Yet another study on nearsightedness says more of us will develop the condition.
然而，有關近視的另一項研究表明，更多的人可能會患有近視。
Other studies have shown there's an increase in nearsightedness in different regions of the world, but this study analyzed data on nearsightedness from around the globe.
其它研究已經表明，世界不同地區的近視數在增加，但該研究分析了來自世界各地的近視數據。
The study in the journal Ophthalmology looked at 145 studies encompassing 2.1 million people. Based on the analysis, researchers say about half the world will be nearsighted by 2050.
眼科學雜志進行了145項研究，涉及210萬人。基于分析，研究人員稱到2050年大約有一半的人口會患有近視。
And about 10 percent will have high myopia, or nearsightedness, based on researchers' estimates.
根據研究人員的估計，約百分之十將有高度近視。
Those numbers could be pretty serious, considering nearsightedness could put you at an increased risk for permanent vision loss.
考慮到近視會讓你增加永久性視力喪失的風險，這些數字可能是相當嚴重的。
A growing body of research on the condition suggests more time indoors, increased screen time and high-pressure education systems are partially to blame.
越來越多的研究表明，待在室內時間越長、面對屏幕的時間越長以及高壓力的教育體系是造成近視的部分原因。
The study in Ophthalmology suggests if urbanization continues increasing across the world, that 2050 estimate could be difficult to avoid.
眼科學研究表明，如果世界各地城鎮化繼續增加，2050的估計可能是難以避免的。
Some research suggests lifestyle changes like spending more time outside and taking frequent breaks from the computer screen might reduce your risk of nearsightedness.
一些研究表明，改變生活方式，像花更多的時間在戶外、面對電腦屏幕經常休息可能會降低你患近視的風險。
