Myopia is increasingly affecting young people in Taiwan, with close to 90 percent of children in Taiwan’s major cities suffering from nearsightedness. If myopia is not controlled and a child’s vision worsens, their eyesight could be damaged, even with treatment. In these cases, it could cause complications such as degeneration, detachment or tearing of the retina, macular degeneration, cataracts and glaucoma. In serious cases surgery may be required, and the complications could even lead to impaired vision.
Main preventative treatments for myopia are the application of Atropine drops or wearing corneal reshaping lenses. The more concentrated the Atropine drops are, the more effective they are at controlling the myopia, but the stronger the side effects, including photophobia, blurred vision, will be and, if used incorrectly, they could even drastically exacerbate the myopia.
Corneal reshaping lenses are contact lenses to be worn overnight, and must be worn for at least eight hours while sleeping. The biggest problem and greatest risk with these contacts, just as with conventional contact lenses, is infection. If they are not cleaned properly they could breed pathogenic bacteria, leading to corneal infection.

台灣近視年輕化，台灣都市近九成小朋友近視。小朋友近視若未能控制而惡化，即使治療，視力仍可能受損，將會引發視網膜變性、視網膜剝離、視網膜裂孔、黃斑部退化、白內障、青光眼等併發症。嚴重者需要開刀治療，甚至可能導致失明。
預防近視，點散瞳劑及配戴角膜塑型片是主要方法。其中散瞳劑的濃度愈高，抑制近視效果愈強，副作用也愈強，包括畏光、視力模糊，但若不規則使用，反而會使近視度數急速增加。
角膜塑型片是夜戴型隱形眼鏡，需要在睡覺時使用至少八小時。塑型片最大缺點和風險是感染，如同一般隱形眼鏡，塑型片若清洗不乾淨，可能會沾黏孳生病源菌，導致角膜感染。

Chinese automobile manufacturer Zotye Auto is a household name in China. The company is famous for manufacturing copies of car models by luxury international brands including Audi, Porsche and Lamborghini. After a long delay, on June 22, Zotye Auto finally released its 2019 year end financial results. The report revealed that last year, the automaker suffered losses of 11.2 billion yuan (approximately NT$46.6 billion), or an average of 30 million yuan per day. The company’s market value also shrank from 30 billion yuan to a mere 3.6 billion yuan. Even worse, because the company is unable to guarantee the authenticity,
Onions, with their sweet aroma, are a popular cooking ingredient, used in both Western and Eastern cuisines. Today, however, information is appearing online suggesting that onions should not be eaten with fish, shrimp, seaweed or honey, as these combinations cause kidney stones. But is there any truth to this? The Taiwan FactCheck Center asked dieticians and experts and confirmed that this information was false. Onion loving foodies everywhere can breathe a sigh of relief. According to information on certain social media platforms, onions should not be eaten together with fish, as the fish has a high protein content, and the oxalic
Pluto, a frigid little world inhabiting the solar system’s outer reaches, may have been born as a warmer place sheltering a subsurface ocean that still exists today, researchers said on Monday. An analysis of images of its surface taken in 2015 by NASA’s New Horizons spacecraft and computer simulations of the dwarf planet’s interior led the researchers to propose a “hot start” scenario for Pluto’s formation some 4.5 billion years ago as the solar system, including Earth, took shape. “When Pluto was forming, new material would have been coming in and impacting its surface. Each impact is like an explosion that
Segway Inc. announced last week that it will end production of its iconic two-wheeled personal vehicle starting July 15. When the company launched the product nearly two decades ago, it boldly claimed that its namesake two-wheeler would revolutionize the way people move, but it only sold 140,000 units across the world. The Segway was criticized for the high price tag of US$4,950 (about NT$147,000). It was also challenging to ride, because riders must maintain a balance at a specific angle for the vehicle to move forward, and can easily be thrown off if they lose control. Several months after buying the
