A study found most people use their smart phones for an hour and 52 minutes a day. Most of this time is taken up with texting, emails and surfing the web, but only around 20 minutes is spent making three calls.

The survey of 2,000 people found that social media apps, calculators (计算器), calendars and cameras were

also seen as particularly important functions. Navigation apps (导航应用) such as Google Maps were popular too – with one in six people admitting they would feel unable to travel around an unfamiliar city without one. The study also found checking Facebook and taking pictures of others are carried out more frequently than making calls. Also on the list were the calendar to remember appointments and birthdays, mobile banking and the news are apps that make day-to-day life a little easier.

Tom Barr said: ‘The functions on a mobile phone have developed and improved drastically (剧烈) over the past 10 years. With so many ways to keep in touch nowadays, people are using the functions that are convenient for them. As we get less and less time to ourselves, we need more convenience in our lives and less difficulty. While calling can be more personal, it doesn’t always save your time.’

Scientists at Rice University wanted to see if the latest mobile technology would be used by the students to

improve their learning. But a year later, the researchers concluded that it’s not enough to give students the right

technology, but said they need guidance about how to use it.

Smart Phone, Poor Sight

Look around and you’ll see people busy on their smart phones. Smart phones 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 smart phones now and they spend an average of two hours a day using them. There has been a 35% increase in the number of people in the UK who suffer from short-sightedness since smart phones were introduced there in 1997.

Staring (盯) at smart phones screen 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 smart phones 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 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.
