Dry eye syndrome can often feel like sand in your eyes. Sometimes, it can feel like a blurry, filmy feeling that you can’t blink away.
However, dry eyes are more than just an annoyance. They can cause significant discomfort and potentially interfere with your daily life.
Can Omega-3 Fatty Acids Help with Dry Eye Syndrome?
Omega-3s, especially EPA and DHA, are healthy fats in foods like fish and flaxseeds. These fats protect your heart and play a significant role in fighting inflammation.
Although inflammation is necessary for the healing process, it can sometimes become excessive. Chronic inflammation is a major factor in dry eye syndrome, so having some omega-3s can help balance things out.
Multiple studies show that omega-3 supplements can help relieve dry eye symptoms. People report less of that dry, gritty feeling, less sensitivity to light, and even better vision.
How Do Omega-3 Fatty Acids Work?
Your tears comprise several layers designed to nourish and protect your eyes. One of these layers is an oily layer where omega-3s can help.
Increasing your omega-3 intake can help the glands in your eyelids produce more oily layers. More oil means your tears don’t evaporate as quickly, keeping your eyes comfortable for longer.
The Benefits of Omega-3 Fatty Acids on Overall Eye Health
The omega-3 index measures the amount of omega-3 in red blood cells. If you have a good amount of omega-3 in your system, your risk of getting dry eye is significantly lower. On the other hand, if your omega-3 index is low, you might need to increase your intake.
However, having a healthy amount of omega-3 in your body can have various benefits, including:
- Delaying macular and age-related macular degeneration (AMD) progress
- Reduced risk of glaucoma
- Improved eye health for infants
- Maintaining retina health
Some Considerations for Omega-3 Fatty Acids
Although omega-3 can benefit eye health, it isn’t a magic cure for eye problems. For example, early studies on omega-3 for preventing AMD show mixed results.
On the other hand, omega-3 supplements can affect people differently. Certain people might benefit from omega-3 based on individual factors, and these factors haven’t been clearly defined by researchers.
However, omega-3 can contribute to your overall eye health to some degree. You’ll just need to temper your expectations.
Should You Take Omega-3?
Whether or not you should take omega-3 is a conversation for your doctor. Although it has many benefits, your doctor will know how it will affect you.
They’ll typically look at certain factors to determine whether omega-3 supplementation is right for you:
- Age
- Family history of AMD
- Current eye health
- Overall diet
- Pregnancy
Choose high-quality omega-3 supplements with EPA and DHA and discuss dosing with your doctor.
How to Choose the Right Supplements For You
There are many sources of omega-3, from food to supplements. As mentioned before, you can get omega-3 from fish, flaxseeds, dairy, and eggs. However, EPA and DHA can also be obtained from fish, krill, and algae oil.
Supplements are a different question altogether. Here are some tips to help you spot quality supplements:
- Read the label carefully: Don’t just go by the total amount of fish oil listed. Check for the actual amounts of EPA and DHA.
- Look for certification seals: Reputable brands often carry seals from organizations like IFOS, USP, or NSF, ensuring their products have been independently tested.
- Smell: A supplement with a strong fishy odor may be oxidized, which can be harmful.
- Choose reputable brands: Research and stick with companies with a positive reputation for quality and transparency.
- Talk to your doctor: They can offer personalized advice, especially if you take medication or have other health conditions.
- Pay attention to purity: Choose third-party certified supplements for purity to ensure they’re free from contaminants like mercury and PCBs.
- Dosage: Look at the amount of EPA and DHA per serving. To support eye health, aim for at least 1000mg combined EPA and DHA daily.
- Triglyceride: Triglyceride and re-esterified triglyceride forms tend to be better absorbed than ethyl esters.
Omega-3 fatty acids, particularly EPA and DHA, can be a valuable addition to your eye care routine. While they might not be a miracle cure, they can play a significant role in keeping your eyes comfortable and healthy. But as always, consult your doctor to determine the best approach for your specific needs.
