Proven? Really? Can you point to the independent studies or refereed journal articles?I just take a no name multi vitamin from Walmart that's advertised for vision. It contains Lutein, the same stuff the brand name guys are selling but a fraction of the price. Won't prevent presbyopia now that I'm over 40 but proven to help the retina.

If you understand clincal research endpoints, you would not feel this way.Why is it always like being in a court room on this site?
But that has never been proven.Lutein and Zeaxanthin are powerful antioxidants that our bodies cannot produce on their own. These vital nutrients help filter harmful blue light, the kind of light which can damage the macula, the region of the retina responsible for central vision.
Observational studies have noted that higher dietary intake of lutein and zeaxanthin is related to reduced risk of cataracts and age-related macular degeneration, two eye conditions for which there is minimal options when it comes to effective prevention.
Research published in Nutrition & Metabolism found that a nutritional supplement containing meso-zeaxanthin, lutein and zeaxanthin effectively increased the optical density of the macular pigment in eyes of the majority of human subjects. The macular pigment is believed to offer protection against the development of macular degeneration
Short term, maybe. Long term- nada.Beyond reducing the risk of developing eye disease, separate studies have shown that lutein and zeaxanthin improve visual performance in AMD patients, cataract patients and individuals with good health.
I dunno. Should I apply that argument to Allegra, Cialis, Lipitor, Zocor, Cymbalta, Ambien and the dozens of others that are hawked from billions of dollars worth of TV and magazine ads?So. Think for a minute. If they really worked, would they be relegated to advertisements?
This is the second time you have beaten me to a post that I was about to make.I dunno. Should I apply that argument to Allegra, Cialis, Lipitor, Zocor, Cymbalta, Ambien and the dozens of others that are hawked from billions of dollars worth of TV and magazine ads?
But I do get your point. I assume these things are made with a heavy dose of snake oil, just playing devil's advocate.
my aunt has been taking Ocutvie from Bausch & Lomb. says its helped her vision and she doesn't need her glasses when doing up close work anymore.
i have no idea what her prescription or eyesight is like though and it could be just her imagination.
As far as I know, the only proven benefit of vitamins on the eye is with the AREDS preparation with regard to slowing the advancement of moderate macular degeneration. (One variant offered by Ocuvite, among other manufacturers) is the AREDS formula). Even then, the vitamins have never been shown to make anything BETTER. Also, antioxidants are thought to retard the onset of certain cataracts.

Research - Lutein and Zeaxanthin and AMD
One of the first large studies on carotenoids is the Eye Disease Case Control Study, in which diet was compared to the risk for developing AMD. Results found a significantly lower risk for developing the eye disease in people with high amounts of lutein+zeaxanthin in their blood. Also, those people eating a diet with the most lutein+zeaxanthin (as much as 5.8 milligrams (mg) per day) had a significantly lower risk for AMD than those whose diet contained the least amount (as low as 1.2 mg per day). Dietary studies confirmed the association between frequent consumption of spinach or collard greens, particularly good sources of lutein and zeaxanthin, and lower AMD risk.
Similar results were found in a recent analysis of a national dietary study called the Third National Health and Nutrition Examination Survey or NHANES III. This analysis also showed that consuming 6 mg per day of lutein+zeaxanthin was associated with reduced risk for developing AMD.
Seems like it's proven to me. Maybe this isn't valid research, I don't know. How many prescription meds do we take that are proven to work but only for some people with certain conditions? Not everything is 100 % effective, but like I said if I'm going to take a multivitamin everyday, why not one with Lutein?
