Fish oil, which contains omega-3 fatty acids, may help prevent glaucoma. It can lower intraocular pressure and improve blood flow in the eye. Research shows that omega-3 supplements may reduce eye pressure. Regular use may also help treat dry eye and support overall eye health.
Additionally, omega-3s may protect against dry eye syndrome, a common eye issue that can complicate glaucoma. Dry eyes often occur when the body does not produce enough tears or when tears evaporate too quickly. By supporting tear production and maintaining moisture, fish oil can alleviate symptoms related to both dry eyes and glaucoma.
While fish oil supplements show promise in promoting eye health, they should not be seen as a standalone treatment. It is essential to consult with a healthcare provider before starting any supplement regimen. Further research is needed to determine the exact effects of fish oil on glaucoma. Understanding these effects will allow for better management of eye health and potentially highlight preventive measures.
In the next section, we will explore additional lifestyle changes that can support eye health alongside fish oil supplementation.
