Blackmores Lutein-Vision Advancedâ„¢ is a macular defence
formula based on the latest scientific eye research. It contains
lutein and zeaxanthin (found in high concentrations in the
macular area) which have been shown to increase the density of
the protective macular pigment of the retina and contains
omega-3 fatty acids important for macular health. Selenium has
also been added for its antioxidant role in maintaining eye
health.suggest that supplements containing natural lutein and
zeaxanthin esters may increase the density of the macular
pigments . Higher macular pigment density is associated with
healthier eyes and the retention of visual sensitivity.
In
addition to absorbing potentially harmful blue light, lutein and
zeaxanthin also function as antioxidants and may help reduce
the risk of age-related macular damage by decreasing the
cumulative effects of oxidative damage to the retina and lens .Selenium
Lutein-Vision
Advanced™ contains selenium as selenomethionine, an
easily absorbed form of selenium . Selenium may play an
important antioxidant role in the eye as part of an antioxidant
enzyme called glutathione peroxidase (GSH). GSH is
concentrated in the lens where it has an important role in
preserving the clarity of the lens and preserving healthy eye
function .
Omega-3 fatty acids
/>Several studies have found that higher intakes of
omega-3 fatty acids and fish are associated with better macular
health . Very high levels of polyunsaturated fatty acids,
particularly DHA (docosahexaenoic acid), are present in the
retina, specifically in photoreceptor cells and the vascular part of
the retina.
The photoreceptors are constantly being
renewed and therefore a constant supply of DHA may be
required for proper retinal function. A marginal depletion may
make the retina more vulnerable to damage .
