Nutritious diet could help to improve your eyesight naturally. Deficiency of certain nutrients often lead to poor vision.
Yellow, orange and dark green colored vegetables:
Beta carotene is a type of phytonutrient found largely in yellow, orange and dark green colored vegetables. It is a precursor of vitamin A. In the human body it is converted into vitamin A.
Vitamin A is extremely beneficial for the health of the eyes. It removes toxins from the eyes and lowers eyestrain. Vitamin A might reduce the risk of cataracts and macular degeneration.
This micronutrient improves your night vision. Deficiency of this essential eye vitamin leads to night blindness. Studies have shown that vitamin A and its precursor beta carotene could protect the eyes from the ultraviolet rays of the sun.
Carrot is one of the best sources of beta carotene. Beta carotene is also found in apricots, pink grapefruits, blueberries, cantaloupes, winter squash, sweet potatoes and dark green leafy vegetables.
Fish oil could help to improve your eyesight. In a John Hopkins University study, researchers have found that at least one serving of fish per week could significantly lower the risk of age related macular degeneration. Macular degeneration occurs due to degeneration of the light sensitive cells of the retina.
Development of new blood vessels behind the retina is often associated with this eye disorder. The fragile blood vessels rupture, damaging the macula. Macular degeneration is one of the major causes of blindness in senior citizens worldwide. Omega-3 fatty acids present in fish oil could prevent this condition.
Sulfur rich foods:
Garlic and onions are rich in sulfur, which is beneficial for the eyes. Sulfur is good for the health of the eye lens.
Foods containing riboflavin and niacin:
Riboflavin and niacin are two members of the vitamin B family, which are essential for healthy eyesight. Riboflavin is found in fish, milk, dairy products, poultry and green vegetables. Niacin could be present in lean meat, liver and whole grains.
Foods containing lutein and zeaxanthin:
Lutein and zeaxanthin are carotenoids found in dark green leafy vegetables, broccoli, peas, corn, zucchini and eggs. They could improve your eyesight and prevent macular degeneration.
