These days there is so much tempting technology to look at: smartphones, tablets, computer games and TV screens. Much of our children’s entertainment and education comes from using them, so it’s no wonder that children spend so much time staring at them. But even if the saying that looking at a screen for too long gives them square eyes isn’t true, there is still some concern that it can affect their 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, and their eyesight is worsening too. Although there’s not much evidence to prove this yet, recent findings have opened our eyes to the issue.

Chris Hammond, consultant ophthalmic（眼科的）surgeon at St Thomas’ Hospital, says, “We know that short-sightedness is becoming more common. It has spread greatly in East Asia, Singapore, South Korea, where about 90% of 18-year-olds are now short-sighted.” Annegret, expert at Moorfields Eye Hospital in London says lack of natural light seems to be the key issue. She’s suggested that children in East Asia study a lot, using computers, smartphones or tablets, and they go outside less, which could be a cause of short-sightedness and an increase in their weight. Wearing glasses is one solution, but it’s not ideal（理想的）.

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.
