Does looking at a computer monitor hurt your vision after awhile?
608196
Yes, it can harm your vision.  Not only by eyestrain.  \n\nWe are built to function binocularly (focusing on things with both eyes in a wide spectrum).  When we focus so intently on the screen, our eyes get "locked" into that focus.  Over time, it can diminish your focusing ability, and thus change your eyesight.  \n\nYou should look away from your screen every 10-15 minutes and focus on something far away to keep your eyes flexible.

My eye doctor told me one of the problems is that, when you work on a computer, you don't use your eyes to focus at different distances the way you do in other types of work.  He recommended looking across the room at a clock or reading from a paper or some other way to exercise focusing your eyes at different distances. Set a timer to make sure you do it regularly.  I also think working long hours on a computer may be harmful because the computer screen is a light source and you're looking right at it.  It might help to have a lot of light in the room to counter the effects of that.

move your monitor slightly side way...\n\n\nas long as you still can see what your doing...\n\n\nwhether your a near sighted or farsighted... then you wont have to move backwards to stay away from direct rediation...\n\n\nheheheheh :)

Isolation from actual human to human contact. \nSloppier hand writing\nInability to spell (spell check does it for kids)\nInability to resolve conflict face to face.\nCan cause arguments because people can't "read" the other person's IM, email etc and think that someone is ticked when the other isn't.\n\n\nps: Does the person above me really think she/he is receiving diseases from the minimal amount of radiation from the monitor???? . Is working with computers as harmful as watching TV for long periods of time? How harmful are the radiations from the computer as compared to that caused by TV?\n\nA. Modern computer screens emit very little radiation and are very safe. Issues with regards to eye strain because of computer usage (Computer Vision Syndrome) are mostly due to bad contrast/excessive or poorly illuminated screens / background illuminations / posture / positioning of the monitor and ocular conditions such as dry eyes / allergic conjunctivitis, uncorrected refraction errors esp. astigmatism & convergence insufficiency. \n\n\nIf these aspects are looked at carefully, computer usage & TV viewing, even over long periods, is not harmful. The screens should be flicker free with high refresh rates (Hz). It is also recommended that a few minutes of rest be taken after 30-40 minutes of use.

No, no, no!  That's a myth!  Gazing at anything too closely might cause eye strain, but only if a person is far-sighted and has a hard time seeing items up close.  Even if the eyes are strained, that's a very temporary condition, and more of an annoyance than a health problem.

No. Don't have to worry since data isn't stored permanently. \n\nBut don't buy a monitor without seeing it plugged in first so you can see if all the pixels can be lit.\n\nCheck for coffee/drink/water stains at the top too. Some knuckleheads keep drinks or plants on the top of older/larger CRTs.\n\nGood luck.

It's not recommended to do that, because the resolution of a TV screen is much lower than that of a PC monitor.  Your eyes will go bad pretty quickly.\n\nHowever, if you're wanting to do that, visit Circuit City or Best Buy.  There are a number of small, inexpensive (under $50) gadgets that will do this for you.

Dcreasing the refresh rate increases flickering, increasing eye strain, but few people notice any change above 60-72 Hz.

Nope - turn off the monitor, though, because that consumes a lot more power than the computer itself. Leaving your computer on is actually even better for it, because most failures happen when you turn it off and back on.

Yes- computer vision syndrome, or CVS, a complex of eye problems provoked by hours of staring at a computer monitor. Anybody who spends even two or three hours a day on a computer risks developing CVS. The symptoms of computer vision syndrome include headaches, redness, contact lens discomfort, blurred vision, light sensitivity, dry or burning eyes, focusing difficulties and sometimes pain in the back, neck and shoulder. Anyone experiencing these symptoms should consult a healthcare or vision specialist.\nAspects of the design of the computer video display - such as screen resolution and contrast, image refresh rates, flicker and screen glare, as well as working distances and angles - all can contribute to symptoms. The condition apparently is not permanent and improves when short breaks are taken from the screen. Commercially prepared eye drops are available to alleviate symptoms. \nYou can reduce the effects of CVS by:\nPositioning the monitor to avoid glare from windows and light sources. Place a filter over the screen. Optically coated, contrast-enhanced, anti-glare filters provide clearer views than mesh filters. \nPosition the monitor 20 to 28 inches away from your eyes. The center of the screen should be 4 to 9 inches below eye level. Any factor that causes you to tilt your head backward or lean forward to see the screen properly can lead to neck, shoulder and back pain. \nRest your eyes. Every 20 minutes or so, look out the window, water a plant, or meditate for 30 seconds. Take a 10 to 15 minute break after two hours of steady computer use. \nRemember to blink. Most people blink less when using a computer, which is believed to be related to the frequency with which a screen is electronically refreshed. A higher refresh rate provides a clearer screen and less eyestrain.

Any type of screen will worsen your eye unless you are careful to give your eyes a break.\nThere are a few tricks you can do to help alleviate problems.\nThe quickest way is to focus on different objects. If you are lucky enough to have an office with a view. Look outside and focus on objects far away every few minutes. (Just enough to focus on for a few seconds to let your eyes 'STRETCH')\nKeep brightness down, too. Staring at a good monitor, you rarely need to crank up the brightness on it to read accurately.\nAbove all. Pay attention to your body. If you start having trouble focusing...or getting headaches, it is time to walk away and get some distance from the cube.

I have the same problem, I just found out I need glasses for it, but also for distance and stigmatism.  Nice combo, basically I need bifocals at the age of 25. :(  But the doc did say the computer is bad for the eyes, so every 20 minutes, you should look 20 feet away and look at that place for 20 seconds. 20/20/20.  It is supposed to help your eyes refresh.  Sleeping a full night helps too, don't forget to blink, use drops if needed.  The problem with computer screens is that each tiny pixel in the screen is moving on its own, almost flickering.  We can't see it because the flicker and pixels are so so small, but the eye needs to use more energy to focus on that screen, thus damaging your eye sight.  Get glasses, computer glasses, they are supposed to help, I am waiting to buy mine because I don't have eye insurance in 2006, but will sign up for it in 2007.

Honestly no. Scratches on an lcd monitor are permanent. If you hear about anybody selling products that will magically make the scratches disappear, I guarantee you that it is a scam. If the scratch is serious, then the pixels around the scratched area are also destroyed, meaning the individual light particles can no longer be correctly be displayed in that area.

You wouldn't ruin your eyesight for years and years. Modern computer screens are low-radiating.\nThat's just something parents say. There are other reasons why they don't want you infornt of the PC all day....\n\nAnd Dar, you also asked about porn, so I see a connection here. If you watch porn on the PC - I can see why they don't want you there all day, right?

use a screen glare reducing sheet, wearing eye glasses. cold water on eyes every little while.I have an LCD flat screen monitor and it helps a little bit, but try the other things, pick up some cheap non prescription reading glasses and wear these all the time at the computer.

Make sure not to sit close to it,and take frequent breaks by resting your eyes...Look away then sit with your hands cupped over your eyes for 2 mins,then go back to using computer.Do some eye exercises...look up then to the side then around then down for 30 seconds each.

I used to get this. First of all make sure the light on the monitor isn't too bright, there should be a switch that adjust the light. Also I find if the monitor is too close I get pains behind my eyes. Move the monitor a reasonable distance away for you. Hopeful when you've made a few adjustments you should be OK. If this is thw first time you've used a computer it does take a while to get used to it.
