Babies born in summer are more likely to become short-sighted in late life, a study has shown.
As many as a quarter of all cases of short-sightedness are caused by too great an exposure to sunlight in the first weeks of life, say eye experts.
They are advising all parents to put sunglasses on their babies during the first weeks.
Scientists had already established that over-exposure to sunlight caused shortsightedness in animals.
Researchers who compared the months in which babies were born with whether they needed glasses later on say the principle also applies to humans.
A study of almost 300, 000 young adults-the largest of its kind-showed that those born in June and July had a 25 per cent greater chance of becoming severely short-sighted than those born in December or January.
Research leader Professor Michael Belkin, of Tel Aviv University, said it was because prolonged illumination(光照) causes the eyeball to lengthen-causing short-sightedness.
Hence the more light a newborn is exposed to, the more the eyeball lengthens and the worse the short-sightedness will be.
The mechanism which lengthens the eyeball is associated with levels of melatonin(褪黑激素), a pigment (色素) which protects the skin against harmful rays of the sun.
In young babies not enough melatonin is released as protection, meaning they are more vulnerable to sunburn and changes to eyeball shape.
Sight expert Professor Daniel O'Leary, of Anglia Ruskin University in Cambridge, said "At the moment we don't know the precise cause of why light exposure affects sight, but the evidence seems to prove that it is one of the reasons for people becoming shortsighted."

We all see and hear about extraordinary people around us and wonder why we can't be more like them. It's not the big things that make someone extraordinary. Here are some small things that extraordinary people do every day:
●{#blank#}1{#/blank#}That you're the boss doesn't mean you are right every time. Learn to back up your decisions with reason. Use logic(逻辑) to explain things, not authority. By doing this your decisions might invite criticism, but you will also get an opportunity to improve.
●They are generous with compliments（恭维）. Remember the time, when you worked really hard but got nothing in return? Not even a thank- you. {#blank#}2{#/blank#} So every chance you get to praise someone, do it. A simple, “That was some great work, keep it up,” can go a long way in making the employees feel great about themselves. {#blank#}3{#/blank#}
●They are helpful. Never hesitate to help someone. It's fairly simple but it goes a long way. Don't say something vague（含糊）like, “Can I help you?” because they might just say, “No, I'm good.” {#blank#}4{#/blank#} “I had the same problem with this coffee machine in the morning. I think I have figured a way to make it work.” Offer in a way that feels mutually beneficial .
●They're in charge of their emotions. Sometimes it is very important to stay silent. Especially when you're angry, you don't want to end up saying things you didn't really mean to. So they take their time to think about what happened, and then come to a decision about how to deal with it. {#blank#}5{#/blank#} Never be too casual with words or actions.
A. They are sensitive to others. B. The key is to be specific. C. A compliment can have a positive impact on their lives. D. When you feel awkward receiving a compliment, give the person a smile. E. They are open to criticism. F. It hurts when your efforts are not recognized. G. Before you say anything, consider others' feelings. |
