5. Consume Omega-3 Fats
Omega-3s may improve tear quality and decrease inflammation in dry eyes. These healthy fats are found in oily fish, such as salmon, mackerel, herring, lake trout, sardines, and albacore tuna. Other sources include flaxseeds, walnuts, and soybean and canola oils. Or ask your eye care professional about omega-3 supplements.
