Omega-3 fatty acids are often recommended for dry eyes \u2013 but is there anything to it? Can diet really influence the ocular surface? In this article we summarise in plain terms what omega-3 can do, where the limits are, and what to keep in mind.<\/p>\n\n

Can diet affect dry eye?<\/h2>\n\n

It sounds surprising, but yes, a little. The oil that stops your tears evaporating is influenced by the fats you eat, so good nutrition can help support a more stable tear film. Keep this in proportion, though: diet won\u2019t cure dry eye or replace your treatment \u2013 it works as a complementary part of treatment.<\/p>\n\n

Why omega-3 gets almost all the attention<\/h2>\n\n

Of all the nutrients, omega-3 is the one most consistently linked to the comfort of the patient\u2019s ocular surface. This is because it has a natural anti-inflammatory effect, and inflammation is a central driver of dry eye. It also seems to improve the quality of the oil your glands produce \u2013 making it less thick and better able to spread \u2013 so the tear film evaporates more slowly. That\u2019s exactly what most people with dry eye need.<\/p>\n\n

Omega-3 versus omega-6<\/h2>\n\n

It isn\u2019t only how much omega-3 you get, but how it balances against omega-6. Modern diets tend to be heavy in omega-6 (abundant in processed foods and many vegetable oils) and comparatively light in omega-3. Because these fats compete in the body\u2019s inflammatory pathways, shifting the balance often has more impact than simply adding a supplement on top of your diet.<\/p>\n\n

The best food sources<\/h2>\n\n

Food is an excellent place to start, and several choices are rich in the right fats:<\/p>\n\n
