The Health Promotion Administration urged parents to limit children’s usage of electronic devices, because of potential damage to the eyes.
Studies show that when people spend long periods looking at an electronic device at close range, the blue light emitted by the LED screen stimulates the production of free radicals and causes damage to the retinal cells, the agency said.
Parents should limit screen time for children over the age of two to one hour per day, while children who are less than two years old should avoid looking at electronic devices altogether, it said.
The agency also recommended a 10-minute break for every 30 minutes of usage.
The younger the person is when they develop nearsightedness, the quicker their vision worsens, the agency said.
If it is not kept under control, it could easily develop into acute myopia, which in turn could lead to early onset of cataracts, glaucoma, retinal detachment or macular degeneration, it said.
Prolonged use of electronic devices by adults also makes them to susceptible to worsening vision, early onset of cataracts and retinopathy, it added.
To prevent poor vision, people should engage in outdoor activities for at least two to three hours a day. When using electronic devices they should have proper lightining, maintain good posture and keep 35cm to 45cm away from the screen, the agency said.
People should also get regular eye exams once or twice a year, the agency added.
Tropical depression TD22, which was over waters south of the Ryukyu Islands, is likely to develop into a tropical storm by this morning and pose a significant threat to Taiwan next week, the Central Weather Administration (CWA) said yesterday. The depression is likely to strengthen into a tropical storm named Krathon as it moves south and then veers north toward waters off Taiwan’s eastern coast, CWA forecaster Hsu Chung-yi (徐仲毅) said. Given the favorable environmental conditions for its development, TD22’s intensity would reach at least typhoon levels, Hsu said. As of 2pm yesterday, the tropical depression was about 610km east-southeast of Taiwan proper’s
Four factors led to the declaration of a typhoon day and the cancelation of classes yesterday, Taipei Mayor Chiang Wan-an (蔣萬安) said. Work and classes were canceled across Taiwan yesterday as Typhoon Krathon was forecast to make landfall in the southern part of the country. However, northern Taiwan had only heavy winds during the day and rain in the evening, leading some to criticize the cancelation. Speaking at a Taipei City Council meeting yesterday, Chiang said the decision was made due to the possibility of landslides and other problems in mountainous areas, the need to avoid a potentially dangerous commute for those

SEMICONDUCTORS: TSMC is able to produce 2-nanometer chips and mass production is expected to be launched by next year, the company said In leading-edge semiconductor manufacturing China is behind Taiwan Semiconductor Manufacturing Co (TSMC) by at least 10 years as the Taiwanese chipmaker’s manufacturing process has progressed to 2 nanometers, National Science and Technology Council (NSTC) Minister Wu Cheng-wen (吳誠文) said yesterday. Wu made the remarks during a meeting of the Legislative Yuan’s Education and Culture Committee when asked by Democratic Progressive Party Legislator Wu Pei-yi (吳沛憶) about a report published in August by the Chinese version of Nikkei Asia that said Taiwan’s lead over China in chip manufacturing was only three years. She asked Wu Cheng-wen if the report was an accurate
