Active Ingredients in AndorraLife's OptiVision:

Vitamin A
Helps the surface of the eye, mucous membranes and skin be effective barriers to bacteria and viruses, reducing the risk of eye infections, respiratory problems and other infectious diseases.

A lack of vitamin A causes the cornea to become dry, leading to clouding of the front of the eye, corneal ulcers and loss of vision. Vitamin A deficiency also causes damage to the retina, which also contributes to blindness.

Vitamin C (also known as ascorbic acid)
A water-soluble vitamin and a powerful antioxidant. Abundant in fruits and vegetables, Vitamin C helps the body form and maintain connective tissue, including collagen found in the cornea of the eye.

Vitamin C also promotes healthy bones, skin, and blood vessels, including the delicate capillaries in the retina. Studies suggest long-term consumption of Vitamin C may also reduce the risk of forming a cataract, as well as the risk of vision loss caused by macular degeneration.

Zinc
Helps the body absorb Vitamin A as well as many antioxidant enzymes used by the body to reduce the number of free radicals. Zinc has been shown to protect against macular degeneration and night blindness.

Selenium
Helps the body absorb Vitamin E. Good food sources of selenium include Brazil nuts, oysters, and other seafood.

Lutein and Zeaxanthin
Two key nutrients which are vital to protecting the eyes. In nature, Lutein and Zeaxanthin appear to absorb excess light energy to protect plants from too much sunlight. In humans, both Lutein and Zeaxanthin are highly concentrated in the macula of the eye and responsible for filtering out visible blue light, which may cause damage to eye tissue.

Lutein and Zeaxanthin also contribute important antioxidant functions in the body. Along with other natural antioxidants including Vitamin A, Vitamin C, and Vitamin E, these xanthophylls guard the body against the damaging effects of free radicals, which are unstable molecules that destroy cells and play a role in many diseases.
