How Omega-3 Fights Myopia in Young Children

A recent global study reveals that omega-3 fatty acids and myopia prevention are closely connected. Researchers found that children who consume more omega-3 fatty acids through their diet are less likely to develop myopia (shortsightedness). The findings, published in the British Journal of Ophthalmology, offer the first strong evidence in humans suggesting that omega-3 fatty acids can help protect young eyes from developing this common vision problem.

Omega-3 Fatty Acids: A Natural Protector

Omega-3 fatty acids, mainly found in fish oil and certain plant sources, are already known for supporting heart and brain health. Now, research suggests that these fats could also play a key role in myopia prevention. The study shows that children who consume higher amounts of omega-3 fatty acids tend to have shorter axial lengths and lower levels of myopic refraction.

Prof. Jason C. Yam from the Chinese University of Hong Kong, the study’s lead author, explained that omega-3 fatty acids may improve blood flow in the choroid – a layer of blood vessels in the eye responsible for supplying nutrients and oxygen. This helps prevent oxygen shortage in the white of the eye (scleral hypoxia), which is believed to be a major factor in myopia development.

Saturated Fats May Increase Myopia Risk

Interestingly, the study also found the opposite effect with saturated fats, which are abundant in butter, palm oil, and red meat. Children who regularly consumed higher amounts of saturated fats were more likely to develop myopia. This highlights not just the benefit of omega-3 fatty acids but also the risk of a poor dietary pattern.

Study Details: Real-Life Data from Over 1,000 Children

The research team analysed data from 1,005 children aged 6 to 8 years in China. They examined the children’s eyesight, diet, and physical activity habits. Around 27.5% (276 children) already showed signs of myopia. By comparing diet patterns, they found a clear link: higher omega-3 intake correlated with a lower chance of having myopia, while saturated fat intake was associated with a higher risk.
Therefore, it shows associations but cannot prove direct cause and effect. Moreover, diet information was collected using food frequency questionnaires, which depend on memory and reflect only a brief snapshot of the children’s eating habits.

Conclusion

This important study strengthens the case for the role of omega-3 fatty acids and myopia prevention in children. While it doesn’t prove causation, it supports the idea that a diet rich in omega-3s alongside lower saturated fat intake can help keep children’s vision healthy. Experts suggest that parents consider including more fish, flaxseeds, and walnuts in their child’s diet as a preventive strategy.
As myopia continues to rise among the younger population, such dietary insights may prove invaluable in slowing its progression. Further research is needed, but the current findings offer a promising step toward simple, everyday prevention.
