The eyes communicate with the brain through the optic nerve.
As the visual transactions emerge from the optic nerve, they are transported to the brain through a system of fibers which are part of the optic tract.
Vision requires that several systems cooperate with each other to insure that the proper signals reach their destinations. In order to work properly, the muscles, nerves, optic fibers and eye tissue must be properly nourished.
The blood must also be well-nourished, to supply the brain with the nutrients necessary for it to properly function.
VITAMIN A contributes to the health of nearly every tissue in the body and its role in vision is well understood. A modified light receptive form of vitamin A, known as 11-cisretinol, allow a person to see in very low light.
BETA CAROTENE is the preferred source of vitamin A for a number of very important reasons. Beta carotene is non-toxic because the body converts beta carotene into vitamin A only as it is needed. Beta carotene is one of the antioxidant nutrients, much like vitamin C, vitamin E and Selenium.
VITAMIN E, with its antioxidant properties, produces benefits in maintaining eye health. It interacts well with vitamin A and is necessary for epithelial health. The function of the epithalamus, located in the brain’s thalamus, is to pass on nerve signals for the senses and movement.
B COMPLEX nutrients are required for the maintenance of ocular tissue and, in particular, the cornea and optic nerve.
NIACIN is a B-complex nutrient which is necessary for growth, the proper functioning of the nervous system, and the transmission of impulses to the body’s senses.
Other nutrients, while not directly associated with ocular health, contribute to the overall health of the body. This in turn, may affect the health and well-being of the sensory functions. Some of these nutrients include:
VITAMIN D is very important because it participates in healthy bone structure and muscular development.
VITAMIN C has many uses in the body. It increases the absorption of iron, and helps in the production of collagen and is essential for the immune system. Vitamin C is needed for healthy teeth, gums and bones while strengthening the blood vessels.
CALCIUM is a mineral which is necessary for healthy, strong bones and teeth. Other functions of the calcium ion include its influence in blood coagulation, neuromuscular excitability, and transmission of nerve impulses.
MAGNESIUM is essential for the metabolism of potassium and calcium.
SELENIUM preserves tissue elasticity, and works with Vitamin E. Like vitamin A, C, and E it is an antioxidant.
ZINC aids in the digestion and metabolism of phosphorus and protein. Protein is essential for the forming of antibodies, enzymes and hormones.
