演讲,首先要了解听众,注意听众的组成,了解他们的性格、年龄、受教育程度、出生地,分析他们的观点、态度、希望和要求。掌握这些以后,就可以决定采取什么方式来吸引听众,说服听众,取得好的效果。优质的演讲稿该怎么样去写呢?下面是小编为大家整理的演讲稿,欢迎大家分享阅读。
爱眼日演讲稿300字篇一
早上好
十年前的今天,由卫生部等十二个中央部委联合发出《关于开展“爱眼日”宣传教育活动的通知》,决定每年6月6日为全国爱眼日。所以,我今天讲话的题目是:加强锻炼,预防近视
要预防近视必须了解近视的发病原因。高度近视的父母,其子女几乎100%是高度近视。对于这一类患者来说,改变遗传基因是根本的治疗方法。对大多数近视患者而言属于遗传和环境引起的发病,而且环境因素占到45%以上。所以从环境入手预防近视就变为可能。近年来,从中外学者所进行的动物实验中证明,长期紧张近距离用眼所引起的一系列反射所带来的眼组织的代偿性变化是引起近视的主要原因。长期近距离用眼为什么会引起近视呢?从生物进化和环境因素对人的视觉系统发育的影响中,也可以得到证明。原始人类生存在广阔的大自然中,以巢居穴处,渔猎为生,他们所看到的东西都在远处,他们的视觉适应远处物体来得光线,并能在视网膜上形成清晰的物象,所以远古人都是正视眼。现在的人刚刚出生的时候,眼球仍然多半是接近正视的轻度远视眼,以后随着身体的发育,眼球慢慢增大逐渐变成为正视和近视。
文明在进步,科学在发展,近距离用眼精读的机会不断地增加,尤其是近年来,电脑、游戏机的普及,必然会影响近视的发生发展。请看两组数据:1996年我们学校学生平均视力低下率为32.12%,20xx年我们学校学生平均年视力低下率为41.37%,均高于同时期全国城市小学生平均视力低下率。由此可以看出我们学校学生视力低下呈逐年上升的趋势。怎样预防视力低下已经是一个非常迫切的问题。既然专家们已经论证了近视的主要原因是长期近距离用眼所引起的,那么预防近视就应该反其道而行之。因为学生平时用眼绝大部分是使用近视力。视力分为远视力和近视力,近视力过度强化造成了远视力运动不足,远视力就会退化,看远处的物体就会模糊。所以尽量使眼睛多看远少看近处或远近结合协同锻炼,让自己的远视力得到强化才是预防的关键。每一个同学都应该为自己努力营造一个健康的视觉环境,比如加强锻炼,三要三不要等等。这些内容同学们可以倒背如流。但是请一定遵照执行。在这里我要特别提出的是握笔的姿势,若握笔的手指过于接近笔尖,尤其是拇指过度弯曲,挡住视线,要想看清笔尖在纸面上移动,必须要将头前倾并向左偏斜,并不是握笔的姿势好就能防治近视,但握笔的姿势不好,由于眼和笔尖的距离过近,肯定会多发近视。所以对于刚刚接触笔的低段学生一定要加强握笔姿势的训练,从多年的视力的统计数据中可以看出9岁是眼的屈光度改变的重点年龄,所以预防近视的重点年龄是9岁以后。
很多同学经常问我这样的问题,他们的眼睛是真性近视还是假性近视。从理论上讲,假性近视是由于眼肌的持续疲劳眼的屈光力增强而造成的物象不能在视网膜上而是在视网膜前成像。()所以物象模糊。而真性近视是由于眼的屈光力正常而眼轴长变长,物体同样不能在视网膜上而是在视网膜前成像形成物象模糊。对于大多数视力低下的青少年学生而言,均为混合型近视,因为眼屈光力的加强和眼轴长增加是一个渐变而不是突变的过程,所以,在近视的初期(假性近视)可能既有屈光力加强,又有眼轴长增加,此时眼轴长的改变数值可能很小,不易被检测出来,所以,对于假性近视来说,很可能假性不“假”。假中有真。
有些同学可能要说,现在科学这么发达,激光治疗近视不是很火吗?大不了做个手术就ok了。目前世界上各种各样治疗近视眼的方法都不能从根本上解决发病原因。只是在视线通过的健康角膜上动刀或加压使角膜变形,用来降低屈光度,若从治疗效果和所需要承担的风险来衡量,并不是理想的发展方向。毕竟手术治疗近视眼只有短短的十几年,并且第一批用激光治疗近视眼的患者中,有些已经开始出现视力严重的回退和复视等手术后遗。,科学发展到今天这种程度,还没有哪一种医疗技术可以与近视眼镜相媲美,但近视眼镜使远视力得到提高只起到矫正作用,无论你佩戴多久,仍然是戴上昭昭,去掉昏昏,既无治疗效果也无预防作用。特别需要提出一点,近视眼镜是把近视眼暂时矫正人工正视力,其目的是为了解决看远问题,这种被矫正的人工近视在看近处物体时,反而要比原有近视眼使用更大调节,因而低度近视眼患者戴眼镜看书,有可能使原来的近视度数加深。这一点一定要引起足够的重视。
同学们,眼睛是心灵的窗户,通过这扇窗户,你可以看到一个真实而完美的世界。请重视和爱护自己的视力就象爱护自己的生命一样。不要让你的双眼失去应有的光泽,明亮的眼睛会使你们终生受益。

亲爱的同学们:
大家好!
眼睛是我们认识世界,学习知识,相互交流的重要窗口。如果我们失去了明亮的眼睛,我们的世界将是黑暗的世界。视力的减弱,给我们的学习带来许多的不便。
妈妈时常告诉我要好好保护视力,不要像她小时候那样。妈妈小的时候,由于生活条件较差,又没有对视力的保护给予足够的重视,到中学时已经架上了厚厚的眼镜。对日后的学习和生活产生了很大的影响。
现在,科学进步了,我们的生活条件好了,我们有条件,有能力,更有信心保护好我们的眼睛。只要我们大家努力去做,我相信我们每个人都会有一双明亮澄澈的大眼睛。
首先要养成良好的用眼习惯:保持正确的坐姿,在足够的光线下看书、写字,每隔四十五分钟休息一会,望一望远处,使眼睛得到充分的休息,坚持每天做好眼保健操。其次注意加强营养,多吃一些有益于我们眼睛的食品。含有维生素c的食物对眼睛有益处,因此每天都要注意多吃一些含有维生素c的食物哦!
同学们让我们互相交流,共同保护好我们的眼睛,好好学习,共同迎接新世纪的挑战,争取为祖国建设多做贡献。

爱眼日演讲稿300字篇五
敬爱的老师们,亲爱的同学们:
大家早上好!
同学们,你们知道6月6日是什么日子吗?也许你还不知道吧, 6月6日是爱眼日。今年的六月六日是全国第十八个爱眼日。你知道六月六日爱眼日的来历吗?1992年的9月25日,天津医科大学眼科教授首次向全国倡议,在国内设立爱眼日,并在天津召开了全国爱眼日第一次研讨会。这一倡议受到眼科学界和眼科专家们的响应, 1996年,国家卫生部、国家教育部、团中央、中国残联等12个部委联合发出通知,将爱眼日活动列为国家节日之一,并确定每年6月6日为“全国爱眼日”。 我国青少年的视力问题值得关注,据国家教育部、卫生部最新调查表明:目前我国共有4亿多近视眼患者,近视发病率达33.3%,小学生近视率超过25%,初中生近视率达到70%,高中生近视率达到85%,每年以8%的速度增长,居世界第一位,其中青少年是近视“重灾区”。
今天我们演讲的主题就是《爱眼护眼,世界等着你去发现》。
眼睛是心灵的窗户,人人都有一双明亮的眼睛。这双眼睛可以看到五彩缤纷的大千世界,但现在,清晰的视野离我们越来越远。这是为什么呢?这是因为许多同学没有作息地用眼,不顾卫生地擦拭眼睛,不注意距离地看电视、用电脑、看书等等。也许有的同学错误地认为“只要我学习好就行了,视力不好配戴眼镜就行了。“更有的人认为戴眼镜是有知识的象征。但现实生活告诉我们:一旦患了近视,戴上眼镜会给学习和生活带来很多不便。例如在参加体育活动的时候,打破眼镜甚至伤及眼睛到医院做手术缝合是常有的事。戴上眼镜如仍不注意用眼卫生,常会使视力下降加快,形成高度近视,甚至失明。而且患高度近视的同学在将来考大学选择专业和将来工作择业都会受到限制。如果你学习成绩很好,只是因为眼睛近视而被你所钟爱的专业拒之门外,那你将会抱憾终生。
眼睛可以让我们去认识世界,学习知识,如果我们失去了明亮的眼睛,我们的世界将是黑暗的。同学们在日常生活和学习中一定要自觉的注意科学用眼。下面,我向大家提几个建议:
1. 看书写字时眼睛与书本的距离要保持30厘米左右,姿势要端正。
2. 连续书写50分钟后,休息10分钟左右。
3. 不要在光线太强或太弱的地方看书。
4. 走路或乘车时不要看书。
5. 不要躺在床上看书。
6. 坚持做好眼保健操。
同学们你们还知道吗?眼睛是人类感官中最重要的器官,大脑中大约有一半的记忆和知识都来自于眼睛。我们有什么理由不保护眼睛呢?
常言道:冰冻三尺非一日之寒,水滴石穿非一日之功,保护眼睛也不是一朝一夕就能做到的,注意用眼卫生、科学用眼贵在坚持,需要持之以恒,才能预防近视的发生及近视程度的加深。
婀娜多姿的山河,绚丽多彩的万物,一切的一切都需要眼睛来观察,同学们,让我们一起爱护眼睛,世界等着你去发现!

敬爱的老师们,亲爱的小朋友们:
大家好!
我是中二班的左xx,今天我讲话的主题是:我们的眼睛。
小朋友们知道全国爱眼日是哪一天吗?是每年的六月六日。眼睛是心灵窗户,通过眼睛,我们可以看到鲜艳的五星红旗,美丽的风景,还有老师和小朋友脸上灿烂的笑容。
可是,我们眼睛周围,却有五个敌人:
一号敌人是细菌,所以小朋友不要用脏脏的手,或别的脏脏的东西去揉眼睛。
二号敌人是烟,如果身边有人吸烟,你要离他远一点。
三号敌人是干燥,我们可以多喝水打败敌人。
四号敌人是过度日晒,在炎热的夏天,我们尽量不要在太阳底下暴晒。
五号敌人是睡眠不足,小朋友一定要保证充足的睡眠,这样对眼睛才有好处。
此外还应当养成良好的用眼习惯,比如:
不在阳光下看书
不在摇晃的车上看书
不躺在床上看书
看电视、看电脑的时候不能离得太近
时间也不能超过30分钟
用眼一段时间之后,要注意休息
还要多吃蔬菜和水果。
我们的眼睛现在还在发育期间,要多到户外玩耍,接受自然光线的刺激,让眼睛跟我们一起健康的成长。
眼睛是我们很重要的宝贝,小朋友们可一定要好好的保护它哦!
谢谢大家!

老师们、同学们:
大家早上好!
今天我讲话的主题是《保护眼睛》。每年的6月6日是世界爱眼日,今天就是6月6日。当我们抬起头注视着鲜艳的五星红旗冉冉升起时,你们有没有想过:是什么让我们看到了这激动人心的情景?对,是我们的眼睛!
当你牵着爸爸妈妈的手,漫步在林荫小路,观看两边绿草如茵、鲜花盛开时,当你坐在教室里读书、看黑板,看老师的眼睛索取知识时,你是否意识到你是幸运的呢?眼睛是心灵的窗户,拥有一双明亮的眼睛是一件多么幸福的事情。我们每个人小时候都拥有一双明亮的眼睛,拥有过夏夜繁星闪烁的天空。可是渐渐地,由于读写姿势不当,用眼过度,许多人的视力不断地下降,蓝天不再明净,繁星变得一片朦胧。有资料显示,我国眼睛不好的人数居然仅次于世界第一的日本,因此也被称为“中国眼”。我国的盲人达到了500万,占全世界盲人总数的18%;而且每年约有45万人失明,这意味着几乎每分钟就会出现一例新的盲人。我国的近视人数达到了1000万。保护视力刻不容缓,为此,我建议大家做到如下几点:
1、“一好”:认真准确做好眼保健操,注意眼睛卫生。
2、养成良好的读书写字习惯,读写姿势要端正,背部要伸直,颈部保持直立,做到“三个一”,眼离书本一尺远,手离笔尖一寸高,胸离桌子一拳远。
3、“三不”:不躺着看书,不在走路时看书,不在光线太暗或太强的地方看书、写字。
4、看电视和操作电脑时,要保持一定的用眼距离和端正的坐姿。
5、保证充足的睡眠。充足的睡眠是消除疲劳,恢复学习能力的重要原因,也是保持身体健康的主要因素。
6、多做户外运动,经常远眺,使眼睛得到休息,调节视力,解除疲劳。
7、不偏食,多吃奶制品、鱼、蛋、肉等,少吃糖果和含糖高的食品,合理安排我们的饮食结构,从饮食中获取充分的营养物质。多吃蔬菜,尤其是胡萝卜等含多种维生素的食品。
做到以上几点并不难,只要同学们自觉执行,只要老师们随时提醒,我相信,同学们一定会拥有一双更清澈、更明亮的眼睛,一定会拥有一片更广阔、更明净的天空!为了美好的明天让我们一起努力吧!

老师们,同学们,早上好!6月6日也就是这周三,是与大家健康有关的日子,它是“全国爱眼日”所以,今天,我讲话的主题是:爱护眼睛,从点滴做起。
为什么要设立这样一个节日呢?
眼睛是“心灵的窗户”,每个人都想拥有一双明亮的眼睛。然而,统计结果表明,我国约有盲人500多万,低视力者600多万,儿童斜弱视者1000多万。卫生部、教育部的联合调查显示,目前我国学生近视发病率接近60%,居世界第二,而人数高居世界第一。
这意味着,在我们中间,每10个同学差不多就有6个要成为近视患者。
我听到大家一片惊叹声,是啊,这样的一种情形,几乎可以用“可怕”来形容了。
正因为眼睛如此重要,而在我国眼睛疾病又如此严重, 1996年,卫生部、教育部、团中央、中国残联等12个部委联合发出通知,将爱眼日列为国家节日之一,并确定每年6月6日为“全国爱眼日”。
关于爱眼,我们应该做些什么呢?
第一、少看电脑和电视。不是禁止完全不碰,一呢少看,二呢注意休息,让眼部肌肉能有机会放松。有人会问:“我不看电脑电视能做什么呀?”可以多做运动、结交朋友,生活丰富了,我们的收获也会更加丰富。或许你能称为打球高手、游泳健将、钢琴王子、芭蕾公主等等。
第二、做到“三个一”:即手指距离笔尖是一寸,眼离课本一尺,胸口离桌子一拳。每天学校的眼保健操也要坚持做。
第三、饮食也可以帮助大家保护眼睛。胡萝卜是大家熟知的保护视力的食物,番茄、菠菜、蛋黄也很好,最近还有专家发现,甜食是少儿视力下降的罪魁祸首,所以提醒大家控制甜食不要过量。
这些方法其实同学们多多少少都有所了解,在家父母也经常提醒吧。我想贵在坚持,持之以恒地做到这几条,你的眼睛会一直像星星一样闪亮。人们都说:“眼睛是心灵的窗户。”我也送给大家一句话:“黑夜送给我黑色的眼睛,我却用它来寻找光明。”让我们打开心灵的窗花透透气吧,让阳光照进来,让我们的`生活一直美妙!
我的讲话完毕, 谢谢大家!

老师们,同学们:
大家好!我今天演讲的题目是《》。
我们都知道,眼睛是心灵的窗户,是我们人体不可缺少的一部分,试想有一天我们失去了这宝贵的“心灵之窗”,那么我们的眼前将是一片黑暗,再也看不见那美丽的颜色。同样,视力的减弱,也会给我们的学习和生活带来许多的不便。目前,据中国、美国合作开展的防治近视研究项目调查显示,我国人口近视发生率为33%,是世界上近视发病率最高的国家之一。保护眼睛,迫在眉睫,每年的6月6日是世界爱眼日。我们在日常生活中一定要养成良好的习惯,来保护自己的眼睛!
大家一定要把爱护眼睛的要求落实到生活中。为此,我建议大家做到以下几点:
1.始终保持教室内充足的光线,光线不足时要及时开灯。
2.看电视和操作电脑时,要保持一定用眼距离和坐姿的端正。
3.多做户外运动,经常远眺,使眼睛得到休息。
做到以上3点并不难,只要同学们自觉执行,我相信,同学们一定会拥有一双更清澈、更明亮的眼睛,一定会拥有一片更广阔、更明净的天空!
我的演讲完毕,谢谢大家。

爱眼日演讲稿300字篇十六
1992年9月25日,天津医科大学眼科教授王延华与流行病学教授耿贯一首次向全国倡议,在国内设立爱眼日,并在天津召开了全国爱眼日第一次研讨会。1996年,国家卫生部、国家教育部、团中央、中国残联等12个部委联合发出通知,将爱眼日活动列为国家节日之一,并重新确定每年6月6日为"全国爱眼日"。
学生的近视眼是怎样形成的呢?据有关资料报道,青少年近视眼以长期用眼距离过近引起者为多见。青少年眼睛的调节力很强,当书本与眼睛的距离达7—10厘米时仍能看清物体,但如果经常以此距离看书,写字就会使眼睛的调节异常紧张,从而可形成屈折性(调节性)近视,所谓的假性近视。
要想有健康的视力,应做到以下几点:
1、阅读姿势要正确。在阅读时,书本与眼的距离应保持在30—35厘米。阅读时最好采取坐姿,不要躺着看书。因为躺着看书时,不易保持两眼与书本的距离相等,致使两侧眼肌发育不平衡。走路、坐车、乘船和乘飞机时不要看书,因为此时身体的摇晃使20xx年全国爱眼日国旗下演讲稿20xx年全国爱眼日国旗下演讲稿眼睛与书本的距离不定,加重了眼肌的调节负担,容易导致近视眼的发生。
2、书写姿势要正确。写字时两手臂要等长度地放在桌面,一长一短会使身子歪斜;胸部与书桌后缘保持一拳的距离。从而,使眼与书本或作业本保持1尺左右的距离。
3、看电脑、玩电子游戏机和看电视的时间不宜过长,一小时左右就该暂停。
4、定期检查视力,发现有近视,及时采取矫正措施。
5、积极参加文体活动,增强体质,积极防止近视我们经常说眼睛是心灵的窗户,我们只有好好地保护它、呵护它,才能利用它清晰地去了解、观察我们所生活、所热爱的这个世界。所以,我们要时刻提醒自己:"我爱护我的眼睛了吗?" 让我们行动起来,一起保护视力、防治近视,还自己一个清晰世界,感悟美好生活!
谢谢大家!
