Given that meso-zeaxanthin is not normally found in a standard diet, a stronger antioxidant than both lutein and zeaxanthin, and allows for a wider range of blue-light filtration, its presence in a supplement will undoubtedly be of benefit for maintaining visual performance.

When we compared the amount of macular pigment, which is comprised of lutein and zeaxanthin, present in the eyes of people with age-related macular degeneration to people without the disease, those with the lowest levels of carotenoid accumulation in the outer retina were significantly more likely to suffer from age-related macular degeneration than those with higher pigment levels, said Dr. Landrum. The difference in risk between those having the highest and lowest levels was 75 percent.

In my opinion, the best formulation for maintaining visual health, and for safeguarding vision into old age, would contain lutein, zeaxanthin and meso-zeaxanthin. Such a combination is optimal for shielding the central retina from damaging wavelengths of light, and from injury by free radicals.
