For dry eyes, a common recommendation is 1-2 tablespoons (15-30 ml) of liquid flaxseed oil or 3-6 capsules daily, aiming for about 1.5-3 grams of ALA omega-3, but doses vary, with some studies using higher amounts (around 2-3g ALA) or focusing on combined EPA/DHA. It's best to start low and consult an eye doctor (optometrist or ophthalmologist) for personalized advice, as there's no single official guideline.
Flaxseed oil and fish oil may help to treat and improve the symptoms of dry eyes. This is because they contain important dietary fatty acids that have multiple health benefits. These health benefits are believed to derive from omega-3 fatty acids needed by the body for vital functions and eyesight.
Vitamin B12
According to a 2017 study, a B12 deficiency is associated with severe dry eye and eye pain. A recent 2015 study found that the combination of oral vitamin B12 supplements and artificial tears improved symptoms of dry eye syndrome.
Dry eye treated orally with flaxseed oil has a high success rate, according to a 3-year follow-up study of 200 patients. "We found that 85% had total relief of their symptoms at the 2-month check," said investigator Carol R. Boerner, MD, an ophthalmologist in private solo practice.
Because fish oil contains natural EPA and DHA omega-3s (that don't have to be converted from ALA), many nutrition experts recommend fish oil over flaxseed oil. Grilled salmon is an excellent source of omega-3 fatty acids to fight dry eyes.
NYU Langone ophthalmologists often suggest the use of artificial tears for mild dry eye disease. This is an over-the-counter medication available as an eye drop that helps to replace or supplement the tear film, the natural layer of water, oil, and mucus that keeps the eyes moist.
Vitamin A deficiency, which usually occurs in developing countries, can cause an increase in dry eye. By adding foods rich in Vitamin A, like carrots, pumpkins, apricots, spinach, tomatoes, dairy products and liver, you can prevent the development of this condition. Vitamin B2 protects your eyes from cell damage.

What are the most important vitamins for eye health?
Flaxseed is commonly used to improve digestive health or relieve constipation. Flaxseed may also help lower total blood cholesterol and low-density lipoprotein (LDL, or "bad") cholesterol levels, which may help reduce the risk of heart disease.
Omega-3 fatty acids, most commonly found in fish and flax seeds, have been proven to decrease symptoms of dry eyes. Omega-3 reduces inflammation in the eyes and enables increased tear quantity as well as quality!
Our results revealed that flaxseed oil was more effective in reducing insulin and hs‐CRP levels than fish oil, although both flaxseed oil and fish oil had similar effects on other cardiovascular risk biomarkers. However, flaxseed oil tended to improve the overall survival rate when compared with fish oil.
Omega-6 and omega-3 fatty acids are flaxseed's protective components. Taken at bedtime, consuming flax seeds can increase your levels of fatty acids, which may help in fighting heart diseases by regulating blood cholesterol and lowering blood pressure.
Mango and papaya are full of nutrients that help support healthy eyes. Two key nutrients are the antioxidants lutein and zeaxanthin. These act as a natural sunblock, absorbing excess light coming into the retina. They also protect the eye from harmful blue light.
Reasons for tear film dysfunction are many, including hormone changes, autoimmune disease, inflamed eyelid glands or allergic eye disease. For some people, the cause of dry eyes is decreased tear production or increased tear evaporation.
Dry skin often responds well to lifestyle measures, such as using moisturizers and avoiding long, hot showers and baths. If you have very dry skin, your doctor may recommend a moisturizing product formulated for your needs.

Vitamin B6 is needed for a healthy tear film. Foods such as kale, potatoes, goose, mackerel, salmon and sardines contain high doses of vitamin B6. Vitamin B12 is also important for lubricating the eyes. It's typically found in mackerel, beef liver, calf's liver and pork liver.
Use artificial tears: Artificial tears are a mainstay to dealing with dry eye disease. I recommend using preservative-free artificial tears. This is because the preservatives that are used to keep bacteria from growing can damage the surface of the eye over time, causing even more irritation and redness.
Vitamin D. Early research has shown that vitamin D may be associated with dry eyes.
