Higher levels of vitamin D in the diet may support a lifetime of healthy vision, according to a new study out of Tufts Medical Center. The findings provide even further support for the idea that the health benefits of the nutrient are far reaching.

For the study, researchers administered dietary surveys to a group of participants and analyzed their medical records over a period of several decades. The results showed that those who consumed higher levels of vitamin D through food sources such as milk, fatty fish and eggs were less likely to experience problems later in life.

"Eat a healthy diet with lots of fruits and vegetables, and that can make a difference," said Johanna Seddon, who led the investigation.

She added that many people have preexisting genetic risk factors for vision problems. While these cannot be eliminated, it may be possible for these individuals to support healthy vision through diet and nutritional supplementation.

As a side note, the study also found that smokers were more likely to experience loss of vision, underscoring the importance of avoiding tobacco use.
