Students had to quickly identify the orientation of the middle "T" - Action game players could do it better - Image courtesy University of Rochester
Research says playing video games improves your bottom line on a standard eye chart

Video games that contain high levels of action can actually improve your vision, claim researchers at the University of Rochester. Their findings, which will appear in the journal Psychological Science, show that people who played action video games for a few hours a day over the course of a month improved by about 20 percent in their ability to identify letters presented in clutter—a visual acuity test similar to ones used in regular ophthalmology clinics.

 “Action video game play changes the way our brains process visual information,” says Daphne Bavelier, professor of brain and cognitive sciences at the University of Rochester. “After just 30 hours, players showed a substantial increase in the spatial resolution of their vision, meaning they could see figures like those on an eye chart more clearly, even when other symbols crowded in.”

Bavelier and graduate student Shawn Green tested college students who had played few, if any, video games in the last year. “That alone was pretty tough,” says Green. “Nearly everybody on a campus plays video games.”

At the outset, the students were given a crowding test, which measured how well they could discern the orientation of a “T” within a crowd of other distracting symbols—a sort of electronic eye chart. Students were then divided into two groups. The experimental group played Unreal Tournament for roughly one hour a day. The control group played Tetris, a game the researchers believe is equally demanding in terms of motor control, but visually less complex than the shooter.

After about a month of near-daily gaming, the Tetris players showed no improvement on the test, but the Unreal Tournament players could tell which way the “T” was pointing much more easily than they had just a month earlier.

“When people play action games, they're changing the brain's pathway responsible for visual processing,” says Bavelier. “These games push the human visual system to the limits and the brain adapts to it. That learning carries over into other activities and possibly everyday life.”

The improvement was seen both in the part of the visual field where video game players typically play, but also beyond—the part of your vision beyond the monitor. The students' vision improved in the center and at the periphery where they had not been “trained.” That suggests that people with visual deficits, such as amblyopic patients, may also be able to gain an increase in their visual acuity with special rehabilitation software that reproduces an action game's need to identify objects very quickly.

Ah, but this one is only for an hour. I wonder if a follow up study would define a threshold (number of hours playing) for when your vision goes south, because it is known that staring at a computer screen for too long strains the eye.

Well, if you think about it, staring at a TV is probably a bit easier on the eyes. Fonts are typically (if not always) larger and the fact that you are significantly further away from a TV than you are from a Computer Screen. Maybe that doesn't all make a difference, but sitting infront of a computer screen is more taxing on the eyes me thinks.

Well you are half right. However it has little do with what you are doing on the computer, high action game, spreadsheets, writing emails -- your eye doesn't care about that. Its the length of time you spend at a computer w/o taking any kind of breaks. If you think I'm kidding or full of shit, re-state what I said here to a certified and respectable optometrist.

It is recommended that to avoid your ayes from drying out - you are "supposed" to take your eyes off the screen every 20-30 minutes and at that time you re-focus your eye on something...say even a dot on the wall or ceiling. Another suggestion, and this is all from literature at my doctor's office...you are supposed to also every 30 minutes or so take some deep breathes - the claim here is that it ozygeniates the blood and some how or another this is good for your eyes.

No matter how much you do or don't blink, provided you blink at all, bad vision is by far more caused genetic or physical injury than stress injury.

Action game players don't have better eyesight because they play this crap, action game players have better perception because their brain has to kicks ass instead of stay calm and focused.

That's my opinion and argument, anyway.

That, and many people do not configure their monitors to work in a good refresh rate.

CRT & projector style monitors only on this one.

I tend to be able to notice a flicker up to and below 97 Hz (test image at 320x240 on a magical monitor that survives quick granular out-of-spec resolution changing thru powerstrip), at the magical number of 97 Hz it looks like an entirely solid flickerless image to me... but 75 Hz is comfortable, and 85 Hz is effortless.

I think it varies between people, but anyone training their eyes on a CRT at 60Hz is going to piss their eyes off.

Demand 85 Hz (CRT) or alternate monitor technologies (LCD) or better.

Care to point to any actual scientific studies that show that? Hint: there aren't any.

Looking at a computer screen is no different from looking at a piece of paper or at the world around you. A (CRT) screen with low refresh rates can cause headaches and trigger some nervous problems, and a screen with poor focus can cause eye strain. Neither of these problems happens with good monitors and neither of them has any permanent effect on your eyes. Both are more likely to happen with TV sets than computer monitors, BTW.

With the exception of strong ultraviolet light (and a couple of other types of radiation, none of which are emitted by monitors), simply looking at things will never damage your eyes.

A high quality CRT is actually better for text reading than an LCD, since the LCD has the "screen-door" effect and can break up letters.

Also, LCDs are typically brighter than CRTs, which also is bad for your eyes.

If you have perfect vision now, savor it and don't go into a field where you'll be staring at a screen all day. I have perfect vision (20/20 and 20/15) but since I started my programming job my eyes are almost always tired and have difficulty focusing on nearby things in less than perfect light. I talked to my doctor and he said it's eye fatigue so it's nothing physically wrong with me, but I should take frequent breaks during the day and look at something far away instead of the screen.

I would think that if someone were required to go bird-watching for as often as these people played games, they would soon be able to identify more birds hidden in trees and such. Their vision doesn't necessarily improve, just their ability to do a certain visual task. But then, is that the essence of vision? Head asplode.

I agree with you on this. I don't think this study reflects vision at all with the study's example that dailytech provided. Understanding the orientation of a 'T'? Please, that's not correlating to my vision! What they're processing is the response time between seeing the image and remarking on the orientation.

Just because I've played games for a good portion of my life doesn't mean I don't need my glasses to see normally (astigmatism = normal contacts make using a PC unbearable).

Wrong, eyesight is a subset (part) of vision. Or else why would glasses be considered "vision correction" when all they do is adjust the angles at which light are refracted onto the sensory section in the back of the eye. I.e. all they do is affect your eye's ability to work properly.

To me, it still sounds like they're trying to bolster up the newsworthiness on this finding when I recall other studies finding the exact same thing (i.e. video games that require higher reaction time will improve the human's reaction time outside of the game).

I dont think the conclusion was correctly derived from the data. Their nearsight/farsight was probably affected negatively, but the study found the gamer-subject's ability to discern, not "see," improved.
They should have done a more thorough vision test.

I've been staring at computer screens for the past 30 years, usually for 8 hours a day or more. I have perfect vision. I know lots of people who need glasses, and they don't spend nearly as long using computers (or looking at screens, or papers, or anything else) as I do.

So, care to provide any scientific data to back up your claim? The people responsible for this study did just that, so how is your "theory" (pulled out of thin air, or at most based on one case - yours) more valid than theirs?

Basically what you're saying is that any scientific results that disagree with your opinion are wrong and whoever found them needs to be "smacked around the head". Hey, how's that for short-sightedness?

Unless your father has a twin brother who sees perfectly, and the only difference between them is the fact that your father "stared at computer screens" and his brother didn't, that "example" is absolutely meaningless. My uncle has terrible eyesight, and he's a farmer. Surely that proves that staring at lettuces screws up your eyesight, no?

It's sad that some people can't understand how science works, but it's even sadder when they conclude that, since they can't understand it, it must be wrong.

Someone was on the right track when he/she questioned the link between vision improvement and mental process.

If you read carefully, you will see that the ability to single out individual symbols "crowded" by other symbols improves-- i.e. the ability to more quickly resolve discrete visual symbols in close proximity, all of which are within the range of optical resolution.

If you (or these researchers) believe this has any bearing on the ability to improve optical focus on our own, you are mistaken. People vouch for things that are not true all the time. Aldous Huxley is probably the most famous adherent to the school of training eye muscles to improve vision.

None of that changes the fact that it is anatomically impossible:

Accomodation is the process by which the eye adjusts focal distance. Elementary anatomy will show you that this process (in humans) involves alteration of the shape of the lens. That is, the adjustment takes place within the eye. The notion that accomodation can be performed by changing the length of the eyeball itself, using muscles around the eye, is anatomically false. It is, however, true for fish.

No, you cannot improve your optical focus or resolution by any training process, including gaming. If you are wearing glasses, it is because there is an irregularity in the shape of your lens, and there is nothing you can do about it except redistribute the incoming light accordingly: glasses or contacts.

I understand there are a lot of people who are attached to Huxley's (rather, Dr. Bates') ideas, or to random chance ("I'm the only one in my family who doesn't wear glasses, and I do X every day"); that does not make the conclusions any less false. I'm not trying to start a flame war. But, folks, we can make eletron scans of large atoms to see their structure, and we can predict some quantum activities with accuracies upward of 8 decimal places. We're talking about basic anatomy here-- stuff you can verify with a few minutes of spare time with online human anatomy slides. Let it go.

While the test showed improvement in objectual awareness, the damaging effects should also be studied/analysed as I'm sure it doesnt help you if you're short/long sighted.

I think that games such as these also greatly enhance your sensitivity to sounds, movement, spatial awareness, etc. I would be interested to see if these type of games help hearing as much as eyesight! From my experience, this is definately a yes.
