Researchers haven't been able to find early causes or the symptoms related to the disease. Doctors use medication to reducing the pressure on the eyes, but there is currently no cure for it. In addition to medication, having a proper diet can also help keep it under control.

For people already suffering from glaucoma, adopting a healthy lifestyle is vital. This healthy lifestyle includes regular exercise and a nutritious diet. A nutritious diet is also important for reducing the risk of getting glaucoma.

As you can imagine, our focus should always be to strengthen the vision. Food rich with carotenoids, antioxidants, Vitamin A and D, zinc and omega fatty acids can contribute to the cause. 

Of course, no food will serve as a magic pill to cure glaucoma or make you immune to it. But these foods can reduce the risk of getting it or make it easier to live with it!

Wild-caught salmon is one of the best sources of EPA and DHA. Along with water fish such as tuna, sardines and herring that contain acids that improve ocular blood flow which thus decreases the risk of glaucoma.
