上班族电脑族如何保护眼睛

上班族电脑族如何保护眼睛

上班族电脑族如何保护眼睛健康,甩开眼镜的困扰更是一个火热的社会议题。

郑州普瑞眼科医院的蔡文全主任介绍说,其实护眼很简单,只是贵在坚持。

1.让眼球做运动如果盯着电脑屏幕已经一小时了,你需要做一些眼球运动来缓解眼睛疲劳。

例如,向上望,同时呼一口气,再将视线移回中间,吸一口气,如此重复三次,最后再继续进行下侧、左侧及右侧的相同动作。

2.忙里偷闲眨眨眼眨眼动作可以促进眼睛分泌泪水,并将含很多成分的眼泪均匀涂于眼球表面,保持眼部湿润。

很多人因为太专注于工作,长时间盯着电脑屏幕忽视了眨眼睛,导致眼睛干涩不适。

忙里偷闲,眨几下眼睛,有助于清洁眼表面,也相当于给眼睛做一次按摩。

3.上班时保持间歇休息蔡文全主任提醒职业女性如果连续使用电脑6~8小时,应每隔1~2小时休息一次,让眼睛离开电脑10~15分钟;工作1小时后最好离开电脑屏幕,注视远方目标,直到清楚后再维持10几秒钟。

4.坚持按摩解疲劳看资料时或开会间歇,用双手大拇指轻轻揉按眉头下面、眼眶外上角处;也可用食指和中指指腹在眉弓处由内向外轻推至太阳穴轻按,重复5~6次。

长期坚持不仅可以缓解眼睛酸涩疲劳,还有助于视力的改善。

5.工作忙碌吸口气吸口气也会对护眼有帮助吗?当然。

据调查,很多人因为太专注盯着电脑,本能地使呼吸速度变缓,而吸气是可以加速血液循环的,可以缓解眼睛疲劳。

6. 每隔一段时间休息一下7. 如果你不能离开你的座位,那就靠在椅背上,闭上眼睛,放松8. 在漫长的面对电脑的时间里间断的做一些不重要的活儿9. 做一些简便有效的伸展放松运动10. 在显示器一旁放个台灯当你的桌面光源,这样你的眼睛不会太累11. 如果你坐在窗子边上,拉上或调整窗帘以便阳光不要直射到你的显示器上12. 避免在光线不好的屋子里工作13. 买一个适合工作的灯,不仅可以提供合适的光线,也可以减少炫光14. 工作台上的植物可以增加空气湿度,减少灰尘15. 植物还可以保持眼睛湿润16. 如果你的显示器是CRT,注意刷新率17. 用纯平而不是球面显示器18. 根据光线、环境设定最的舒适显示方式19. 字体大小同样也要合适20. 眼睛与显示器保持要保持一定的距离21. 戴一个防强光的眼镜22. 如果眼睛总是不断的调整“焦距”,很快就会累的23. Courier, New Courier等字体适合程序员24. 图片/Web设计师要用最高清晰的显示器,如果使用的是Windows + LCD,最好启用ClearType25. 定期做视力测试。

居家护眼小妙招作文英语英文:As someone who spends a lot of time in front of a computer screen, I know how important it is to take care of my eyes. Here are some tips I use to protect my eyes at home:1. Take breaks: Every 20 minutes, look away from your screen and focus on something at least 20 feet away for 20 seconds. This is known as the 20-20-20 rule and can help reduce eye strain.2. Adjust lighting: Make sure your room is well-lit, but avoid harsh overhead lighting that can cause glare. Use task lighting instead, such as a desk lamp.3. Use a blue light filter: Many devices now have a blue light filter option that can help reduce eye strain. Turn it on if you're going to be using your device for anextended period of time.4. Blink regularly: When we stare at screens, we tend to blink less often, which can cause dry eyes. Make a conscious effort to blink regularly.5. Wear glasses: If you wear glasses, make sure your prescription is up to date. If you don't wear glasses, consider getting a pair of blue light blocking glasses.These are just a few tips that have helped me take care of my eyes at home. Remember, it's important to take breaks and give your eyes a rest throughout the day.中文:作为一个经常在电脑屏幕前工作的人,我知道保护眼睛的重要性。

Removed_视力恢复奇穴——明眼穴

视力恢复奇穴——明眼穴1按摩明眼穴,耳聪目明这是一位60多岁的师兄和我分享的,他原有老花及近视,做这个穴道按压半年后去验视力已达1.2,现在他已不带眼镜。

有空就按压明眼穴。

工作离不开电脑的人更需要这个妙方!祝您健康!舒缓眼睛疲劳的妙方明眼穴上了年纪。

容易老花眼,试试看明眼穴的按摩,保证您会耳聪目明。

工作离不开电脑的人,需要这个妙方!假如我们常常感到眼睛疲劳,但又不是睡眠的时间,这时我们可以利用穴道按摩法,来舒缓眼睛疲劳的症状。

在我们的拇指上有三个相邻接的穴道,分别是明眼、凤眼、大空骨(如上图)。

明眼、凤眼能够改善眼睛疲劳和急性结膜炎,大空骨则可改善一切有关眼睛的症状。

平时眼睛容易疲劳的人,每天要刺激这三个穴道两次。

刺激的方法是,用另一手的拇指和食指夹住,以拇指的指甲分别对着三个穴道施予刺激,只要以稍微感觉到疼痛程度的力气来指压即可。

这是项简单的按摩方法,当工作的休息时间,或是等车的空档,任何时间均可自行操作。

眼睛疲劳往往不容易入睡的人,如果施予上述的刺激来消除眼睛的疲劳,便可轻易入睡,以上的方法还可以抑制老人性的白内障。

希望大家天天健康!中医药学是一个伟大的宝库,应当努力发掘,加以提高。

前人的宝贵经验值得借鉴学习,尤其是八十年代以前的资料,几乎没有功名利禄的水分,医风纯朴,其真实性、实用性、可靠性均很高。

针刺治疗球后视神经炎21例的临床疗效观察重庆市第一中医院眼科,针灸科前言 球后视神经炎,在眼科临床上是一个比较常见的疾患,本病的主要特征是视力障碍,所以患者均以视力减退影响工作和学习才来就诊。

但是很遗憾的。

尽管这个病发现了很久,可是直到现在还没有肯定它的病因,也还没有令人满意的疗法。

因此作者等认为积极钻研祖国医学发掘宝藏寻求对策、是有现实意义的。

我国先民眼科,也和其他各科一样,起源和发展均是很早的。

根据河南省安阳县发掘的殷墟卜辞甲骨,说明在公元前14世纪已有眼病息者的记载,(注一)在我国的第一部医书——内经里,关于眼的解剖已能区分为瞳子(瞳孔)黑眼,(角膜)白眼(球结膜),眼肌,内眦和外眦等。

可以帮助眼睛不被晒 的英语

可以帮助眼睛不被晒 的英语

可以帮助眼睛不被晒的英语In the summer heat, when the sun shines brightly and the temperatures soar, it's essential to protect our eyes from the harmful ultraviolet (UV) rays. UV radiation, invisible to the naked eye, can cause significant damage to our ocular health, leading to various eye problems such as cataracts, macular degeneration, and even skin cancer around the eyes. Therefore, it's crucial to take proactive measures to safeguard our vision.One of the most effective ways to protect our eyes from UV rays is to wear sunglasses that offer sufficient protection. When selecting sunglasses, it's important to look for ones that block both UVA and UVB rays and have a high UV protection factor (UPF) rating. Additionally, make sure the sunglasses fit comfortably and snugly, blocking out as much sunlight as possible.Another crucial aspect of eye protection is to wear a wide-brimmed hat when outdoors. This helps shield the eyes from direct sunlight, reducing the risk of UV damage. Hats with a wide brim not only protect the face and neck but also provide additional shade for the eyes.When spending extended periods outdoors, it's advisable to seek shade whenever possible. Standing under trees or using umbrellas can help reduce the amount of sunlight exposure to the eyes. Additionally, avoid being outdoors during the peak hours of the day, when the sun's rays are the strongest.For those who spend a significant amount of time outdoors, consider investing in special eyewear designedfor outdoor activities. These glasses often feature polarized lenses that reduce glare and improve vision in bright light conditions. They are also designed to withstand impact and are suitable for sports like cycling, hiking, and fishing.In addition to physical measures, it's also essential to incorporate dietary changes that can help protect the eyes from UV damage. Foods rich in antioxidants, such as leafy green vegetables, carrots, and citrus fruits, can help neutralize the harmful effects of UV radiation on the ocular tissue.Lastly, regular eye exams are crucial for monitoring any changes in vision or ocular health. During these exams,ophthalmologists can detect early signs of eye problems caused by UV damage and recommend appropriate treatment or management plans.In conclusion, protecting our eyes from the sun's harmful rays is essential for maintaining ocular health and preventing vision loss. By taking proactive measures such as wearing sunglasses, hats, and seeking shade, we can reduce the risk of UV damage and enjoy the outdoors safely. **保护眼睛免受阳光伤害**在夏日炎炎、阳光炽热的季节,保护眼睛免受紫外线(UV)的有害辐射至关重要。

Many people spend several hours a day staring at computer monitors, smartphones, tablets, and other electronic devices. Prolonged screen time can lead to eye strain, dry eyes, and even long-term vision problems. Therefore, it is essential to adopt healthy habits to safeguard our eyes.One effective way to protect our eyes is by taking regular breaks from screens.

建议将电脑屏幕放置在与眼睛平行的位置,保持头部和颈椎的中立姿态,这样可以减轻颈椎压力,降低眼睛疲劳。

2.调整屏幕亮度和对比度电脑屏幕的亮度和对比度设置对眼睛的舒适度至关重要。

亮度过高或过低都会对视力产生不良影响。

建议将屏幕亮度调至与周围环境相适应的水平,并适当调节对比度,以减轻眼睛的负担。

3.定时休息长时间连续使用电脑会使眼睛长时间注视同一距离,容易造成眼肌疲劳。

因此,要定时休息,每隔一段时间强制自己离开电脑屏幕,进行眼睛放松运动。

例如闭上眼睛做深呼吸,转动眼珠,或者凝视远处的景物,都可以有效缓解眼睛疲劳。

4.眼保健操眼保健操是一种简单有效的缓解眼睛疲劳的方法。

可以在工作学习过程中,每隔一段时间进行简单的眼保健操。

例如:闭眼深呼吸,眼珠上下左右转动,或者用手掌搓热后覆盖在眼睛上,做热敷保护。

5.绿色植物装饰在室内放置一些绿色植物,可以有效缓解眼睛疲劳。

绿色具有舒缓眼部压力的作用,而且可以提供新鲜氧气,改善空气质量,增加室内湿度,减少电脑辐射对眼睛的伤害。

6.远眺窗外景色长时间盯着电脑屏幕,眼睛对屏幕上的小字进行高频率的调节,容易引发视觉疲劳。

每隔一段时间,可以站起身来,远眺窗外的景色,让眼球放松,调整视觉焦点,缓解眼睛疲劳。

7.补充营养适当补充眼部所需的营养物质对缓解眼睛疲劳也起到积极的作用。

维生素A、C、E以及锌、硒等微量元素对眼部健康都有着重要的作用。

可以通过均衡饮食,摄入富含这些营养物质的食物,对眼睛进行维护。

防辐射眼镜究竟有用吗?防辐射眼镜的原理 防辐射的防护眼镜,用于防御过强的紫外线等辐射线对眼睛的危害。

镜片采用能反射或吸收辐射线,但能透过一定可见光的特殊玻璃制成。

镜片镀有光亮的铬、镍、汞或银号金属薄膜,可以反射辐射线;蓝色镜片吸收红外线,黄绿镜片同时吸收紫外线和红外线,无色含铅镜片吸收X射线和γ射线。

比如常见的电焊眼镜,对镜片的透光率要求相对很低,所以镜片颜色多以墨色为主;激光防护眼镜,顾名思义,就是能防止激光对眼镜的辐射,所以对镜片要求很高,比如对光源的选择、衰减率、光反应时间、光密度、透光效果等,不同纳米(nm)的激光就需要用不同波段的镜片。

防辐射眼镜特点:镜片为平镜,对视力无副作用。

采用目前世界上高科技真空离子镀膜精制而成,能百分百阻断电磁波射线。

 镜片含抗辐射物质,具有能吸收低频辐射微波,消除电磁波辐射造成的眼睛潜在发热、头痛、疲倦、干涩等不良症状。

对不同光线有不同的穿透吸收功能,能抗反射、防强光,使用者配戴后明显感觉视觉清晰、自然。

随着社会、科技不断发展,电脑已经成为人们生活、工作、学习中必不可少的工具。

然而很多人一坐在电脑前面,常常一坐就是好几个小时,不管你是上网QQ、MSN聊天,不管你是鏖战在魔兽世界、天龙八步、跑跑卡丁车的世界,还是观赏色戒、功夫之王、魔幻手机视频节目,往往到了一段落时,才觉得自己不但腰痠背痛,而且眼睛也跟著疲劳、酸涩起来,再加上冷气房裡的空调,常常使眼睛不自觉的的乾涩、发红,如果常此疲劳不加以改善的话,不但在外观上会有黑眼圈、白眼球佈满血丝等的改变,日久还会造成视力的减退、视神经的不协调等问题。

视客网隐形眼镜专卖的专家提醒大家平常一定要注意健康的用眼,以下是一些注意事项: 首先应该注意与电脑萤幕的距离不可短於30公分,有条件的可以使用防辐射认证的护目镜,避免辐射线对眼睛的伤害。

若眼睛干涩、发痒,先将眼睛闭起来休息个几分鐘,再张开,千万不要用手去柔眼睛。

若无改善就必须就医,因為有可能是其他的感染所致。

平时使用电脑或看书、看报,最好每30分鐘休息个5分鐘,站起来走动一下,或看看窗外都可以,把一直注意近距离的视线拉长。

同时还应该注意日常的眼睛保养: 多喝水:尤其在有空调的办公室中或是房间裡,应特别注意水分的补充,可改善眼睛黏膜乾涩状态。

滴眼药水、生理时盐水、人工泪液:有戴隐形眼镜的人常常会靠这类的眼药水来保护眼睛;有些人则是為了防止眼睛乾涩,也会在药房自行购买一些眼药水来点,但要注意的是药水的来源,最好还是由医生诊断所开出的,比较保险。

因為大部分的眼药水或人工泪液,為了保存方便都会加入防腐剂或杀菌剂,一般人在使用上应该是不会有太大的问题,但若您是过敏性的体质就很难说了。

冷、热敷:在眼睛疲劳的时候可以使用冰敷与热敷交替,但不可冰到或压到眼球,热敷也是一样,一次不超过5分鐘,可以配合眼睛上下左右的旋转,,多做几次,可以改善眼睛周围的血循,对因疲劳造成的黑眼圈也有很好的效果。

平时可多吃些含有B-胡萝卜素的食品,如:红萝卜、木瓜、南瓜、绿色蔬菜等,有些人在办公室会泡些枸杞茶、或是决明子茶,这些都是对眼睛很有帮助的东西。

再有就是可以给眼睛做一些简单的按摩,方法如下: 眼睛闭上,两手食指按住眼头的位置,轻轻沿著眉骨画到太阳穴,对太阳穴稍加用力按。

再由太阳穴往下画到眼头的位置,反覆数次 两手掌互相搓热,眼睛闭上,然后利用掌心部位的热气,轻轻盖住眼球,但勿重压眼球。

两手食指用力压鼻翼两侧凹陷处。

可以在使用电脑时的中场休息时间,给自己来点按摩,对於眼睛的疲劳也很有帮助。

特别适用于电脑工作者,看电视、玩电子游戏机等人士,能有效阻止有害光线损害眼睛,永保你的视力健康。

防辐射眼镜的辨认 由于防辐射镜片表面镀有一层有色的防辐射膜层,膜层有蓝色、绿色、黄金色等。

蓝绿色镀膜层属于普通抗辐射膜层抗辐射效果根据国家检测能达到50%左右,高抗黄金膜层采用的是特殊氧化银元素,根据国家检测效果能达到90%。

  当场戴起来看电脑,看看有那些不同的感觉。

例如:没有配戴任何防辐射眼镜看电脑,就感觉到显示器特别刺眼,略有跳动。

如果配戴了防辐射眼镜后明显感觉视觉清晰、自然。

  据视客眼镜网视光学专家介绍,防辐射眼镜,就是在眼镜的镜片加工过程中,在制作材料中加入化合物介质,再在镜片上贴防辐射膜层,它们从一定程度上可起到一定的滤波作用。

这是因为由于电脑等的辐射是来自于电磁波,这些波是有一定波长和振幅的,化合物介质和防辐射膜就是利用了这个原理,使得镜片前后表面产生的不同波长的电磁波互相干扰,从而抵消一部分辐射。

防辐射眼镜的保养方法眼镜的摘戴 请用双手拿住镜腿沿脸颊两侧平行方向摘戴。

若用单手摘戴会破坏镜架左右平衡,及引起变形。

折叠镜框应从左边开始 大多数的镜框都是按从左镜腿开始折叠设计的,所以如果先折右镜腿,很容易造成镜框的变形。

 旋转方法 如果是暂时性放置眼镜,请将眼镜的凸面朝上。

若将凸面朝下摆放眼镜,会磨花镜片。

擦镜片的方式  使用清洁的专用试镜布,注意务必用手托住擦拭镜一侧的镜框边丝,轻轻拭擦该镜片。

避免用力过度造成镜框或镜片的损伤。

镜片沾灰或脏东西时  干擦容易磨花镜片,建议清水冲洗再用纸巾吸干水份后用专用眼镜布擦干。

镜片很脏时,建议用低浓度的中性洗剂清洗,然后用清水冲洗擦干。

 请使用眼镜盒 不戴眼镜时,请用眼镜布包好放入眼镜盒。

保存时请避免与防虫剂、洁厕用品、化妆品、发胶、药品等腐蚀性物品接触,否则会引起镜片、镜架劣化、变质、变色。

 眼镜变形时 镜架变形会给鼻子或耳朵造成负担,镜片也容易松脱。

建议定期到专业店进行整形调整。

以下是常见的关于防辐射眼镜的疑问(问答内容摘自百度知道)问1:电脑防辐射眼镜如何与普通眼镜进行鉴别?近视镜里也有这种电脑防辐射镜片吗?昨天去眼镜店配电脑防辐射镜,哪些镜片看上去和普通的树脂镜片没什么区别。

销售人员为此做了一个演示:先将一个罩有玻璃罩的仪器通上电,里面立即出现了转动的光环,据说这就是电磁波,随后将防辐射镜片放在转动的光环前面,镜片前的光线扭曲,出现了一个红色的光点,她说镜片将紫外线、电磁波挡在了外面;接着又拿出另外一个镜片挡上去,没有任何反应。

销售人员说,这个是普通镜片紫外线已经穿透了。

不知道这个演示是真是假?答:近视眼镜里面也是有这种防辐射镜片的,你也不必过于在乎工作人员的演示,人家应该不会骗你.建议你把显示器换成液晶的,那样对保护眼睛有好处的,这种眼镜能够防止一部分的辐射,主要是眼睛,但其他部位是起不到作用的,比如脸上的皮肤.时间长了就很容易起色斑,要把握好时间. 其实电脑最大的辐射是来自天键盘,最好的办法就是在电脑旁边放上一小盆仙人掌之类的小植物,因为仙人掌有吸收辐射的效果,我一直用这种方法。

目前来说一直不错。

你也可以试一试。

问2:请问防辐射眼镜有效吗?经常上网,所以想买一副防辐射的眼镜可不知道有没效,身边的朋友也没人用过,想知道如何选购?要注意哪方面?答:所谓的防辐射眼镜,也就是在眼镜的镜片加工过程中,在材料里加入了一些化合物介质,另外再在镜片上贴上相关的防辐射膜层,它们从理论上讲一定程度上可起到一定的滤波作用。

这是因为由于电脑等的辐射是来自于电磁波,这些波是有一定波长和振幅的,化合物介质和防辐射膜就是利用了这个原理,使得镜片前后表面产生的不同波长的电磁波互相干扰,从而抵消一部分辐射。

视客眼镜网专家指出,以上所说的具备特殊防辐射功能的眼镜,以前主要只是特殊行业的人员使用,对工艺要求较高,比如过去在放射科工作的医务人员,戴一种含铅量较高的防射线眼镜,可以有效阻挡X光射线。

但普通的眼镜制造厂家未必具有这种技术,其防辐射效果也很难说。

而且,目前对于用于眼睛保健作用的防辐射眼镜还没有相关的厚度、抗辐射强度等具体的质量检测标准,仅凭厂家单方面宣传,容易造成眼镜市场的混乱及眼镜质量参差不齐。

另外,防辐射眼镜也并不是适合所有的人,尤其是有的孩子戴红色等有色贴膜防辐射眼镜,减少了光的刺激,这样反而不利于视觉发育。

眼睛防辐射小秘诀常饮菊花茶,能清肝明目和防止眼部出现小细纹,菊花茶还能够吸收荧光屏的辐射。

用拇指从眼眶下缘1厘米处向上按摩,找到能够感到轻微酸痛的地方重点按摩,此处是眶下神经和眶下动脉静脉的必经之处,常按摩可以促进血液循环,提高抵抗力,抗辐射,提高视力。

轻轻按压上眼眶内侧凹陷部位3至5分钟,此处是眶上神经和眶上动脉静脉的必经之处,作用如上述。

稍稍用力按压双侧内眼角的凹陷处3至5分钟,以发热为度,此处是内眦动脉和静脉汇集的地方,常按摩,可以提高抗辐射能力。

常按太阳穴,5分钟左右,微微发热为度,常按摩,既可以提高眼睛抗辐射能力,又可以提神醒脑,增进智力。

问3:如何挑选防辐射平光眼镜?经常上网眼睛不舒服,我想买一副防辐射平光眼镜,但去市场上一看傻眼了,有成品境,有现配的,牌子五花八门,价格高低悬殊,质量参差不齐(听说眼镜行业很暴力,所以店越开越多),我不讲究名牌,只求防辐射效果要好,经济实惠的,怎么鉴别它是不是防辐射效果好的,哪个牌子,如何选择?答:防辐射眼镜功效确有,但真假难辨,即使商家能拿出防辐射眼镜的质量检测书,也不能保证消费者拿到的镜片就真的有防辐射功能,因为仅凭肉眼,根本无法判断防辐射的功效,所以经常使用电脑的人还是不要太依赖于防辐射眼镜。

如何减少电脑对眼睛的伤害,视客眼镜网专家给出了建议:首先,用电脑时要保持正确的坐姿。

显示器与眼睛的距离至少要在50厘米以上,显示器的最上方应比视线稍低,显示器位置应在视线以下10-20度之间,这样的一个距离及角度可以使眼球暴露在空气中的面积减少。

每工作1至2小时,休息15分钟,将目光望向远方的物体,并做做眼保健操。

经常眨眼,可以减少眼球暴露于空气中的时间,避免泪液蒸发,切忌“目不转睛”。

睡眠充足,不熬夜,多喝水,多吃各种水果。

看了这么多,大家应该都会了解该怎么样保护自己的眼睛了吧!我还有一个小窍门哦,可以一边玩电脑的时候一边敷一个补水面膜,这样我们的皮肤和眼睛都会变得健康和水灵!有什么问题可以立刻咨询视客专家哦!不要让你的眼睛出现干涉的状态,很不好哦!。
