Smartphone, 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 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 shortsightedness since smart phones were introduced there in 1997.

Staring at smart phones for a 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 smart phones in dark rooms before going to sleep. If you look at a bright screen while your pupils become larger, too much light enters your eyes. This can do harm to the eyes and cause a disease called glaucoma.

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 continues 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.
