> **Summary:** Omega 3 fatty acids are polyunsaturated fats the body cannot make, so they must come from food such as oily fish, walnuts and flaxseed. They are needed for retinal development and function and support eye health as part of a balanced diet, but they do not treat eye conditions on their own, and supplements should be discussed with a doctor.

## What Is Omega 3?
Polyunsaturated fatty acids that support the eyes, heart and blood vessels, metabolism, energy, muscle development and the immune system. Omega 3 contains three different fatty acids from two sources:
- **Plant based:** alpha-linolenic acid (ALA)
- **Animal based:** eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)

## Foods Containing Omega 3
- **ALA:** flaxseed, purslane, walnuts, chia seed oil
- **EPA and DHA:** oily fish such as trout, salmon, sardines and mackerel; oysters, mussels and crab

## Benefits for the Eyes
- Omega 3 is necessary for the development and function of the retina; DHA helps preserve visual acuity.
- Some studies report macular degeneration is less common in people with omega 3 rich diets, but supplements have not been shown to lower this risk.
- There is no firm evidence that omega 3 prevents glaucoma, and it does not treat eye conditions on its own.

## Babies and Children
Intense brain development and rapid visual development occur in the two years after birth. Enough omega 3 through breast milk and complementary foods supports eye cell formation, clear vision, muscle and brain development. A paediatrician decides whether a supplement is needed and at what dose.

## Adults
With age and long screen use, eye health comes under pressure; omega 3 as part of a balanced diet supports eye health and other body systems.

## How to Take Omega 3
- First through diet, for example oily fish at least twice a week; grilling helps preserve omega 3.
- Eat plant based omega 3 oils regularly.
- Capsule supplements exist; there is no single dose that suits everyone, as needs vary with age, diet and health. Decide product and dose with a doctor.
