近视眼的形成原理,怎样保护眼睛视力?

近视是各种因素的结果,包括以下几点:
1.遗传因素,据报道,父母1方得的近视,儿童的近视已经30%,父母两个得有近视,我的近视超过70%,所以遗传因素是近视的一个更重要的因素 – ,特别是那些凭借高近视和病理近视,遗传因素的比例甚至更大。
Myopia is a result of a variety of factors, including the following points:
1. Genetic factors, according to reports, parents – Fangqi’s myopia, children’s myopia have been 30%, parents are two persuaded with myopia, my myopia is more than 70%, so genetic factors are a more important factor in myopia – , Especially those with high myopia and pathological myopia, the proportion of genetic factors is even greater.

2,长期近距离眼睛 – 载荷增加。动物实验和流行病学数据证实,长期紧张的近视家庭作业与近视密切相关。青年眼球处于增长和发展阶段,调整能力强劲,球体的拉伸大,调节和辐射过程在球体的近距离工作期间,使外部肌肉(主要是内部直线抗眼球的肌肉施加一定的压力,并且眼内压也相应地增加。随着调整和辐条逐渐增加的频率和时间,睫状肌和眼睛肌肉往往是高度张力的,巩膜下的长期机械压缩外部肌肉,球形壁逐渐延伸,轴伸长。
2, long-term close range with the eye – an increase in the load. Animal experiments and epidemiological data confirmed that long-term tense myopia homework is closely related to myopia. Youth eyeballs are in the growth and development stage, the adjustment capacity is strong, the stretching of the sphere is large, the adjustment and radiation of the processes during the near-distance work of the sphere, so that the outer muscles (mainly internal straight muscle) against the eyeball Apply a certain pressure, and the intraocular pressure also increases accordingly. As the frequency and time of the adjustment and the spokes gradually increase, ciliary muscle and eye muscles are often at a highly tension, sclera Under the long-term mechanical compression of the outer muscles, the spherical wall gradually extends, and the shaft is elongated.

3,营养状况:研究发现,更多的糖果将增加近视。目前,随着生活水平的提高,甜宝宝已经逐渐增加,这也可能促进近视的原因,研究发现适当的补充髂蛋白是可以预防近视。
3, nutritional status: The study found that more sweets will increase myopia. At present, with the improvement of living standards, the sweet baby has gradually increased, which may also promote the cause of myopia, the study found that the appropriate supplemental ilcumin is It can prevent myopia.

中小学生的课业繁重,过度用眼用眼疲劳是很多孩子都会出现的症状,那么中小学生应如何做好用眼健康,预防近视
呢?于刚主任给出以下四点建议:
1.注意用眼劳逸结合:所谓劳逸结合,这里特指用眼的”劳”和”逸”,就是在近距离用眼时间久了以后,我们的睫状肌持
续收缩,就会造成调节紧张甚至痉挛,造成眼部疲劳和假性近视。对于儿童和青少年的近视:我们针对近距离用眼疲
劳,解决的方法-个是注意休息,也就是用眼半小时后,我们可以放眼远眺,让我们眼睛内部的肌肉松弛,避免眼部
的疲劳而且减轻近视的发生。
The lessons of primary and secondary school students are heavy, excessive use of eye fatigue is the symptoms of many children, how can primary and secondary school students should use their eyes, prevent myopia?
What is the following four suggestions from the director:
1. Note that it is combined with eye work and rest: the so-called work and rest, this specifically refers to the “labor” and “escape” that uses the eye, it is a long time in the near-distance time, our ciliary muscle
Continue harvesting, it will cause tension or even spasm, resulting in eye fatigue and false myopia. For children and adolescents: we use your eyes for close range Labor, solve the method – pay attention to rest, that is, after half an hour, we can look away, let our muscles inside the eyes relax, avoid eyeFatigue and alleviate myopia.
2.合理应用”药物”:我们知道有一种叫做睫状肌麻痹剂复 方托品卡胺的眼药水,可以让我们的睫状肌麻痹,放松,针对
近视的患者以及调节疲劳的患者我们可以在每天的睡前点眼- -次,放松眼内肌肉。
2. Reasonable application “drug”: We know that there is a kind of eye drops called ciliary muscle paralyzed Fangtukamine, which allows us to be paralyzed, relax, targeted
Patients with myopia and patients who regulate fatigue we can look at your eyes before going to bed every day. – times, relax intraocular muscles.
3.不排斥眼睛保健操:目前虽然没有证实眼睛保健操是否能够延缓近视发展,但是做操孩子能够放松眼睛周围的肌肉以
及促进眼部血液循环,对缓解我们的眼部疲劳还是有益的。
3. Do not exclude eye health exercises: Although there is no confirmation of eye health exercises to delay myopia development, do children can relax the muscles around the eyes
And promote blood circulation, which is still beneficial to alleviate our eye fatigue.
4.四多四少:多做户外活动减少近距离用眼;多放眼远眺少用电视电脑,多吃叶黄素,含粗纤维的食品少吃甜食和含
脂肪高的食品。多-些正确的习惯,少-些不良习惯。
4. More than 4,000: more outdoor activities reduce close to the eye; enjoy more than small TV computers, eat more lutein, eat less sweet food and contain
Fat high food. More – some correct habits, less – some bad habits.
