Vocabulary: eyesight 詞匯: 視力
These days there is so much tempting technology to look at: smartphones, tablets, computer games and TV screens. Much of our entertainment and education comes from using them, so it's no wonder we spend so much time staring at them. But even if the saying that looking at a screen for too long gives you?square eyes?isn't true, there is still some concern that it can affect your eyesight. So, should we be worried?
Certainly for children who spend hours?glued to?a screen there is a concern that their health might be at risk. The lack of physical activity can lead to an increase in their weight. But there is a fear that their eyesight is?deteriorating?too. Although there's not much evidence to prove this yet, recent findings have?opened our eyes?to the issue.
Katherine Sellgren from BBC News spoke to Chris Hammond, professor of?ophthalmologyat King's College London and consultant?ophthalmic?surgeon at St Thomas' Hospital. He said "We know that?myopia, or?short-sightedness, is becoming more common… It has reached?epidemiclevels in East Asia, Singapore, Taiwan, South Korea, where approaching 90% of 18-year-olds are now?short-sighted."
But can this be linked to children's obsession with using electronic gadgets? Annegret Dahlmann-Noor, consultant?ophthalmologist?at Moorfields Eye Hospital in London says lack of?natural lightseems to be the key issue. She's suggested that children in East Asia study a lot, using computers, smartphones or tablets, and they are go outside less, which could be a cause of short-sightedness. Wearing?glasses?is one solution, but it's not ideal.
This leads to a dilemma: achieving short-term academic success or protecting your long-term eyesight. It's always going to be a challenge to drag children away from their screens and it's likely that more and more studying will be done online, through a screen. But despite that, Professor Hammond says, "in countries like urban China, where 10% of children in each class per year are becoming short-sighted from about the age of six, there's an argument for saying we should be trying to prevent it." It's evidence we can't?turn a blind eye?to. So, maybe it's time to hit the 'off' button and get our children outside?
