Nowadays, I am using computer for almost 6-7 hours daily. My mum keeps screaming ," You'll blind yourself. And I won't get you spectacles, mind you!". Couple that with the fact that I am a biology student ; you have a perfect case of hypochondria.

Now, first off, I wish to ask if exposure to computer has affected anyone's eyesight?

Right now, I do not have a radiation-proof screen on my LG PC. So, am I at risk?

The worst that can happen is temporary eye strain.

They settled this issue quite nicely on an episode of Dr. Know. There are no long term problems for your eyes from looking at tv/computer screens.

Exposing yourself to your computer is a personal issue and should only be done in the privacy of ones own home.

Uh....I'm not speaking from experience on this.

(No, really, I never flashed my puter! Honest! Has anyone seen my eyeglasses?)

So, just for the record, my mom was full of crap when she told us not to sit so close to the TV, right?

Whether it's bad for you or not, if you develop eye trouble in the future and need glasses, your mum will blame the computer and nothing you/we say will change her mind. Mine always swore I'd need glasses if I didn't turn the lamp up to broil when I was reading... so what happened? I turned 40 and my eyes started going down hill. All mom could say was, "See? You shoulda listened to me!"

It's their job. ;)

It does cause eye fatigue. There is no evidence to date that shows computer screens are harmful, but who knows what will pop up in the future. One day something is safe and the next it causes cancer.

I believe in time there will be evidence proving computers are harmful. However, I am a cynic when it comes to technology; it helps and harms us.

Close computer/monitor work can damage your eyes. What you need to do is make sure the computer is where you can look across, or down to it--not above you eye line. And do take breaks, ensure you do look off into the distance, walk, look at the horizon dayly. You may laugh but 3 months doing video analysis with poor picture quality and a small screen mounted too high took me from 20/20 to 16/20 as well as giving me severe headaches. Since I finshed that job my eyes sight has been gradually *improving* again.

I used to read so much that I started having trouble seeing and got frequent headaches. So I had to get reading glasses, and they 'relax' my eyes when I'm reading or at the computer.

I work on a computer for 8 hours a day and then I come home and work on my lap top (usually in front of the TV) for the rest of the night. My eyes remained the same for 20 years and only recently have started to change. But I believe it's more of an age thing than an eye strain thing.

My eye doc complains that I put "18 hours" on my annual checkup question "how many hours do you spend in front of a computer."

He's been complaining about it for 12 years. No change in eyesight.

i seem to remember hearing it's not a good idea to focus your eyes at one distance only for long periods- to maintain elasticity, eyes should be often shifted to different focal distances.
i dunno- but could it hurt to look at a distance once a minute while on the computer for long periods?

usual disclaimer in effect-

I worked for an IT company for 18 years, a good chunk of that time spent on CAD systems. The first displays (back in the early 1990s) were like huge B/W 25" TVs with dazzlingly bright geometry lines that seemed to sear afterimages onto my retinas for hours. Coupled with bad office lighting conditions (glaring overhead halogen strips that couldn't be turned down, just off, which made the displays appear even brighter) this was a recipe for severe eye strain that affects me to this day. I can only stand to use a laptop/PC (non-glare TFT displays, with nice pastel background) for maybe 20-30 minutes at a time before I get niggling eyestrain pains behind my eyes and have to get up and walk away. If I keep working, the eyestrain develops into migraine-like headaches, cue lying down in a darkened room with a black sock over my eyes until the pain abates an hour or more later. It's killing my writing, this has been the worst year ever for me. Yeah, been to specialist opticians, clinics, etc. alas their suggestions just made things worse. The source of my problems, I'm pretty damn sure, is having my eyes strained to hell and back by those old displays and crap lighting 'way back when. If only they'd developed TFT technology 15 years earlier...

To make you a vampire they have to suck your blood. And then you have to suck their blood. It's like a whole big sucking thing. Mostly they're just gonna kill you.

Derek,

If there were a way to change the background of everything you see on your computer screen from a stark white, to a pastoral light blue as you can do with Microsoft Word, that would help.

I havenít found a way to do it on Internet Explorer because there isnít a way to do it yet.

Iíve spent most of my life first looking through an Electron Microscope at Radiation Inc. designing and building computer chips, then at a computer screen at the space center for 45 years. I am blind in one eye and developing cataracts.

Hey Jerry, wow, and I thought I had problems with MY eyes!

I've got my Windows background color set to a nice pleasant eggshell green. As you probably know this is adjustable by right-clicking on any blank area of the desktop, selecting Properties from the little pop-up box, then select Appearance tab, which brings you to Display Properties. From here, select the Advanced button, select the Window Text area, select the Color 1 arrow, select Other button. You can select from the color palette or manually enter RGB (Red,Green,Blue) values. My RGB is set to 122 188 122 giving me a soothing shade of green, the least irritating color to the eye, so I'm told.

Microsoft Word, Notepad and other programs take the Windows colors as default.

Internet Explorer and other browsers let you adjust colors from inside the application, e.g. select Tools / Internet Options / Colors button / tick Use Windows colors / click on OK, click on Apply, click on OK -- and IE should now display the background color you prefer.
Software update: in IE7 select Tools > Internet Options > General tab > Accessibility button > Tick "Ignore colors specified on webpages" to use Windows system colors instead.
And if you want to specify your own default font size, tick "Ignore font sizes specified on webpages"
- If using Firefox, select Tools > Options > Colors > Tick "Use system colors"

If none of that makes sense, say so and I'll type slower. :)

PS - if you're playing around with color settings, remember to take note of what they were before you started playing, just in case you don't like the result and want to change back to what you had before.

PPS - you know that Windows comes with pre-defined color and text schemes? In the Display Properties window, you'll see "Color scheme" and "Font size" options, if you select the arrows to the right of each field, you'll see lists of available schemes.

My usual working position from the screen is some 55 cms away from it. Is that too close?

Have you guys actually ever measured the distance ?

Arm's length is good for me. When I reach out, my fingertips just touch the screen. But that's my ideal focal range, with glasses on. I guess everybody must be different.

Look Dave, I can see you're really upset about this. I honestly think you ought to sit down calmly, take a stress pill, and think things over.

I went from a CRT monitor to an LCD monitor a little over a week ago, and the improvement in my vision is noticable. I used to see spots when I looked away from my old screen, and I'd end the day with a headache. At times my eyes would sting. With the LCD I've had none of those problems. It's downright pleasant really :)

Where I work, people will scream bloody murder and refuse to work until the thing is installed so they can go back to slumping their shoulders and craning their necks to see the screen which, of course, MUST be elevated on some sort of riser.

The typewriter didn't produce a generation of hunchbacked secretaries with chronic neck pain because the placement of the keyboard and carriage forced you to sit up straight to do your job.

Progress. Feh!

Nose prints all over my screen are fine with me SpiderGa.

Derek,

I’ve had all along the background screen colors I needed on windows desktop, word, and most all of the other applications, but on my Microsoft Windows XP professional, I’m not able to apply my selection I need when I chose to apply it for windows background. Apply just isn’t highlighted as a selection. I tried it before and again just now. It just won’t engage. I have my desktop with a nice dark blue hue to it.

Thanks.

Oh, my windows pro is an OEM version, I built my own computer from scratch and in order to use the OEM version, I had to have bought the Mother Board (With the CPU I installed) from newegg.com in order to qualify for the OEM version.

I bought a
AMD Athlon 64 4800+ “Toledo” 2000MHz 939 Dual Core Processor, an ASUS A8N-SLI Premium Socket 939 NVIDIA nForce4 SLI ATX, an ASUS EN7600GS Geforce 7600GS 512MB PCI Express Video Card, 2GB of CORSAIR 184-Pin DDR SDRAM DDR 400 (PC 3200) memory, a Western Digital Caviar 250GB SATA 3.0Gb/s Hard Drive, and a SAMSUNG LCD Monitor.

I put it together in a Rosewill Black Screw-less Dual 120mm Fan ATX Mid Tower Case and installed an Antec TruePower 2.0 TP2-550W Power Supply. Gota brag a little on that system.

You techno-slut, stop it, you're turning me on! I bet the casing is shiny black leather with spike heels.

Sure is odd about the apply button not working. Who can predict the random workings of Windows XP? On my little laptop, adjusting the RGB in Display Properties as described above, then selecting Use Windows colors within Internet Explorer, obviously does the biz for me and gets rid of the eye-straining default colors.
