Fish for the eyes

While fish has had a rough time of it lately due to mercury and other issues, two studies out now suggest that fish may prevent some kinds of blindness.

From Yahoo:

"Two new studies give one more reason to eat a diet rich in fish: prevention of age-related macular degeneration, the leading cause of blindness in old age"

and later:

"The omega-3 fatty acids found in fish such as salmon are already known to help the heart and brain stay healthy. The new studies, appearing Monday in the Archives of Ophthalmology, add to evidence that fish eaters also protect the eyes.The new studies aren't the strongest level of scientific evidence, but they confirm the findings of previous studies that also link fish consumption with prevention of macular degeneration"
