　　1、多吃些有营养的食物可有效保护眼睛 　　1.1、维生素a和胡萝卜素 　　缺乏维生素a,人体从亮到暗的适应能力就会下降,此外,还会导致眼睛干燥、转动不灵,严重者甚至起白斑、角膜软化或溃疡。 　　补充来源:肝脏、蛋黄和全脂奶。植物性食品当中的胡萝卜素可以在体内转变成维生素a,因此也是补充的好来源。各种深绿色叶菜和橙黄色蔬菜、水果都含有胡萝卜素。它们的颜色越深,胡萝卜素含量就越高。 　　1.2、维生素b族 　　维生素b2被称为“美目维生素”,缺乏这,眼睛容易疲劳、怕光、流泪。此外,维生素b6、泛酸等b族维生素也能帮助眼睛消除疲劳。 　　补充来源:鸡蛋黄、牛奶、动物内脏、瘦肉、豆类、各种粗粮、全麦食品等。 　　2、让眼球做运动可有效缓解眼睛疲劳 　　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。 　　1、显示器 　　电脑显示器是电脑使用者要经常面对的，所以显示器光源的合适与否时至关重要的。因此，可依个人习惯选择一个适合的显示器。为了减少辐射也可以考虑使用lcd(液晶显示器)。一般来讲显示器的辐射主要来源于显示器背面电子元件辐射，因此不建议办公桌以面对面或者前后顺序摆放，以免显示器背面对人，造成对他人的辐射伤害。 　　2、刷新率 　　显示器刷新率的高低和保护眼睛也有很大的联系。低刷新率会使眼睛很快疲劳，无法长时间工作，一般来说，85hz以上对人眼的伤害较小。一些名牌显示器，在安装好驱动程序后就可以在“显示属性”的“设置’页中点击“高级”按钮，然后在“适配器”中设置刷新率，如果显示器能够承受，设置得越高越好。但是一些显示器的驱动程序或显示器本身无法支持较高的刷新率，所以一般用户的刷新率设置在75hz即可。以免调高后屏幕被刷成黑屏，影响使用。 　　3、软件 　　紧张的工作往往会使人过分投入而忘记了休息，这会使眼睛深度疲劳，还有一些电脑游戏爱好者，痴迷于游戏中而忘记了保护眼睛，视力的下降当然是必然的。所以建议大家不要过长时间沉迷于电脑游戏或观看影视节目等，注意适当休息，选择其他的娱乐方式放松心情。 　　茉莉*花茶 　　黄芪10克，茉莉*花0.5克，加85摄氏度开水浸泡一小时。可预防电脑辐射影响人体的循环、免疫、生殖和代谢功能，减少电磁波诱发癌症的机会。 　　仙灵脾玫瑰花茶 　　仙灵脾10克，玫瑰花1克，加85摄氏度开水浸泡一小时后饮用。可预防电磁波导致男子精子质量降低，妇女荷尔蒙分泌不正常，还可以预防由电磁波引起的自然流产和胎儿畸形等。 　　白茶 　　酸枣仁10克，白菊花3克，加85摄氏度开水浸泡一小时后饮用。可预防由于电磁波辐射引起的头痛、心悸、失眠，部分女性经期紊乱、心动过缓、心搏血量减少、窦性心律不齐、白细胞减少、免疫功能下降等。此外，还可以减少电磁波辐射加重高血压、心脏病以及痴呆症发生的几率。 　　子茶 　　枸杞子10克，密蒙花3克，加85摄氏度开水浸泡一小时后饮用。可预防由于过高的电磁辐射对视觉系统造成影响。如视力下降、干眼症、白内障等，以及严重时导致的视网膜脱落。 　　生地栀子花茶 　　生地10克，栀子花3克，加85摄氏度开水浸泡一小时后饮用。可预防由于电磁波导致未成年人钙离子剧烈流失而引起的骨骼发育异常，以及耗伤肝血而引起。 　　1、多吃菠菜眼睛“亮” 　　眼睛是人体最辛苦的器官之一,因此特别容易因为辛苦工作而疲劳、衰老的眼睛也需要通过食物补充营养。近日,英国曼彻斯特大学的一项研究证实,菠菜是叶黄素的最佳来源之一,而叶黄素对于预防眼睛衰老导致的“视网膜黄斑变性”十分有效。 　　2、眼睛干涩吃荠菜 　　荠菜被称作春菜,别名野荠、地菜、护生草、鸡心菜,生长于田野、路边及庭院,荠菜有清热止血、清肝明目、利尿消肿之功效。《名医别录》言其“主利肝气,和中”;《食经》言其“补心脾”;《陆川本草》言其“消肿解毒,治疮疖,赤眼”。荠菜含有大量的胡萝卜素、b族维生素和维生素c,钙、铁含量也较高。与春天常见蔬菜相比,荠菜的草酸含量相对较低,所以荠菜中的钙、铁等物质相对也更易被人体吸收。 　　3、眼睛疲劳吃甘薯 　　为了增强肝脏和肾脏和机能,除了注意防止过量饮酒和过度疲劳之外,还可以通过摄取有益的食物来加以解决。这里面最有代表性的食物就是甘薯。甘薯具有“补中益气”的作用,能提高消化器官的机能,滋补肝肾,对机体的衰弱也有恢复效果。 　　4、蛋黄越黄对眼睛健康越好 　　蛋含有丰富的蛋白质、脂肪、卵黄素、卵磷脂、维生素和铁、钙、钾、叶黄素和玉米黄素等人体所需要的矿物质。蛋由蛋壳、蛋黄、蛋白和蛋系带等部分所组成,分别具有不同的营养价值,其中蛋黄营养价值最高的。 　　1、如果觉得眼部浮肿，将一茶勺的盐溶于一杯暖水中，把棉花浸湿后压干水分，敷在眼睛上数分钟，就能有效减低浮肿。 　　2、清晨起床后，喝一大杯温热的柠檬水，可以消除体内毒素，预防眼部松弛。 　　3、若是前一晚喝太多水导致眼部浮肿，可以先用冷水洗洗脸，然后用冷毛巾敷眼睛;若是前一天晚上喝酒或熬夜造成眼部浮肿，应该用温毛巾覆盖眼部，以促进眼部血液循环，缓解眼部肌肉疲劳。 　　4、挑选适合自己的眼霜质地很重要。一般，膏状的眼霜营养丰厚，眼部啫喱则侧重于补水。眼肿是因为眼部水分聚集，肌肤难以吸收，如果再补水，只会令情况更糟。所以在眼肿的日子，一定要选用有消除浮肿功能的眼霜。 　　10：00 a.m. 　　工作的间隙，做一些简单的眼部运动，舒缓紧盯文字造成的眼部疲劳。简单的几个动作，就可以让你僵了的双眸焕然一新，随时以靓丽的姿态接受屏幕的考验。 　　1、头部保持不动，只移动双眼，尽量向上望，5秒后转向下再望5秒。 　　2、眼睛向左望，5秒后再转向右望。 　　3、从左至右慢慢转动眼球，重复5次。 　　4、从右至左慢慢转动眼球，重复5次。 　　2：00 p.m. 　　吃过午饭，略做休息后，做个简单的眼部按摩，帮助眼周血液流畅地循环。 　　1、用中指和无名指轻按眼眶，舒缓眼部组织。 　　2、由鼻梁处开始，用中指轻柔地按压眼睑，由内眼角按转至眼尾。　　打开电脑设置对于许多人来说是一个基本的技巧。它可以让你进入各种控制面板，包括网络设置、音量控制、显示设置等等。然而，如果你是个新手或者不太了解电脑系统，可能会找不到如何打开电脑设置的方法。 　　在大多数Windows系统中，可以通过按下Win按键 + I来快速打开“设置”界面。只要同时按下这两个按键，就能够弹出此界面。如果你的电脑没有安装Win按键，可能需要手动打开设置界面。 　　如果你的电脑没有Win按键或者无法使用Win按键 + I打开设置界面，可以在Windows菜单中寻找“设置”选项。打开Windows菜单，找到设置图标。如果你找不到“设置”图标，可以在搜索框中输入“设置”关键词，系统会自动搜寻设置选项并将其显示出来。 　　如果你想要找到更多的电脑设置选项，可以通过控制面板找到。在控制面板中，可以找到更多的系统设置选项，例如更改屏幕分辨率、更改音量、更改时间和日期等设置。要打开控制面板，请先在Windows菜单中搜索控制面板，然后选择控制面板图标。如果你使用的在Windows 10系统，则需要在“设置”中寻找控制面板选项。 　　除了Win按键 + I快捷键，还有其他的快捷键可以打开设置选项。例如，你可以使用Win按键 + X来打开Windows’ Mobility Center，可以在此界面上更改电源、屏幕亮度、音量等设置。而Win按键 + P快捷键可以打开投影设置，可以让你更好地调整屏幕分辨率和扩展屏幕等设置。 　　打开电脑设置可能会因为电脑操作习惯、系统版本等因素而有所不同。如果没有找到快捷的方法，试试手动寻找或者在网上查找相关的教程，相信一定会找到打开设置界面的方法。这是电脑使用过程中十分基本的技巧，掌握好它有助于升级系统设置和操作流程，提高工作效率。　　IT administrators and technical teachers can use the Set up School PCs app to quickly set up Windows devices for students. The app configures devices with the apps and features students need, and it removes the ones they don't need. During setup, if licensed in your tenant, the app enrolls each student device in Microsoft Intune. You can then manage all the settings the app configures through Intune. 　　With Set up School PCs you can: Joins student devices to your organization's Microsoft Entra tenant Enable the optional Autopilot Reset feature, to return devices to a fully configured or known IT-approved state Use Windows Update and maintenance hours to keep student devices up-to-date, without interfering with class time Lock down student devices to prevent activity that aren't beneficial to their education 　　This article describes how to use the Set up School PCs app. To learn more about the app's functionality, review the Technical reference for the Set up School PCs app. 　　Before you begin, make sure that your devices and your school's network are configured with the following requirements: Microsoft Entra ID and Microsoft 365 licenses Latest Set up School PCs app A NTFS-formatted USB drive that is at least 1 GB Student devices must either: Be within range of the Wi-Fi network that you configured in the app Have a wired Ethernet connection when you set them up 　　Apply new packages to factory reset or new devices. If you apply it to a device that's already set up, you may lose the accounts and data. 　　If a device is already set up, and you want to apply a new package, reset the device to a clean state. To reset a device, follow these steps: Open the Settings app on target device Select Update & Security > Recovery In the Reset this PC section, select Get started Select Remove everything 　　Alternatively, you can also select Start > Power icon. Hold down Shift while selecting Restart to load the Windows boot user experience: Select Troubleshoot > Reset this PC Select Remove everything If the option appears, select Only the drive where Windows is installed Select Just remove my files Select Reset 　　This section offers recommendations to prepare you for the best possible setup experience. 　　We recommend you run the IT administrator or technical teacher's device on the same Windows build as the student devices. 　　Check the OS requirements in the Set up School PCs app. We recommend using the latest Set up School PCs app along with the latest Windows images on the student devices. 　　To check the app's OS requirements, go to the Microsoft Store and locate the Set up School PCs app. In the app's description, go to System Requirements > OS. 　　We recommend that you run the Set up School PCs app on a computer that's connected to your school's network. That way the app can gather accurate information about your school's wireless networks and cloud subscriptions. If it's not connected, you need to enter the information manually. 　　Don't use Set up School PCs over a certificate-based network, or one where you have to enter credentials in a browser. If you need to set up many devices over Wi-Fi, make sure that your network configuration can support it. 　　We recommend that you: Configure your DHCP so at least 200 IP addresses are available for your devices. Having available IP addresses allow you to set up many devices simultaneously Configure your IP addresses to expire after a short time, for example 30 minutes. IP addresses free up quickly so you can continue to set up devices without network issues. 　　To set up more than one PC at the same time, save the provisioning package to additional USB drives. Then plug the USBs in at the same time during setup. 　　We strongly recommend that you avoid changing preset policies. Changes can slow down setup, performance, and the time it takes to sign in. 　　The Set up School PCs app guides you through the configuration choices for the student PCs.

This action doesn't change the name in Microsoft Entra ID. If you have Global Admin permissions, you can go to Microsoft Entra ID in the Azure portal, and rename the package there. 　　Select how you want to sign in (Recommended) To enable student device to automatically connect and authenticate to Microsoft Entra ID, and management services like Microsoft Intune, select Sign-in. Then go to step 3 To complete setup without signing in, select Continue without account. Student devices won't connect to your school's cloud services and their management will be more difficult later. Continue to Wireless network 　　In the new window, select the account you want to use throughout setup. 　　To add an account not listed: Select Work or school account > Continue. Type in the account username and select Next. Verify the user account and password, if prompted. 　　Select Accept to allow Set up School PCs to access your account throughout setup 　　When your account name appears on the page, select Next 　　Add and save the wireless network profile that you want student devices to connect to. Only skip Wi-Fi setup if you have an Ethernet connection. 　　Select your organization's Wi-Fi network from the list of available wireless networks, or select Add a wireless network to manually configure it.
