研究顯示 長時間待在教室會導致近視
The more years you spend in full-time education, the more short-sighted you are likely to be, according to a large UK study.
英國一項大型研究顯示，你接受的全日制教育的時間越長，你的近視程度就可能越高。The link appears to be that students have too little exposure to bright natural light -- and the antidote suggested by the researchers is for children to spend more of the day outdoors.
原因似乎是由於學生們接觸到的明亮自然光太少，研究人員建議的解決辦法是讓孩子們白天在戶外多待一段時間。The study, carried out by Cardiff and Bristol university scientists, analysed information on the genetics, eyesight and educational background of 68,000 participants in the UK Biobank database.
這項由英國卡迪夫大學和布里斯托大學的科學家們開展的研究，對英國生物樣本庫中6.8萬名參與者的基因、視力和教育背景信息進行了分析。
The findings, published in the BMJ, imply that a graduate who spent 17 years in education is on average one dioptre more short-sighted that someone who left school at the age of 16 after spending 12 years in education.
發表在《英國醫學雜誌》上的這篇研究報告顯示，平均來說，一名受過17年教育的畢業生，比一名受過12年教育、16歲就輟學的學生的近視程度要高100度。
That deterioration is equivalent to the difference between having perfect vision and needing glasses to drive safely.
這種視力退化相當於擁有完美視力和需要戴眼鏡才能安全駕駛之間的區別。"With the rapid rise in the global prevalence of myopia and its vision-threatening complications, together with the economic burden of visual loss, the findings of this study have important implications for educational practices," said Jez Guggenheim, of Cardiff University's School of Optometry and Vision Sciences.
卡迪夫大學視光學和視覺科學學院的傑斯·古根海姆稱：“由於近視及威脅視力的併發症的全球發病率的快速增加，以及視力損失的經濟負擔，這項研究成果對教育實踐有着重要的意義。”Using Biobank data, the Bristol and Cardiff scientists analysed 44 genetic variants associated with risk of myopia and 69 variants associated with time spent in education.
使用英國生物樣本庫的數據，布里斯托大學和卡迪夫大學的科學家分析了44種與近視風險相關的基因變異、以及69種與受教育時間相關的變異。They found that while the number of years at school and college strongly influenced eyesight, there was no effect in the opposite direction: propensity to myopia did not lead people to remain in education for longer.
他們發現，雖然在中小學和大學學習的時間對視力有很大的影響，但反過來卻不成立：即近視傾向不會導致人們接受教育的時間延長。
