Eye Health Supplement And Nutrients Importance

Introduction to eye health
The eyes are important and complex structures in the human body. They enable an individual's sense of sight, by transmitting light signals to the brain. When exposed to light, the eyes undergo a complex series of chemical reactions. These reactions allow the eyes to absorb light, process color and transmit nerve impulses to the brain via the optic nerve. This process enables humans to see things.

However the eyes are very sensitive instruments which become damaged if they are exposed to too much light or other toxic substances (e.g. smoke in the environment, chemicals in cosmetic products). They are also dependent on a range of vitamins and nutrients to maintain their proper function (e.g. Vitamin A deficiency is the leading cause of preventable blindness amongst children in developing countries). There are therefore many ways in which the eyes can potentially be damaged, but also many preventative measures an individual can take to protect against eye diseases and/or disorders.
 

 What to eat for bright healthy eyes

• Eat plenty of fruit and vegetables, which contain a wide range of vitamins and minerals which protect the eyes. For example leafy green vegetables (e.g. spinach) are a good source of Vitamin A and citrus fruits and tomatoes are rich in Vitamin C;
• Reduce fat and increase fibre intake, to prevent diabetes, a metabolic condition which commonly leads to diabetic eye disease;
• Maintain a healthy body mass index to prevent diabetes.

To maintain healthy vision and reduce the risk of developing degenerative eye diseases, your eyes need sufficient amounts of various nutrients. Ideally these nutrients are provided by a healthy and well balanced diet. Various herbs, vitamins, minerals and other nutrients have been intensively researched for their role in supporting vision health, especially age-related macular degeneration, glaucoma, cataract, night blindness and low vision. Herbs and nutrients have also been identified to address issues such as dry eyes and eye fatigue. Eye fatigue is often caused by modern living which involves long hours in front of visual display terminals.

The dryness of eyes is caused by an imbalance in the tear-flow system of the eye. Eyes contain special glands that produce tears. Tears are a combination of special proteins, antibodies, mucus, oil and water. Antibodies in tears help protect eyes against infections, oil helps in lubrication and water gives a moist sensation to your eyes.

The symptoms of dry eyes include itching, redness, pain, light sensitivity, blurred vision and gritty sensation. There are numerous factors that may lead to dry eyes. They include aging, menopause, diseases that affect the ability to make tears, eye diseases, structural problems with eyelids, side effects of certain medications, collagen vascular diseases and environmental conditions such as heat.

Dry eyes can be treated with artificial tear drops, permanent punctual occlusion and surgery. There are numerous prescription eye-drops available on the market, which help your eyes increase their own tear production. Other medications such as tropical steroids and ointments can also be used to keep dry eyes lubricated. You can also use a supplement that helps maintain the health of your eyes. It is also advised therefore to consume an effective broad spectrum, antioxidant and one-a-day multinutrient tablet that contains vitamins A, B-complex, C, D, and E minerals. Vitamin A helps maintain the health of your eyes and skin. B vitamins help release energy from food and boost your immune system. Vitamins C and E act as antioxidants and help destroy free radicals in your body. Vitamin D strengthens your bones and helps absorb calcium.

Important Nutrients For Vision Health

The human body is a complex organism and most nutrients perform many different tasks in maintaining its general health.

To prevent the slow degradation of the eyes, it is essential to consume certain nutritional and dietary supplements for eye health. The best supplements for eye health are:

1.Vitamin A: Vitamin A is required in large doses to ensure proper functioning of the retina, especially at night. Deficiency of vitamin A may cause ocular disorders like Xeropthalmia or night blindness. Vitamin A also plays a vital role in preventing dryness in the eyes.

2.Vitamin C: A powerful antioxidant that protects your body against oxidative stress. Research indicates that oxidative stress in the eyes can lead to various eye conditions including dry eye disease, cataract, glaucoma and age-related macular degeneration. Some foods that are rich in vitamin C are red pepper, kiwifruit, parsley, wild potato, broccoli, orange and blackcurrant.

3.Vitamin D: Research indicates that vitamin D might play an important role in reducing the risk of age-related macular degeneration. Important sources of vitamin D are fish liver oils, eggs, sardines, tuna and salmon.

4. Vitamin E: Also a powerful antioxidant that helps protect against oxidative stress. Foods containing vitamin E are nuts, spinach, tomato, mango, broccoli and olive.

5. Lutein: A highly essential supplements for eye health, lutein forms a protective shield and prevents formation of cataracts as well as macular degeneration in the eyes. This eye health supplement can be found in spinach, tomatoes, squash, and carrots.

8. Flavonoids (bioflavonoids): Pigments found in many plants and vegetables with beneficial antioxidant effects.

9. Selenium: Selenium is an eye health supplement that is a good source of natural antioxidants and can be easily consumed as a supplement. It can be found in Brazil nuts.

10. Chromium: A healthy level of chromium in the body helps maintain balanced interocular pressure in the eyes. It can be easily obtained from onions and tomatoes.

11. Zinc: Zinc is present in extremely high concentrations in the retina and is a good antioxidant. It helps to maintain proper eye functioning.

12. Copper: The intake of a minimum 2 mg of copper in natural or artificial supplements can enhance the functioning of the antioxidant enzymes in the eye. Whole grain cereals, legumes, and oysters are rich in copper.

13. Acai Berry: This natural supplement in the diet helps balance ocular pressure.

14. Manganese: Wheat germ, nuts, and seeds are the richest source of manganese and can enhance the ocular functions of the eye.
