My optometrist and ophthalmologist both agree that all three ingredients in Macushield are essential for eye health. I am on my second order of 6 boxes. I will go for an eye exam this month. Then I may know more about effectiveness. The clinical studies I have read are all positive. They state that the Mezo-Zeaxanthin is particularly important to the health of the macula. Be sure you get all three, Lutein, Zeaxanthin, and Mezo-Zeaxanthin.
