The benefits of Pycnogenol® French maritime pine bark extract for vision
How does ageing impact our vision?
The natural ageing process affects the sharpness of vision, everyone experiences decreased accommodation of the lens to see clearly at near at higher age.
Apart from gradual stiffening, the lens will develop opacities. The light sensing cones and rods may also lose function with increasing age. The progression may occur more rapidly in some individuals than others. In addition to hereditary factors, lifestyle and dietary factors define the speed with which oxidative stress and metabolic factors cause cumulative damage to ocular tissues.
The retina is the tissue with the highest metabolic turn-over in the body, with the consequence of generating the highest oxidative stress. Furthermore, ocular tissues are exposed to energetic UV rays which generate reactive oxygen species. Metabolic conditions such as diabetes involve a pathologic oxidative stress known to deprive antioxidant vitamins.
How Pycnogenol® French maritime pine bark extract helps protect the eyes ?
The eye is characterised by a unique aqueous-lipid barrier which requires water-soluble antioxidants for the aqueous phase and lipid soluble antioxidants, predominantly carotenoids, for protection of the polyunsaturated fatty acid-rich retina. Five clinical studies with more than 1200 participants have demonstrated that Pycnogenol® improves the vascular system of the eyes to preserve healthy eyesight.
Under laboratory conditions Lutein and Pycnogenol® were investigated for their antioxidant protective effect of the retina. Further to their potent individual antioxidant contributions the combination of Lutein and Pycnogenol® showed additional synergistic protection of retinal lipids from oxidation by 60%.
