Eye protection is an important life project. It runs through our work and life. Let's start from now on, protect the windows of our hearts, and make them clear and bright forever!
Eye nutrition and health care
Eyes are the windows of the soul. Bright eyes allow people to see the colorful world and make their lives more exciting. However, excessive eye use can cause decreased vision and dry eyes. The eye and cornea finish, brightness, sensitivity to things and visual acuity are closely related to nutrition. reasonable nutrition can enhance the eye's Disease Resistance and play a great role in protecting eyesight, to keep your eyes healthy.
The following lists the nutrients that play an important role in the eyes:
Protein
In the retina of the eye, the image is composed of proteins and lacks protein, which may lead to insufficient synthesis of the image and lead to visual impairment. Therefore, you need to "eat" foods with high protein, such as lean meat, fish, milk, eggs, and soy products.
Vitamins
Vitamin A is an important raw material for eye photosensitive substances. Vitamin A is abundant, which can increase the quality of the cornea and make the eyes bright and powerful. Otherwise, it may cause corneal epithelial cells to fall off, increase, and become kernal, the original clear and transparent cornea becomes blurred like glass, and even causes eye diseases such as night blindness and cataract. Foods containing more vitamin A include animal liver, fruit, vegetables and carrots.
Vitamin B1 and B2 are important substances involved in the metabolism of nerve cells, including the optic nerve. They protect the eyelid, conjunctival, and cornea and prevent the formation of Eye Wrinkles. When it is lacking, symptoms such as dry eyes, conjunctival congestion, eyelid inflammation, fear of light, blurred vision, fatigue, and even optic alignitis may occur. Foods rich in vitamin B1 include rice bran, wheat bran, coarse grains, beans, and peanuts. Vitamin B2 is mainly derived from liver, eggs, milk, and vegetables.
Vitamin C is the Main Nutrients of the eye lens. Under the photograph, the lens is susceptible to turbid cataract, keratitis, anterior chamber, iris bleeding. Foods rich in vitamin C include grapefruit, tomato, jujube, kiwi and green vegetables.
trace elements
although the content of trace elements in the human body is less than one thousandth of the weight, it cannot be performed without their metabolism. Four trace elements have a significant impact on the eyes.
zinc can increase the sensitivity of visual nerves. When there is insufficient zinc exposure, the synthesis of cone-like cells may lead to impaired visual quality, thus affecting color discrimination. The highest amount of zinc is contained in oysters, liver, cheese, and peanuts are also rich sources of zinc.
selenium is an Important Trace Element to maintain eyesight. Therefore, it is recommended that you eat more foods, including fish, poultry, cabbage, radish, Leek, and garlic seedlings.
molybdenum is an important component of the iris of the eye. The Iris can adjust the pupil size to ensure clear vision. It is high in soybean, lentils, and radish. When there is not enough molybdenum, it affects insulin regulating function, will make the blood sugar rise, cause the eye lens room water osmotic pressure rise, the increase of power and lead to myopia. Rich foods containing molybdenum include brown rice, beef, mushrooms, grapes and vegetables.
calcium and phosphorus make the cornea tough and participate in physiological activities of the optic nerve. Calcium and Phosphorus Deficiency is prone to optic nerve fatigue and attention dispersion, leading to myopia. Rich foods with calcium and phosphorus, such as pork ribs, meat, dairy products, beans, fresh vegetables and fish, shrimps and crabs.
