Kids and Computer Screens
Cutting and pasting an animal scene, with child, on the Stanley
website today got me wondering about a few things regarding my child and my LCD monitor... 1. Does that "don't sit too close to the screen" warning about televisions also apply to LCD monitors? Was it even accurate with regards to TV? She likes to point things out on the screen, and now that I think about it, *everyone* sits pretty close to the computer screen, esp. compared to how we all watch TV. 2. Are LCD monitors damaged by touching with fingers? I don't mean sharp or jagged jabs. However, even the lightest touch causes a "ripple" of sorts in the screen. Are those light touches damaging? 3. And, how do you clean those screens safely? I assume that I can no longer use Windex, as I did on my old CRT. What works, also without damage? Thanks. P. Tierney |

Hi there, I've had LCD screens since they first started to get big Touching the sceen wont damage it, especially your childs fingers, LCD has two fluros (sp?) in it, which if break, your replace a fluro lights, one at the top, one on the right side i believe. I also think that sitting too close is a bit different to tvs, as we can spend a few hours watching tv... also on that though if your like me and work on computers your looking at it quite a bit, i believe they are made differently... but i would get up for a little walk about every 30 min - hour As for cleaning, i've always used windex, and its never damaged... but dont take my word on it as i could just be lucky! It should say it in your monitor intructions! HTH Leanne |

She likes to point things out on the screen, and now that I think about it, *everyone* sits pretty close to the computer screen, esp. compared to how we all watch TV. http://www.straightdope.com/classics/a5_105.html First the good news: according to most eye specialists, claims that you'll ruin your eyes by sitting too close to the TV, reading in bed, using inadequate light, etc., are old wives' tales. The bad news is that the old wives may have been right. First let's dispose of the TV threat. Virtually no one believes that under ordinary circumstances television watching poses any special danger. (Well, physically, anyway.) Prior to 1968 or so some sets emitted excessive X-rays, but that problem has now been eliminated. More recently concern has arisen about computer video display terminals (VDTs), which typically are viewed at much closer range than televisions; research is nconclusive so far but continuing. To be on the safe side some eye doctors say you shouldn't let your kids get closer than five feet to the TV screen, the room shouldn't be pitch black, etc. But the intention is to prevent eye fatigue, not eye damage. The more general (and more interesting) question you raise is this: is it possible to ruin your eyesight through overuse, close work, inadequate light, and so on? The usual answer from the MDs is no. But don't be too sure. A fair number of people believe that some eye problems, notably myopia (nearsightedness), are a "product of civilization," as one researcher puts it. The most striking demonstration of this was a study in the late 60s of eyesight among Eskimoes in Barrow, Alaska. These people had been introduced to the joys of civilization around World War II. The incidence of myopia in those age 56 and up was zero percent; in parents age 30 and up, 8 percent; in their children, 59 percent. The same phenomenon has turned up in studies of other newly-civilized peoples, suggesting that modern life somehow causes nearsightedness. But how? Nobody knows. The shift among the Eskimoes appeared to be too sudden to be explained by genetics alone (although there is little question that a predisposition to nearsightedness is inherited). On the theory that too much close focusing while young permanently distorts the eyeball, some experts gave kids regular doses of atropine, which relaxes the eye muscles. (Eye doctors use it to dilate your pupils prior to an exam.) A few claimed this halted myopia but failed to convince many of their peers, and there was the obvious practical problem that with your eyes dilated you couldn't see for beans. Other researchers blame dietary deficiences, e.g., not enough copper or chromium; excessive exposure to pesticides; and so on. But nothing has been proven. Animal studies tend to support the idea that myopia is caused by eyestrain. Normal monkeys are not myopic; neither are monkeys whose eyes are kept completely sealed off from light. But monkeys whose eyes were sutured so they could see only dimly (I realize this is the kind of thing that outrages animal rights activists) did become myopic, presumably because they could see something and strained their eyes trying to see more. The idea that the civilization means bad eyes is by no means universally accepted. The Alaska Eskimo study, for example, was criticized for not testing a random sample--presumably the main reason kids were brought to the Barrow clinic was that their parents thought they had vision problems, which of course skewed the results. Other studies have failed to find a correlation between environment and vision. So what's a father to do? Search me, pard. If you buy the eyestrain argument you could feed the kids whale blubber and chuck the books, TV, and needlepoint lessons, but the tradeoff might not be worth it. Having to wear eyeglasses is hardly a major handicap these days whereas being an uneducated mope is. Till such time as the myopia-inducing component of civilization (if any) is isolated, you're probably best off chalking up a little nearsightedness as a small price to pay for indoor plumbing. --CECIL ADAMS Btw, according to this, LCDs are less likely to cause eyestrain than CRTs http://www.staples.com/content/Article/I-N/LCDFAQs.asp LCD monitors Is it true that LCD monitors are easier on your eyes? Yes. Unlike CRT monitors, the images on LCD monitors refresh a pixel, rather than an entire line, at a time. The images on CRT monitors (as well as televisions) are redrawn at a rapid rate not usually discernable to the eye. This is why photographs of television and CRT screens don't turn out (and why when you look into a dark room brightened only by a television there seems to be mild strobe effect on the walls of the room). This refreshing of CRT screens (measured as frequency) can cause eyestrain for some people. LCDs do not flicker and often cause less eyestrain. 2. Are LCD monitors damaged by touching with fingers? I don't mean sharp or jagged jabs. However, even the lightest touch causes a "ripple" of sorts in the screen. Are those light touches damaging? http://www.tridentdisplays.co.uk/hom...s/pnews055.htm when you press on the front of an LCD monitor you leave finger marks that are very difficult to clean off. Worse still, an LCD can be very easily damaged by pressure, either from fingers or from sharper objects, like pens. 3. And, how do you clean those screens safely? I assume that I can no longer use Windex, as I did on my old CRT. What works, also without damage? I don't know about using windex but there are plenty of specialized cleaners on the market. They seem to come in premoistened pads. Rule No. 1 for safe cleaning is to follow the lcd monitor manufacturer's recommendations. If you've lost the computer's documentation, go to the manufacturer's Web site on the Internet and search for directions with terms like "clean monitor." Thanks. P.

(Eye doctors use it to dilate your pupils prior to an exam.) A few claimed this halted myopia but failed to convince many of their peers, and there was the obvious practical problem that with your eyes dilated you couldn't see for beans. In my family, all of us first four kids needed glasses quite young, and have REALLY bad nearsightedness. When our much younger siblings came along, there was a doctor using the atropine treatment, and my mom got them into the program: they used atropine regularly, had to wear sunglasses outdoors, and used reading glasses. (The dilation made the sunglasses necessary; the relaxed eye muscles meant they couldn't focus close, but reading glasses took care of that.) They were supposed to use the drops until they stopped growing. Unfortunately, the doctor died, and the one who took over his practice refused to continue the treatment, saying there was no proof that it worked. (It is not possible, after all, to do a double-blind study on this, since there is no way to use a placebo -- anyone getting the placebo would know they aren't getting atropine!) However, they used the atropine for quite a number of years, and neither of them has eyes as bad as the four of us older kids. I know: anecdotal only. I just think it's unfortunate that these studies weren't continued, because from what I was able to read, I think they were showing promise. When DD#2 needed glasses by the time she was 8, I talked to the eye doctor about this; she said at the time, it would be hard to find anyone using this any more, and the more recent studies were trying to do the drops only at night, but I haven't looked into it for several years. meh -- Children won't care how much you know until they know how much you care |

Well my kids touch my screen all the time and I have used Windex on it with
a soft cloth for the five years I have had the monitor. We haven't had any problems with it. As far as sitting to close, I don't have a clue but I know that my kids are up to it so they can see what they are doing and typing on the screen. One child has had glasses. However, she had them long before we ever got the computer and the other two children are just fine. I have no studies to back my claim up, just anecdotal. ) -- Sue (mom to three girls) I'm Just a Raggedy Ann in a Barbie Doll World... P.
