Smartphone, poor sight

Look around and you will see people busy on their smatrphones (智能手机). Smartphones do make our lives easier. But have you ever thought about what they mean to your eyes?

According to a study, half of the 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 U.K who suffer from short-sightedness (近视) since smartphones were introduced there in 1997.

Staring (盯)at smartphones for a 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 the things closer to your face, the blink slows down. This reduces the amount of tears and causes discomfort in your eyes. Another bad habit is using smartphone in dark rooms before going to sleep. If you look at a bright screen while your pupils (瞳孔) become larger, too much light goes into your eyes. This can be bad for your eyes and causes a disease called glaucoma (青光眼).

Maybe it is possible for you to stop using your smartphone, but 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 5 meters away from you and then focus on your nose. Repeat this several times. It should reduce the discomfort in your eyes.
