The sensitive tissues of your eyes may be particularly vulnerable to free radicals and this is why antioxidants play such important roles in maintaining eye health. Caruso’s Bilberry 15,000 also contains the carotenoid antioxidants Lutein and Zeaxanthin. Lutein and Zeaxanthin are both found in the macula and retina of your eye and are important for maintaining healthy eye function, as well as the health of the macula and retina. Bilberry helps to maintain healthy vision and assists with eye adaptation to variations in light intensity (such as night vision) and helps to relieve light sensitivity.
