Protecting vision

Of the more than 600 plant pigments called carotenoids found in nature, only two carotenoids – zeaxanthin and lutein – selectively accumulate in the retina, macula and lens of the eye.

QUITE a number of conditions can lead to deteriorating vision, including near-sightedness, far-sightedness, presbyopia, astigmatism, glaucoma, aged-related macular degeneration and cataracts. As we age, we become increasingly susceptible to many of these problems.
