An eye specialist is warning parents and students about the misuse of laser pens, which can be purchased easily but have harmed the eyesight of a number of children in recent months.Laser pens are often used as pointers by teachers in classrooms, and have become popular with some schoolchildren in Chengdu, Sichuan province.Sold in many stationery shops in the city, most are priced between 5 yuan and 200 yuan ($0.8-$31). They can emit a narrow beam of light in either red, blue or green with a single click of a button.But pointing a laser beam into a person's eyes can damage the delicate organs. A number of students have sought treatment at the Ineye Hospital of Chengdu University of Traditional Chinese Medicine.Xie Airui, an eye specialist at the hospital, has received two boys since September whose visual acuity fell off sharply after incidents involving laser pens. The first boy's eyes were burned. He couldn't see an object 10 centimeters away. A checkup showed that the macular area of his retina had been damaged, Xie said.The macular area is the most sensitive part of the eye and critical for vision, she said.The second boy, a high school student, was 15 when he sought treatment from Xie in September, after a classmate pointed a laser pen at him.A test found that the macular areas of both his eyes were burned and had obvious scarring. He could only see objects within 50 centimeters, Xie said.The resulting scars were consistent with those left by clinical lasers, she said, noting that damage to the macular areas can be permanent.Four years ago, the General Administration of Quality Supervision, Inspection and Quarantine issued a warning that laser pens could harm consumers. But no market supervisors have taken up the matter in a serious way, according to Xu Bin, a lawyer in Chengdu. 202mm to inchescustomise fidget spinner24hourwristbandsballer bandsflash drive wristbandplastic wristbands ukbatman wristbandbracelet maker onlineblack rubber bracelets
Bill Gates speaks at Peking University in Beijing, on March 24, 2017. [Photo by Zhu Xingxin/chinadaily.com.cn] China is committed, ambitious and vital, according to Microsoft founder Bill Gates. The billionaire philanthropist was among leading business figures, academics and opinion leaders from around the world who were asked by China Daily to sum up China in just three words. Apart from the somewhat obvious big, words which regularly came up from respondents were innovative, dynamic and transforming, reflecting some of the spirit of the Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era outlined in the general secretary's report to the 19th CPC National Congress. Gates said he wanted his selection of words to reflect the fact that China was now very important to the future of the entire world. Committed, because as much as any other country over the past few years, China has shown a commitment to health and development both at home and abroad. Ambitious, because of the targets it has set for itself, including wiping out extreme poverty by 2020. And vital, because we need an engaged and responsible China if we are to rid the world of what we call 'solvable human misery', he responded.
