myopia? Is the distant images are not clear. Usually in reading, writing, close work, the myopia of the balance between regulation and vergence abnormalities, may induce strabismus, affect the appearance and cause discomfort. High myopia not only hereditary, and retinal detachment, vitreous liquefaction, amblyopia and other complication rates compared with emmetropia were significantly higher. Glasses, although the correction of myopia vision, but still give life, the work of the inconvenience, but also indirectly affect the physical and mental health of young people.
in accordance with the incidence of nature, can be short-sighted divided into congenital myopia (also known as pathological myopia) and of acquired myopia (ie, regulatory myopia). By inherited congenital myopia, often since childhood onset, a higher degree of intervention means poor. Of acquired myopia, caused by poor study habits and living environment. So, prevention of myopia, what can I do?
attention to eye health
read, write when you sit up straight and not excessive forward head, the distance and the book should be maintained at more than 30 cm. The lighting should be moderate when reading is too strong, too dark are detrimental to the eyes. Can be summarized as “three” “four” “five”.
the “Three Ones”: reading, writing, eyes with the desktop to maintain the distance of one foot; the body and the desk to keep the punch distance; handshake writing hand and the tip to keep an inch (3.3 cm ) distance.
id=”content”> “four”: the position of the read and write correctly; a lesson to the outdoor activities and overlooking; doing eye exercises should seriously; eye relax thoroughly.
“five no’s”: under dark or light to read and write; not in bed reading when the car or walking; not see the writing is too small, too close, not printing clear reading; not pale pencil homework; a long time watching TV, computer or close homework.

Physical exercise can enhance the body, the eyes as part of the body, can also benefit from it.
attention to diet and nutritional supplements
the three nutrients (protein, sugar and fat) should be comprehensive and balanced intake of vitamins and trace elements, which maintain the eye morphology, development, improve the sensitivity of the optic nerve cells, excited sex plays an indispensable role. The following is a brief rich eye of the beneficial nutrients in food.
protein: fish, milk, eggs, soybeans.
vitamins: vitamins in the body can not synthesize and must rely on the food supply. Vitamin A and vitamin D in the liver, soy protein, more cod liver oil content. B vitamins are found in lean meat, yeast, peanuts and corn and other coarse grains. Vitamin C is abundant in fresh fruits and vegetables.
trace elements: animal bone, rich in calcium and phosphorus, but are not readily absorbed by the body. Milk, eggs, fish, shrimp, lean meat, whole grains, seaweed, kelp, rich walnut content.

In addition to attention to diet and nutritional supplement above, but also to avoid excessive intake of sweets. Rich in sugar in the sweets, too much sugar, on the one hand, will result in excess nutrients obesity, on the other hand, may also cause vision loss. Due to sugar consumption in vivo metabolism of B vitamins, and lower calcium content, the eye and optic nerve cells development.
