This topic is something I've always been curious about. My job requires that I use a large monitor (21" CRT) and eyestrain is an issue after a long day. I take breaks and such, but I'm curious if there is any opinion in the medical field on whether LCD monitors are better/worse for you. It seems like I'm sitting a foot away from a TV all day, which can't be good. Thanks!

Coupe2K,

21' LCD monitor nice! In just about every situation sitting to close to an object you're looking at or studying can cause eye strain and fatigue and with time can lead to poor eyesight. Is there is any way you can distance yourself from the monitor? If you're a foot away as you described above then you are too close. Is the space you're in a confined space? If so, then an LCD monitor would probably be the choice due to the fact that they don't take up the depth as the normal monitors do! I like the LCD screens!

One other important aspect of eye and neck strain to consider while working on the computer. Your eyes should be level with the middle of the screen so you're not looking down.

Thanks! I was actually refering to any health issues with a big CRT electron gun shooting into your head. I probably sit about 2 feet away on average.

Ok, now I understand. If you could be possibly 3 feet or more away that would be better. Yes, the electron gun shooting rays into your head isn't good! Just like those new flat tube TV's (example, Sony Vega or XBR) they really give off alot more damaging rays than the older style TV tubes.

I wouldn't be too worried about the crt tube. Radiation on new monitors is well under "acceptable safety standards". Eye-fatigue though is a worry. Take lots of breaks, and look away from your monitor a lot, this way the eyes will work as they should. Remember humans were "hunter/gatherers" once upon a time, and our eyes are designed to quickly focus to different distances all day long.

OK what do you guys think about this. Is this valid or a bunch of BS? It's taken from this product page:

Computer Vision Syndrome

Strictly speaking, computer vision syndrome is a repetitive stress injury, caused by the act of refocusing on a computer screen image again and again. (Experts compare the repetitive refocusing required of computing to squeezing your hand hard 30,000 times a day.)

Worse, the blink reflex, one of the fastest in the body, is brought to an unnatural standstill when you stare into a computer monitor. On average, you blink 22 times per minute. During reading, the rate decreases to 12 times per minute. At the computer, its cut to just 4 times increasing tear evaporation, doubling the exposure of your sensitive corneas, and resulting in drier, more irritated eyes.

The Trouble With Glare

Generally speaking, there are two kinds of glare:

Direct glare occurs when you sit at your PC and a light shines directly into your eyes. Although amazing in their ability to adapt to poor viewing conditions, your tiny ocular muscles have little chance against this kind of onslaught. Reflective Glare is far less perceptible. Generated by light sources from behind, above or even next to you, it bounces needless illumination onto your monitor. Light from these unexpected sources is just as likely to result in Computer Vision Syndrome (CVS). Experts agree that improving your visual work environment requires a more indirect method.

Indirect lighting reduces glare

Recent studies have proven that indirect lighting reduces glare significantly. Such illumination minimizes eyestrain and the neck and back pain associated with it, resulting in an optimal, more "ergonomically-correct" workplace.

The Solution to Glare-Free Computing

Designed to function as an integral component of your work station. The Eclipse Computer Light is the only available task lighting product that doesn't produce glare. Its long-life, low-energy light source creates a reflected glow that results in a pleasing pool of light over your immediate workspace. Exhaustively researched and laboratory tested.

Nothing in my Diagnosis code books about CVS, but doesn't mean it doesn't exist. That was an advertisement for a product according to the information above. I think there are simpler solutions than buying their product. Here's some other links to check out.

www.doctorergo.com/
www.findarticles.com/cf_dls/m1563/6_18/63636568/p1/article.jhtml (gives some helpful info.)

Anyone else's input would be great to!

Thanks! Those links are great. I'll try some of the tests while I'm at work tomorrow. Still on the hunt for a chair BTW<img src=icon_smile_big.gif border=0 align=middle>
