These are fatty acids obtained from deep sea fish. There is some thought that Omega-3 supplements may help with macular degeneration, but they haven’t been as beneficial as once hoped (see the AREDS 2 Study). Also, these fatty acids improve oil flow in the skin and may help with dry eye and the meibomian gland dysfunction found in blepharitis. The two types of Omega-3 acids most studied are the DHA and EPA variety. The best source is cold water fish such as salmon, tuna, herring, and (yuck) sardines. If you aren’t a fish lover, omega-3s are available as supplements, both in oil and pill form. Vegetarians can get omega-3s from flaxseed, walnuts, and dark leafy vegetables.
