中小学生带手机进课堂？不行

In a notice published by the Ministry of Educationin February 2021， elementary and secondary schoolstudents are asked not to bring their cell phonesonto the campus， except when it is approved by theirparents along with a written application form. Instead，establishing public telephones on campus and exploringthe use of electronic student IDs with call functions areencouraged as a way to solve the needs of students andparents’ communication. This is to protect students’eyesight and allow them to concentrate on their studies，as well as preventing addiction to the internet andvideo games， according to the notice. Teachers areasked not to use mobile phones to assign homeworkfor students as well. This decision has been backed bymany netizens in China.

手机虽好，但对学生而言，使用风险也是真的大：损伤视力，让人沉迷于网络和游戏且无心学习。为了解决这些问题，教育部“交出了答卷”：禁止中小学生带手机进校园;确实有需求带进校园的，在父母同意并附上书面申请后可携带，但也不能带进课堂，需要将手机交由学校统一保管;教师也不得使用手机为学生布置家庭作业。这份“答卷”让众多网民给出高分。

关灯玩手机，到底有多伤眼睛？

Staring at a screen continuously for hours on endcauses focusing fatigue. Researchers have found highlevels of looking at a phone or tablet is linked witharound a 30 percent higher risk of short-sightedness，also known as myopia. But when it is combined withexcessive computer use， that risk rises to around 80percent. To avoid this， many eye experts recommendthe “20-20-20 rule”–looking away from your phoneor computer screen every 20 minutes and focusing onan object at least 20ft away for at least 20 seconds.Smartphone blindness happens when people lie on theirside at night， with one eye against the pillow and theother staring at the smartphone screen. While one eyeadjusts to the dark， the other eye gets used to the brightlight of the high-resolution screen.

連续数小时盯着屏幕，你将体验到聚焦性眼疲劳。研究发现，长时间盯着手机或平板电脑，患近视的风险将增加约30%，若再过度使用电脑，风险将上升到约80%。如果你还爱在关灯后玩手机，那么侧躺着的你，会体验到“智能手机眼盲症”，因为靠着枕头的眼睛适应了黑暗环境，而看手机的那只眼睛则适应了屏幕发出的亮光。现在，你知道使用手机的正确方式了吗？要在明亮的环境里，谨遵“20-20-20规则”，并且秉持“能坐不躺”原则哦！

额头上贴“第三只眼”，让你能边走路边看手机

An industrial design student Minwook Paenghas created a high-tech third eye that can be affixedto a person’s forehead and look out for obstacles asthey walk， while their real eyes are glued to theirsmartphone. Paeng’s Third eye consists of a translucentplastic case that is fixed directly to the wearer’sforehead with a thin gel pad. Inside this plastic eyeare a small speaker， a gyroscopic sensor and a sonarsensor. When the gyroscope detects when the user’shead is angled down， it opens the eye’s plastic eyelidand the sonar starts to monitor the area in front of theuser. When it detects an obstacle， it warns the wearervia the connected speaker. Paeng said his Third Eyeis the first project that tries to imagine what the futuregenerations of “phono sapiens”may end up looking like.

走路玩手機，很危险，如果能像二郎神一样拥有第三只眼睛就好了。工业设计专业的学生彭敏旭，就发明了一款高科技产品——“第三只眼”。从表面看，“第三只眼”是一个半透明的塑料盒，用薄胶垫就能贴在额头上。这只“眼睛”内置有小扬声器、回转传感器和声波定位传感器。当你低头看手机时，回转传感器会检测到，从而开启塑料眼皮，声波定位仪接着就会监测前方区域;当传感器检测到障碍物时，将通过连接的扬声器发出警告。“第三只眼”正试着想象未来“手机人类”的面貌。
