The health of our eyes is one of the most important factors influencing our quality of life. Increased use of screens in everyday life, environmental pollution, poor eating habits, and advancing age can all affect the well-being of our eyes. In this context, one nutritional component comes into focus: omega-3 fatty acids.
But how exactly are omega-3 fatty acids related to eye health?
The special role of DHA in the retina
Docosahexaenoic acid (DHA), a long-chain omega-3 fatty acid, is a natural component of the retina—the light-sensitive tissue layer in the eye. DHA contributes to the structural stability and normal function of retinal cells, which in turn is important for maintaining normal vision.
Products like Ballstad Omega-3 contain high-quality DHA sources that are scientifically analyzed and processed according to strict quality standards.
Research findings on Omega-3 and vision
Age-related changes in central vision
Studies have described a link between a diet rich in DHA and EPA and better macular health in older adults. Adequate omega-3 intake could therefore be a building block for long-term support of central visual function.
Dry eyes
Tear film quality also plays a role in subjective eye comfort. Some studies have observed that a diet rich in omega-3 fatty acids can have positive effects on tear film stability. This may be relevant as a complementary approach for people with dry eyes.
Myopia in childhood and adolescence
Research is currently underway to determine whether omega-3 fatty acids might contribute to the regulation of ocular development. Initial observations suggest that certain fatty acids may influence blood flow in the eye and the longitudinal growth of the eyeball. However, further studies are needed for a definitive assessment.
Diabetes-related retinal changes
Omega-3 fatty acids are being scientifically studied for their general vascular protection. Preclinical studies have analyzed whether they can support inflammatory processes and stabilize blood vessels in the eye—particularly in connection with diabetes-associated changes. Medical advice is essential in this regard.
Conclusion
Omega-3 fatty acids, especially DHA, make a nutritionally valuable contribution to supporting normal vision. The combination of targeted intake of high-quality fatty acids—for example, through certified products like Ballstad Omega-3—and a balanced lifestyle can help ensure optimal eye care in everyday life.
Important: Dietary supplements are not a substitute for a varied, balanced diet and a healthy lifestyle. If you have any existing medical conditions or complaints, you should always seek medical advice.
