Antioxidants

Antioxidants stabilize the molecules known as free radicals - which, as they accumulate, damage our health in a variety of ways. They include carotenoids, enzymes, vitamins and other nutrients. Learn more about antioxidants here and here

These antioxidants are especially important for vision.

Phytonutrients

Phytonutrients are plant pigments - yellow, red, blue, purple - that come from your food and are essential for good health. Some of them, such as the carotenoids lutein, zeaxanthin, astaxanthin, meso-zeaxanthin, and lycopene are very important for good vision health.

They also include the bioflavonoids quercitin, rutin, bilberry, catechins and epicatechins.

The phytonutrients also include polyphenols, indoles, and isoflavanoids.

Enzymes

Enzymes enhance biochemical reactions that produce essential nutrients and functions in the body and in the functioning of the parts of the eye. Some, such as superoxide dismutase and glutathione are expecially important for vision health.

Vitamins

Certain vitamins, especially vitamins E and C are considered to have antioxidant capacity, especially in combination. Other vitamins such as the B vitamins are not antioxidants, but they are important for good vision health.

There are some vitamin-like nutrients which behave like antioxidants. They include Alpha Lipoic Acid and CoQ10
