Essential fatty acids may also help the fluid inside the eye drain properly and lower the risk of glaucoma, which can happen when inner eye pressure is too high. This US-based trial did not find a difference on several measures compared with placebo over one year of follow up. Macular degeneration is a condition that causes gradual vision loss in the center of your field of view.

However, there are a number of eye conditions that might require further medical attention, so that last one suggestion is especially important if you notice any sudden changes in your vision. https://www.hsph.harvard.edu/nutritionsource/what-should-you-eat/fats-and-cholesterol/types-of-fat/omega-3-fats/ Product purity: Look for products that have either the GOED standard for purity or a third-party seal that indicates they’ve been tested by an independent lab and the contents are safe and contain what the label says.For most people, sight is one of the more precious senses and it provides many of our most important clues about the world around us. During one study, rats were fed a combination of safflower, flaxseed and tuna oils — all high in omega-3s. The results showed that the diet helped regulate the outflow of the eye’s inner fluid, a critical part of preventing high eye pressure and, eventually, glaucoma. Bhargava R, et al. (2016). A randomized controlled trial of omega 3 fatty acids in rosacea patients with dry eye symptoms. DOI:

In a study of more than 32,000 women between the ages of 45 and 84, those with the highest ratio of omega-6s to omega-3s in their diet (15-to-1 ratio) had a significantly higher risk of developing dry eye syndrome, compared with the women with the lowest ratio (4-to-1 ratio or less). Dry eye disease is a long-term, inflammatory, age-related condition leading to discomfort, eye-tiredness, and visual disturbances. These symptoms can impair quality of life and everyday activities, such as reading and driving. Both omega-3 and omega-6 fatty acids play a role in your health, but it’s important to keep the two balanced.

Adequate amounts of DHA and other omega-3 fatty acids in the diet of pregnant women also appear to be important in normal infant vision development. What we do know, however, is that eating fish offers all kinds of naturally occurring vitamins and minerals too, such as vitamin D, calcium, iron, zinc, magnesium, and more.

As an academic and an ophthalmologist [eye doctor], I read everything I could about this, but there hadn't been very much research. And the information available was not very good. That's when I decided to conduct a clinical trial and find out if it's useful for dry eye disease. What were the results? Dry Eye Assessment and Management Study Research Group, Asbell PA, Maguire MG, Pistilli M, et al. n-3 fatty acid supplementation for the treatment of dry eye disease. N Engl J Med. 2018;378(18):1681-90. Bibliography Vehof J, Kozareva D, Hysi PG, Hammond CJ. Prevalence and risk factors of dry eye disease in a British female cohort. British J Ophthalmol. 2014;98(12):1712-17. There was no significant difference in the primary outcome at one year (mean change in OSDI score) between those treated with omega-3 fatty acid supplements and those prescribed an inactive placebo (-13.9 points and -12.5 points, 95% confidence interval -5.0 to 1.1, where higher score denotes more severe disease). This suggests a small “placebo effect” with both oils. The American Academy of Ophthalmology guidelines (published 2013) advises that omega-3 fatty acid products may be beneficial in the treatment of dry eye. Although they sayevidence is insufficient to support the effectiveness of any particular formulation.https://www.aoa.org/patients-and-public/eye-and-vision-problems/glossary-of-eye-and-vision-conditions/dry-eye?sso=y Cells, muscles, nerves and organs need fatty acids to work correctly. The hormone-like compounds that help regulate blood pressure, heart rate and blood clotting also rely on fatty acids. This imbalance of omega-3s (good) and omega-6s (not as good) appears to contribute to a higher risk of serious health problems, such as heart disease, cancer, asthma, arthritis and depression. Zhu W, et al. (2014). Efficacy of polyunsaturated fatty acids for dry eye syndrome: A meta-analysis of randomized controlled trials. DOI: While both omega-3 and omega-6 fatty acids are important to health, the balance of these two types of EFAs in our diet is extremely important. Most experts believe the ratio of omega-6 to omega-3 fatty acids in a healthy diet should be 4-to-1 or lower.

I also monitor their progress over time with imaging and TearLab Osmolarity testing, as we can objectively and quantifiably show patients that the treatment works. In my experience, this aids compliance. If patients see that their images and numbers are improving, even though they might not be feeling better in the early stages of treatment, they’re likely to continue with the therapy. An eye doctor can help you learn if you have any of these problems. The data suggest that one of the greatest reasons people go to an eye doctor is the presence of dry eye disease. They want to lessen the pain they're experiencing.NIH study provides clarity on supplements for protection against blinding eye disease. National Eye Institute. May 2013. There was also no significant difference between the treatment groups for the trial’s secondary outcomes (conjunctival staining score, corneal staining score, tear break-up time, and Schirmer’s test).
