Those itchy, scratchy dry eyes of yours are caused by a lack of tears.
More and more Eye Doctors are recommending nutritional solutions for dry eyes instead of temporarily dealing with the symptoms (Expensive eye drops, anyone?)
Omega-3s and other fatty acids increase the amount of tears you produce and reduce your dry eye symptoms.
Dry eyes are an inflammatory issue – like so many other Western diseases. One of the main causes of dry eyes is a Meibomian Gland Dysfunction. Your “my-bohemian” gland produces oil that stops your tears from evaporating.
You are going to have dry eyes if your tear film is evaporating too fast. If you don’t have enough "my-bohemian" oil your already limited tears will evaporate quickly and you'll be rubbing your dry eyes red again.
So why don’t you have enough “my-Bohemian” oil?
If your glands are clogged your tear oil isn’t reaching your eyes.
This is what clogged “my-Bohemian” glads look like: ( Forewarning, it’s not pretty)
Omega-3s can help reduce the waxy build up that clogs Meibomian glands.
(Just like omega-3s help prevent clogged arteries and cardio vascular disease.)
Omega-3s also help prevent inflammation that exasperates the clogging of the gland. If glands are swollen and inflamed wax is more likely to build up. If your glands are relaxed and wide they won’t clog.
Omega-6s typically cause inflammation. Patients with dry eyes had a higher ratio of omega-6:omega-3 in their tear film. The worse the dry eyes, the more drastic the difference in omega-6s to omega-3s.
Omega-6s are found in processed foods and other ingredients typical in a modern diet. Fish is the best source of a particular omega-3 called DHA that is vital to eye health.
If you have more omega-3s in your tears you will also have more tear volume. With more tears you may not have dry eye symptoms at all!
Plus we've learned omega-3s help "my-bohemian" oil reach your eyes so that your tears don't evaporate. The benefit is 2 fold.
Omega-3s = More Tears & Anti-Evaporating Tear Oil
Therefore, Omega-3s = Less Dry Eyes
So, how do you know if you've got enough omega-3s?
You can learn if low omega-3 levels and a high omega-6:omega3 ratio may be contributing to your dry eyes by taking the Omega Blood Score.
Pay particular attention to your DHA level. The retina has the highest concentration of DHA in the whole body. If you are deficient in DHA your eyes may be suffering.
Also, look at you omega-6:omega-3 and GLA values.
Remember, a high omega-6:omega-3 value means you aren't producing the optimal tear volume and your "my-bohemian" oil may be clogging.
Gamma Linolenic Acid (GLA) is a very unique omega-6 that has some anti-inflammatory qualities.
