Playing computer games could help to improve eyesight
After years of being told that video games are bad for your health and especially your eyes, a new study has proved that in fact playing some games may actually help improve your vision, and could even prevent you from needing glasses in the future. The study, conducted by the University of Rochester, demonstrates that regularly playing certain games improves a person’s contrast sensitivity function, or their ability to distinguish easily between different shades of grey. But does that really mean your eyesight has improved?
Shades of grey might not sound all that ground-breaking, but contrast sensitivity is one of the most commonly and easily damaged functions of the human eye. People who suffer from low contrast sensitivity find it harder to see at night or to pick out small details like spots on clothing, and often the only way to treat the problem is with increasing strength prescription glasses or eye surgery. It’s now believed that computer games could be used to train the eyes to develop these skills, and that it’s possible the same method could even be used to treat people who suffer from Amblyopia or ‘lazy eye’, a condition that affects the brain’s ability to correctly register signals from one eye.
But not all video games are thought to have this effect. The study compared two different types of games by testing young adults who did not normally play games both before and after a period of playing them regularly. The results suggested that subjects who played first-person shooter or action games like Call of Duty showed a 43 per cent improvement on average, whereas those who played non-action games such as The Sims 2 showed hardly any.
So if gaming could help us avoid eye problems should we all be rushing out to buy an XBOX with as many action games as we can find to ensure that our designer sunglasses will remain our only visual aids far into our future? Well, no. For a start the study makes a point that not all action games will work, in other words, most of them probably won’t. Not to mention the fact that although these games may help develop some areas of your sight, it’s still not advisable to be sitting in front of a screen for long periods of time, or to allow computer games to replace other activities necessary to staying fit and healthy. In theory it’s a nice idea, but it’s important not to forget that it’s just as possible that video games could well be harmful in other ways.
