Failing Eyesight? Eat more fish

If your eyesight is failing, eat more oily fish, and take omega-3 supplements every day.  This combined strategy can help re-grow blood vessels in the eyes and combat retinopathy, the eye disease that can lead to blindness.

It’s also vital to reduce – or eliminate – the amount of omega-6 fatty acids, which are derived from corn oil and which form the backbone of the standard American diet.  The omega-6 acids aid the growth of abnormal blood vessels in the retina.

By comparison, the omega-3 fatty acids EPA and DHA, mainly derived from fatty fish and vegetables, encourage the growth of healthy blood vessels in the eyes.  They also protect against the growth of abnormal blood vessels, a characteristic of retinopathy.

Researchers from Harvard Medical School found that even a slight increase in omega-3 had a profound effect on eye problems, halving the severity of retinopathy.
