Omega-3 fatty acids are essential fatty acids that your body uses to produce new cells, muscles, nerves and organs. Several studies suggest that omega-3 fatty acids may help protect your eyes from age-related macular degeneration (AMD) and dry eye syndrome. Your body cannot produce omega-3 fatty acids, so you must get them from your food or supplements.
You should always consult your doctor before adding any vitamin or mineral supplements to your diet.
Sources of Omega-3 Fatty Acids
The foods richest in omega-3 fatty acids are cold-water fish such as sardines, herring, salmon and tuna. Eye doctors typically recommend a diet high in omega-3 fatty acids to reduce the risk of eye problems. Other foods containing omega-3 fatty acids are flaxseeds, walnuts and dark green leafy vegetables.
Eye doctors caution that, while you should increase your consumption of omega-3 fatty acids, you should be careful at the same time to limit omega-6 fatty acids, which interfere with your body's ability to absorb and use the "good" omega-3 fats. Foods high in omega-6 fatty acids include fried and highly processed foods such as those made with cooking oils and trans-fats.
