Excessive Screen Time Could Affect Eyesight

Nov 12th 2013, 07:37

Modern technology has brought out a new concept called ‘screen time,’ which is the time that we spend in front of a screen. The size of the screen varies widely, from the size of a wristwatch to that of a large television screen. Books are being replaced by eBook readers and tablets; files at workplace are replaced by computers and laptops. And if we have some time to while away, we often find ourselves exploring our smartphones.
There is no denying that technology has made our life easier, but anything excessive could have its problems. A recent survey commissioned by Spectrum Thea eye care specialists in Britain has provided some eye-opening statistics. According to the survey which covered 2000 individuals between the ages of 16 and 24 years, an average Briton spends 11 hours a day looking at a screen. This number appears frightening, since it is almost half a day.

How could excessive screen time affect a person? The main effect is on the eyes. While people stare at the screen with full concentration, they forget to blink regularly. Blinking causes the eyes to be coated with a thin film of tear, thus keeping it moist. Excessive screen time results in evaporation of the tear film and could therefore result in dry eyes. In fact, the survey found that more than half the individuals suffered from problems related to dry eyes. The eyes may also become inflamed. There is a possibility that smartphones could result in short sightedness.

Another problem posed by the screens is their interference with family life. The British survey found that people spend only around 13 hours of quality time with their family each week and slightly less than six hours walking outside. Thus, screens have intruded into the personal lives of individuals and may also affect their fitness and health. Sitting in front of the computer or TV screen can increase the chances of back problems and predispose to obesity.

Younger people are likely to spend more time in front of screens during their lifetime, and are therefore at a higher risk of suffering from eye-related and other problems. It is important to point out that a regular eye check would be necessary to detect eye problems early and prevent any long-term complications. Regulation of total screen time in children is a necessity, while self regulation is important in adults.
