Macular pigment is yellow in colour and absorbs damaging blue light.Lutein and zeaxanthin are dietary carotenoids that filter damaging high-energy blue wavelength light from the visible-light spectrum by as much as 90%. Lutein and zeaxanthin are antioxidants and protect against the damage caused by free radicals.Meso-zeaxanthin is the 3rd component of the macular pigment and is only found at the centre where vision is sharpest. Meso-zeaxanthin is obtained by the conversion of lutein to meso-zeaxanthin in the macula. It is not found in a typical diet. Meso-zeaxanthin is being recognised as a more powerful neutraliser of free radicals than either lutein or zeaxanthin.Vitamin B2 (riboflavin) helps maintain normal vision.Macushield Original Chewable in a once-a-day, bilberry-flavoured chewable supplement to support eye health.
