Grapes Are Good for our Eyesight葡萄對我們的視力有益

Everybody knows that eating carrots is good for our eyesight. A new studysuggests that grapes are also good for our eyes. Researchers from the NationalUniversity of Singapore have found that eating just a few grapes a day can help oureyesight. This is good for people who are older.

Dr. Eun Kim， the lead2 researcher， said， “Our study is the first to show thatgrape consumption3 is good for eye health of humans， which is very exciting，especially4 with more people who are getting old.”

She said that grapes are easy to buy and studies have shown they can do muchgood to our eyesight. This is good news for people who don’t really like carrots.

Thirty-four people took part in a number of tests over 16 weeks in the study.Half of them ate one-and-a-half cups of grapes every day; the other half ate asnack5. Dr. Kim did not tell anyone whether she was testing the grapes or thesnack. She thought that it would give better test results.

She found that people who ate the grapes had improved muscle strength6around the retina7. The retina passes information about light to the brain byelectrical signals8. It protects9 the eyes from bluelight which is bad for our eyes. A lot of blue lightcomes from computer and smartphone screens10， andfrom LED lights.

每個人都知道吃胡蘿卜對我們的視力有好處。一項新的研究表明，葡萄對我們的眼睛也有好處。新加坡國立大學的研究人員發(fā)現(xiàn)，每天只吃幾顆葡萄就可以幫助改善我們的視力。這對老年人也有好處。

首席研究員金恩博士說：“我們的研究首次表明食用葡萄有利于人類的眼睛健康，這令人非常興奮，尤其是對越來越多的老年人來說。”

她說葡萄很容易買到，并且研究表明它們對我們的視力有很大好處。這對那些不喜歡吃胡蘿卜的人來說是個好消息。

該研究有34 人參加了為期16 周的多項測試。其中一半的人每天吃一杯半的葡萄；另一半吃零食。金博士沒有告訴任何人她是在測試葡萄還是零食。她認為這會得出更好的測試結(jié)果。

她發(fā)現(xiàn)吃葡萄的人視網(wǎng)膜周圍的肌肉力量得到了改善。視網(wǎng)膜通過電信號將光的信息傳遞給大腦。它保護眼睛免受藍光的傷害。許多藍光來自電腦和智能手機屏幕，以及LED 燈。
