall inflammatory tone.
The modern imbalance
A typical Western diet is heavily skewed toward omega-6, which is abundant in vegetable oils (corn, safflower, sunflower), processed foods and fried foods. The result: the average omega-6 to omega-3 ratio is around 15:1, when the ideal is closer to 4:1. In other words, most people are eating in a way that tilts their body toward inflammation.
Why this matters for dry eye
Dry eye and MGD are fundamentally inflammatory conditions of the lid margin and ocular surface. A diet that keeps your body in a pro-inflammatory state can make that inflammation harder to settle. Improving your omega-6 to omega-3 balance — by increasing omega-3 and moderating omega-6 — supports a calmer inflammatory environment where your eyes can recover.
How to improve your ratio
Increase omega-3: eat more oily fish (salmon, sardines, mackerel) and/or take a quality fish oil supplement.
Moderate omega-6: reduce processed and fried foods and heavy use of omega-6-rich vegetable oils.
Be consistent: like all dietary change, the benefit comes from a sustained shift, not a one-off.
Tip the balance: a daily high-potency fish oil like Meibocare LipidBoost+ is an easy way to boost your omega-3 intake and support a healthier inflammatory balance. Part of our dry eye packages.
Frequently asked questions
What is a healthy omega-6 to omega-3 ratio?
An ideal ratio is around 4:1 omega-6 to omega-3, but a typical Western diet is closer to 15:1 — skewed toward inflammation.
Does the omega ratio affect dry eye?
Because dry eye and MGD are inflammatory, a diet high in omega-6 and low in omega-3 can worsen the inflammatory environment. Improving the balance supports calmer eyes.
