"My eyes start to smart and become very red in air-conditioned rooms, and also when I work for a long time at the computer..."
Just like the rest of the body, our eyes need nourishment. Eating well supports good health in many ways, and the benefits are far-reaching. When you are watching television or reading, you are using your central vision, which comes from the back of the eye in a region called the macula. The macula has a yellow colour pigment made up of carotenoids. One of these carotenoids, lutein, is an antioxidant, which protects the macula tissue from harmful oxidation by destroying free radicals. The reason this is of such importance is because it is the macula that is responsible for detailed vision.
