Playing computer games could help to prevent eye problems
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 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 may not sound all that ground-breaking, but contrast sensitivity is one of the most easily damaged functions of the 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 methodically to train the eyes to develop these skills, and that 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 it’s not all video games that could have this effect. The study compared different types of computer games by testing young adults who did not normally play games both before and after a period of playing them regularly. The results revealed that subjects who played first-person shooter or action games such as 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, which means 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 eyesight, it’s still not advisable to be sitting in front of a screen for long periods of time, or to allow gaming to replace other activities necessary to staying fit and healthy. In theory it’s certainly a nice idea, but it’s important to remember that it’s just as possible that video games could well be harmful in other ways.
Do I need a special prescription to get computer glasses?
I have a regular prescription for glasses which I haven't gotten made yet. It's actually a few months old, I just didn't have the money to invest and was using my old glasses. Now, with my old glasses I am having to strain when i look at the computer. I'm pretty ignorant when it comes to computer glasses. Do I need a different prescription to get computer glasses or can I use the prescription I have and tell Lenscrafters to make them computer glasses?
Yes, you need the proper prescription - Lenscrafters is not allowed to fudge around with the doctor's prescriptions. I am looking at the screen through mono-focal computer glasses as I have for years. When I go to get prescription updates, I specify how far I want the glasses to focus - just beyond arms length for my computer glasses because that is where I put the screen when sitting back at the keyboard.
I also get driving glasses - far distance prescription, because my trifocals are set up for indoor use and talking to people.
Also, you need to know that if you get trifocals that the center is not set by prescription - it is just between the upper and lower parts and thus may only be approximate for the computer screen.
I have had bifocals with the upper for computer use and the lower for reading papers when I had to do a lot of transferring of data. When teaching about using computers, I have also recommended to people who really needed them either over and under or right/left bifocals where the lower part (or left part) was for the computer and the upper (or right) part was for talking to people as by a receptionist where they had to switch from a screen a couple of feet away to people on the other side of a desk 6-8 feet away and their eyes needed glasses to focus on either. Obviously with computer vision on the bottom, you have to lower the screen as far as possible and tilt the head back - with right/left you turn your head on your neck instead of tilting.
