How DHA can save your vision & your wallet

New glasses... again???

Seems like you only bought your current lenses last year... yet here you are at the eye doctor again, squinting at yet another big bill for yet another new set of lenses.

But there may be an easy way to protect your eyes and help ensure that those lenses last a little longer this time, and that's with the same omega-3 fatty acids you should be getting anyway.

In a new study, researchers found that mice fed the omega-3 fatty acid DHA -- one of the main fats in fish oil -- saw no increase in toxins in the retina, while those that didn't get fish oil saw the normal rise in toxins.

As a result, the mice that got the fish oil managed to avoid some of the vision loss that usually comes naturally with aging.

The researchers are now launching a second study, this time on humans, to see if DHA can help limit the damage of age-related macular degeneration. That's the leading cause of blindness in people over 50, and the research so far has been very encouraging.

A 2010 study, for example, found that omega-3 fatty acids can cut the risk of the "wet" form of AMD by 35 percent, and the dry form by 32 percent.

Omega-3s might help with other eye diseases as well. A Harvard study earlier this year found that just 200 mg of omega-3 fatty acids can delay blindness in patients with retinitis pigmentosa by up to 18 years.

There's no drug that can do that -- just fish oil, so make sure you're getting in on this all-natural miracle.
