老师们，同学们，大家上午好！今天我发言的主题是：科学用眼，预防近视。
Good morning， teachers and students！ The topic of my speech is: Use the eye scientifically to prevent myopia.
世界卫生组织的研究报告显示，我国的近视患者高达6亿人，其中中小学生人数超过1亿，近视率近50%，初高中生近视率高达80%。
The World Health Organization's research report shows that there are as many as 600 million myopia patients in our country， of which more than 100 million are primary and secondary school students， the myopia rate is nearly 50%， and the myopia rate of middle and high school students is as high as 80%.
近视会导致眼睛视物模糊、干涩、疲劳，注意力不集中、头晕等，影响我们的正常学习、生活和身心健康。有些专业和工作对视力有严格要求，近视影响升学和择业。近视还会增加视网膜病变的风险，严重的可导致失明。
Myopia can cause blurred vision， dryness， fatigue， inattention， dizziness， etc.， which affect our normal study， life， and physical and mental health. Some professions and jobs have strict requirements on vision， and myopia affects further studies and career choices. Myopia also increases the risk of retinopathy， which can lead to blindness .
为了守护儿童青少年明亮的眼睛和光明的未来，近视防控刻不容缓！习近平总书记连续作出重要指示，要求“全社会都要行动起来，共同呵护好孩子的眼睛，让他们拥有一个光明的未来。”为此，我们也要学习如何科学用眼，预防近视。
In order to protect the eyes and bright future of children and adolescents， the prevention and control of myopia is urgent！ General Secretary Xi Jinping continuously issued important instructions， demanding that "the whole society should take action to take good care of children's eyes and let them have a bright future." To this end， we must also learn how to use eyes scientifically to prevent myopia.
1.远眺是常见易行的眼疲劳缓解方法。双眼可以望向窗外绿色植物、眺望远方。
Looking far into the distance is a common and easy way to relieve eye fatigue.
2.眼保健操可以有效的预防和缓解眼部的干涩酸胀。每天要认真做好眼保健操。
Eye exercises can effectively prevent and relieve the dryness and soreness of the eyes. Do eye exercises every day.
3.足够的白天户外活动时间是预防我们近视的重要措施。应该确保自己每天进行2小时以上的白天户外活动。
Adequate outdoor activity during the day is an important measure to prevent myopia. You should make sure that you are doing outdoor activities during the day for more than 2 hours a day.
4.注意营养均衡，可以多食用胡萝卜、蓝莓等有益于视力的蔬菜水果。
Pay attention to balanced nutrition. We can eat more vegetables and fruits such as carrots and blueberries.
5.养成良好的用眼习惯，避免长时间持续近距离用眼，坚持“三个一”：即眼睛离书本一尺，胸口离桌沿一拳，握笔的手指离笔尖一寸。
Develop a good habit of using eyes， avoid using eyes close for a long time， adhere to the "three ones".
6.长时间、近距离、持续盯着手机、电脑和电视等电子产品的屏幕，是近视的最常见的诱因之一。
One of the most common causes of short-sightedness is prolonged， close and persistent staring at screens of electronic devices such as mobile phones， computers and televisions.
最后，发现自己视物眯眼、频繁揉眼、上课看黑板上的文字或远处物体不清楚时，要考虑发生近视的可能。一旦出现这种情况，应该及时和家长去医院就诊。
Finally， if you find yourself squinting， frequent eye rubbing， class to see the blackboard on the text or distant objects are not clear， to consider the possibility of myopia. Once this happens， you should go to the hospital with your parents in time.
眼睛是心灵的窗户，只有拥有一双明亮的眼睛，我们才能看到这个美丽的世界。同学们，让我们从现在开始：科学用眼，预防近视！
Eyes are the windows of the soul. Only with a pair of bright eyes can we see this beautiful world. Classmates！ let us start from now: use our eyes scientifically to prevent myopia！
