Smartphone, 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 of two hours a day using them. There has been a 35% increasing in the number of people in the UK who suffer from shortsightedness since smartphones were introduced there in 1997.

Starting at smartphones for long time gives you dry eyes. When looking at something in the distance, your eyes automatically blink 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 room 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 hard to the eyes and cause a disease called glaucoma .

While you’re probably not going to stop using your smartphones, 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 away from you and then focus on the tip of your nose. Repeat this several times, it should reduce the discomfort in your eyes.
