Increasing the intake of omega-3 and omega-6 fatty acids may help ease the symptoms of dry eyes; however, more research is necessary to prove this theory, according to Mayo Clinic. Foods that contain omega-3 and omega-6 fatty acids include salmon and sardines.
Chia seeds, flaxseeds, palm oil and walnuts also contain high amounts of omega-3s, notes Healthline. Omega-3 fatty acids may help people suffering from dry eyes by reducing inflammation and improving overall tear production. Individuals producing few to no tears are more likely to experience blurred vision, redness, scratchiness, sensitivity to light and other symptoms associated with dry eyes.
