How to Protect Your Eyes

First, close distance with the eye time should not be too long, every 40-50 minutes should be a little rest for 3 5 minutes, looking to the distance for a while to reduce visual fatigue. Two, reading and writing, playing computer, maintain the correct posture, the height of the desk and chair should be appropriate, the distance between the eye and the reading material should be kept at about 33 centimeters. Three, whole grains, meat and vegetable collocation, eat more vegetables and fruits, do not eat partial food. Lack of vitamin in food prone to night blindness and dry eye disease, lack of trace elements chromium and calcium in food, easy to suffer from myopia. Four, when reading and writing, the light should be appropriate, should not be too strong or too dark, the light should be shot from the front of the left, so as not to hinder the sight of the hand shadow. The light should be soft, such as incandescent lamp, should be between 25 and 40W, do not recommend reading in the sun. Because LIGHT WEAK AND WEAK HAS DIRECT EFFECT TO PUPIL DILATION, TOO STRONG LIGHT CAN INCREASE EYE TO ADJUST INTENSITY, AGGRAVATING INTENSITY OF EYE LABOR, TIME GREW TO CAUSE MYOPIA EASILY INSTEAD. General table top desk lamp is appropriate with 40 watts below. 5. Avoid reading while walking or reading in a walking car. Because the car is shaking and the body is shaking, the distance between the eyes and the book cannot be fixed, and the burden of the glasses will be increased. If you do this often, you are likely to develop myopia. 6. Take an active part in physical exercise to strengthen your physique. When the eye follows the target, the ciliary muscle relaxes and contracts continuously, as well as the synergistic effect of the extraocular muscle, can improve the blood perfusion of the eye, promote the metabolism of the eye, so as to reduce eye fatigue. And the physical quality is closely related to the occurrence of myopia in children. Children who are malnourished and weak are prone to myopia. 7. Keep doing proper eye exercises. By MASSAGING THE ACUPOINTS AROUND THE EYES TO enhance THE blood circulation of the orbit, improve NEUROnutrition, eliminate the transitional congestion in the eye, achieve the purpose of relieving eye fatigue, is conducive to the prevention and treatment of adolescent pseudomyopia, is a good way of adolescent eye self-care. Eight, eat less candy and high sugar food. Too much sugar will produce a large number of acidic substances in the blood, acid and salt in the body, especially calcium, resulting in a decrease in blood calcium, which will affect the tenacity of the ocular wall, make the axis of the eye easy to elongate, promote the occurrence and development of myopia. Nine, regularly to the eye hospital to check vision, found that the decline should be corrected in time to prevent myopia deepened. 10. Eat less sweets. Because a lot of vitamin B1 is needed when sugar is metabolized in the body, if too much sugar is consumed, vitamin B1 is not enough. Vitamin B1 deficiency can make optic nerve growth and development is affected, and bring about the decline of vision. Excessive intake of sugar will also reduce calcium in the body, so that the elasticity of the eyeball weakened, promote the development of myopia. 1, the light must be sufficient: the light must be sufficient and comfortable, because the light is too weak and the font is not clear, it will look closer and closer. Two, reflect to avoid: desk side SHOULD have lighting device, its purpose is to reduce reflect in order to reduce the damage to the eyes. Three, reading time is not too long: no matter doing homework or watching TV, the time is not too long, to take a break every 30 minutes is the best. Four, SITTING position WANTS UPRIGHT: CANNOT bend OVER HUNchback, more close or prone to do homework easily cause ciliary muscle tension is excessive, then cause myopia. Five, reading distance should be moderate: the distance between the book and the eyes should be 30 cm, and the height of the table and chair should be compatible with the physique, not reluctantly. Six, WATCHING TV DISTANCE is not too close: WATCHING TV should be maintained with the TV picture diagonal six to eight times the distance, every 30 minutes must rest for a while. Seven, sleep is not too little, regular work and rest: lack of sleep is easy to fatigue, easy to cause pseudomyopia.
