Smartphones, poor sight

Look around and you’ll see people busy on their smartphones. Smartphones do make our lives easier . But have you ever thought about what they mean to your eyes?

According to a study, half of British people own smartphones and they spend an average (平均) of two hours a day using them. There has been a 35% increase in the number of people in the UK who suffer from shortsightedness(近视)since smartphones were introduced there in 1997.

Staring(盯)at smartphones for long time gives you dry eyes. When looking at something in the distance, your eyes automatically blink(自动眨眼)a certain number of times. However, when you look at things closer to your face, the blinking slows down. This reduces the amount of tears and causes discomfort in your eyes. Another bad habit is using smartphones in dark rooms before going to sleep. If you look at a bright screen while your pupils(瞳孔)become larger, too much light enters your eyes. This can do harm to the eyes and cause a disease called glaucoma(青光眼).

While you’re probably not going to stop using to your smart phone, there are a few things you can do to protect your eyes. Hold your phone at least 30 centimeters away from your eyes when using it. Take a break every hour and try the following: look at something at least five meters from you and then focus on the tip of your nose. Repeat this several times. It should reduce the discomfort in your eyes.

Answer the questions.

Only animals have the ability to see clearly when it is completely dark. A young boy who lives in a remote Chinese village seems to have the same ability.

Nong Youhui’s parents live in China’s Guangxi Province (省). They noticed their son’s eyes were different on the day he was born. Instead of black or dark brown, the common color for Asian babies, they were a light blue. Even more unusual was the fact that when a flashlight was shined upon them, they would give a bluish-green light just like the eyes of a cat.

However, when the parents went to see the village doctor, he told them that they would turn to black or dark brown, as he grew older.

Since the young boy was normal in every other way, the parents soon got used to his beautiful eyes and life went on as usual. Then a few days ago, Nong Youhui’s teacher heard him complaining about how difficult it was for him to see in the bright sunlight. When a classmate joked that his eyes looked like those of a cat, the teacher decided to do something. He shone a flashlight into young Nong’s eyes—They in turn, flashed back.

When he asked Nong if he could see in the dark, the young boy said yes. To test his words the teacher invited him to catch crickets(蟋蟀) on a dark night – Sure enough, the young boy needed no human produced light – His shining eyes were enough to catch the crickets.

The news, which came about in 2013, has changed Nong Youhui’s life forever. As news spread, experts from all over the world flew in to examine his special power.

Cat-boy, as he is noe called, has become world famous and recently, even earned himself a place in a new Guinness World Record (吉尼斯世界纪录)– The first human who can see in the dark! How cool is that?
