With so much time spent in front of screens, problems like dry eyes and vision fatigue are becoming more common. Age-related eye conditions are also on the rise. That’s why many people turn to omega-3 for eyes and vision. It’s a natural, research-backed way to improve comfort and protect long-term visual health. In particular, omega-3 for dry eyes helps improve moisture retention. It also supports retinal function for sharper sight. These essential fats—especially DHA and EPA—relieve persistent dry eye symptoms. They also help protect against macular degeneration. Together, they keep your vision clear and healthy as you age.
Bottom line: Consistent omega-3 intake – through diet or supplements – can help keep eyes hydrated, protect against vision loss, and maintain sharp sight as you age.
Omega-3 fatty acids are essential polyunsaturated fats found in a variety of foods, including fatty fish and plant-based sources. Among their many health benefits, they play a critical role in protecting and maintaining eye health. To sum up, the three most relevant omega-3s include:
ALA is commonly found in flaxseeds, chia seeds, and walnuts, while DHA and EPA are abundant in cold-water fatty fish like salmon, sardines, and mackerel. If you are a person who struggles to get enough of these fatty acids through diet alone, high-quality supplements are widely available.
Omega-3s work best as part of a well-rounded nutritional approach that includes eye-friendly vitamins like A, C, and E, along with antioxidants such as lutein and zeaxanthin to help protect against long-term vision damage.

Dry eyes can cause stinging, light sensitivity, blurred vision, and that persistent gritty feeling. Omega-3 fatty acids – especially DHA and EPA – can help by improving the function of your tear glands and reducing surface inflammation. They also contribute to overall comfort, which may ease feelings of eye fatigue from extended screen use.
How Omega-3 for Dry Eyes Help:
| Omega-3 Benefit | Type (EPA or DHA) | How It Helps Dry Eye Symptoms |
|---|---|---|
| Improves tear film stability | DHA | Supports the oily layer of the tear film, reducing tear evaporation and dryness |
| Reduces surface inflammation | EPA | Minimizes redness, burning, and irritation by calming inflammation |
| Enhances overall eye comfort | EPA & DHA | Promotes a more hydrated and less irritated ocular surface |
| May reduce need for artificial tears | EPA | Improved natural tear production can lower dependency on eye drops |

Age-related macular degeneration (AMD) affects the central part of your vision and is one of the leading causes of vision loss in adults over 50. These fatty acids – particularly DHA – have been shown to help slow the progression of AMD and protect retinal cells from damage.
Diets high in omega-3s are linked to a significantly lower risk of AMD. In fact, these essential fats help preserve the structure and function of the macula, which is responsible for sharp, detailed vision.
| Diet Group | Omega-3 Intake | Observed AMD Risk | Key Notes |
|---|---|---|---|
| High Intake Group | Fish or supplements ≥ 2 times/week | Up to 50% lower risk | Regular DHA and EPA intake linked to slower AMD progression |
| Low Intake Group | Fish or supplements < 1 time/week | Higher risk of AMD | Insufficient fatty acid levels may compromise retinal protection |

Beyond helping with dry eyes and AMD, omega-3s offer broad support for overall eye function. They help nourish the retina, regulate eye pressure, and may even protect against other age-related vision issues.
Key benefits include:
To further support your eye health, EyeFortin offers a premium, all-natural eye care supplement designed to help maintain retinal and visual health.
Getting omega-3s from food is the most natural and effective way to support your eyes. While supplements are helpful, whole food sources provide additional nutrients that work together to protect your vision.

Not everyone gets enough of these fatty acids through diet alone. In fact, if you don’t eat fish regularly or follow a plant-based lifestyle, a supplement can help fill the gap. Fish oil supplements offer a concentrated source of DHA and EPA – making them a convenient way to support eye health year-round.
Top benefits of supplementation:
For a high-quality option, consider Clear Crystal Vision. This supplement is formulated to provide clarity, comfort, and lasting support for your visual system.
For optimal eye support, most studies recommend around 1,000 mg per day of combined DHA and EPA. This amount can come from fatty fish, supplements, or a combination of both.
Tip: Keep your omega-3 to omega-6 ratio balanced. Excess omega-6 – found in many processed foods – can interfere with the anti-inflammatory benefits of omega-3s.
Does it help to take omega-3 for dry eyes?
Yes. Omega-3 fatty acids – especially EPA and DHA – help reduce inflammation and improve the oily layer of the tear film. This slows tear evaporation, enhances moisture retention, and offers lasting relief from dry eye discomfort.
Can omega-3 prevent macular degeneration?
While omega-3s can’t completely prevent AMD, they may slow its progression and protect retinal cells. DHA is a major component of the retina, and consistent intake helps maintain its structure and function.
What are the best plant-based sources of omega-3?
Top plant-based sources of ALA include flaxseeds, chia seeds, walnuts, and hemp seeds. While ALA must be converted into EPA and DHA, including these in your diet still supports general eye and brain health.
Adding omega-3 fatty acids to your daily routine is one of the simplest and most effective ways to protect your vision. Whether you’re eating fatty fish, using supplements, or doing both, DHA and EPA offer clear benefits – from relieving dry eye symptoms to reducing the risk of macular degeneration.
Stay consistent with your intake, pair it with a healthy lifestyle, and give your eyes the support they need to stay sharp and comfortable for years to come.
