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 :)

S=1.317h 1/2  S is the distance from to the horizon, h is how much above sea level. The AMS states that the horizon is at minimum 3 miles away.   So for a person whose eye level is 5 ft above sea level, the horizon is 1.317m(5ft)(1/2) which equals 3.29 miles

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.

Hopefully your laptop has a S-Video connection -- if it does, you can buy a special cable to do this.\n\nIt might want to just buy a new monitor, you can get a 15 inch cheap.

yes, i recently started an office job where i look at a computer screen all day (9 hours) and often get headaches and vision sensitivity.  i'm going to ask my doctor if there are any different contacts that i can wear that might be better for this and i am also planning on getting one of those screens you put over your monitor that dims the picture

Well,\n\nhere you can find comparison table:\n\nhttp://michaelbluejay.com/electricity/computers.html\n\nThe main factor is width of screen

ok, well think about what the resolving power means, first.  \n\nit says that if you take 2 point-like objects, and bring them closer and closer together, then your eye (or some optical instrument) will have a lower limit in terms of seeing them as 2 individual objects.  at some distance apart from one another, they will simply blur together and look like a single object or blobby thing.\n\nnow obviously, if the 2 objects are closer to your eye, then you can see them better, so the "distance between objects" is maybe not a very good way of determining your resolving power, because it depends on where the objects are.\n\na distance-independent way of stating the resolving power is in terms of the ANGLE between the objects.  this is the angle formed by the line that goes from object 1 to your eye, and the line that goes from object 2 to your eye.  for any given eye, there is some angular separation between 2 objects below which distinct objects cannot be resolved.  this angle is called the resolving power.  (radians are just a unit of angle, like degrees.  there are 2 * pi = 6.28 radians all the way around a circle.) \n\nso, if you think about it, someone with sharper vision can resolve 2 point-like objects that are closer together than can someone with poor vision.  this corresponds to a *smaller* angle because they're closer together.  so a small value for resolving power corresponds to sharp eyesight.\n\nas for optical or visual acuity, that is simply the reciprocal of the resolving power.  that means that a *larger* value means sharper eyesight.  in a medical context, visual acuity is usually expressed as something like 20/10 (which equals 2) for very good eyesight or 20/100 (which equals 0.2) for poor eyesight.  as you can see, the larger the value, the better the eyesight.\n\nhope this helps!\n\nps - have a look at this website if you need more info:\nhttp://www.tedmontgomery.com/the_eye/acuity.html

How big should my television be? \nWhat most people really mean by this question is, "what size should my screen be?" \nMany studies show that the Critical Viewing Distance (CVD) in simulating a "movie"-like experience yields a viewing angle between 25 and 30 degrees, or about two times the picture width for 16:9 displays. The CVD basically is the maximum distance at which the smallest picture details can be discerned. In a recent article in "Widescreen Review" (V11, N10, Issue 65, Oct 2002), Greg Rogers notes that the limit of angular discrimination for normal vision is 1/60 degree. Using that as an assumption, he provides the following formula to calculate the CVD: \n\n\nCVD (in PH) = 3438 / (# of pixels per PH)\n\nwhere PH is the picture height in pixels. If you do the math for a standard NTSC television, this generally means that you're going to need to sit back about 7 times the picture height in order to reduce the appearance of scan lines. Unfortunately, this also severely limits the viewing angle. \nAnother problem is that manufacturers use the diagonal measurement of a screen in advertising. This makes the screen sound much bigger than it really is. It also makes it hard to figure out the proper ratios when buying a new television. \n\nHere are a couple of simple multipliers to use in the calculation of seating distances from the screen. Any distance less than the optimum allows the viewer to see presentation artifacts and can cause eye and muscle fatigue. Also, don't sit too much farther away than indicated or you're wasting the screen real estate. \n\nMy ratios are derived using information that normally applies to the height of a television screen. Since most manuals and stores have no idea how tall a screen is (and most people don't carry a tape measure), it is easier to use calculations that rely on the diagonal measurement. The diagonal size of a screen is always available in the marketing literature. \n\n\nCalculating the optimal seating distance using screen size\nFor standard televisions (4:3 aspect ratio, 480i signal)\nMultiply the diagonal measurement (in inches) by 4.3. \nFor HDTV (16:9 aspect ratio, 1080i signal)\nMultiply the screen diagonal measurement (again, in inches) by 1.57. \n\nCalculating the optimal diagonal screen size using the seating distance\nFor standard televisions (4:3 aspect ratio, 480i signal)\nDivide the distance you sit from your television (in inches) by 4.3. \nFor HDTV (16:9 aspect ratio, 1080i signal)\nDivide the distance you sit from your television (in inches) by 1.57. \nYou can use these numbers to avoid being sold a screen that is far too large for your seating area (the most common mistake in television purchases). \n\n\nSizing a 16:9 set to replace a 4:3 standard television\nIf you're buying a 16:9 set to replace a 4:3 set, multiply the diagonal screen size of your current set by 1.22. This will give you the 16:9 diagonal screen size you would need to buy such that the height of the new screen is no less than your existing screen. However, you should always use the seating distance as the ultimate decider. If the seating calculation indicates a smaller screen than the screen height calculation, then get the smaller screen.

how about adjusting the contrast/brightness settings first. 3M makes anti glare shields if needed. sunglasses would be cheaper.

the images on a computer screen are "hard" or "fixed" images.  Staring at the screen for long periods of time can damage your eyes.  Give you eyes a break by looking out the window for 5 minutes every hour.  Good luck

Basically:\n\nScreen at eye level, or just below.\n\nElbows rest at a height that makes them be bent at 90 degree angles.  Typing is not uncomfortable.

Im afraid my eyes arent good enuf to see that far... Its an unaswerable question

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.

Well if I've worked this out correctly and assuming that you'll be watching HDTV on this screen then you should be looking at approx 42".\nFormula is:\n\nFor Cable Antenna or Video tape Multiply the number of feet between you and the screen by 4 inches. \n\nFor DVD or Satellite Multiply the number of feet between you and the screen by 6 inches. \n\nFor HDTV Multiply the number of feet between you and the screen by 7 inches.\n\nHope this helps

It's not bad deal, Good contrast ratio 700:1 good response time 8ms.  The viewing angle isn't the best @ 150º horizontal 135º vertical; but if your just sitting infront of the monitor you'll never see the difference.  Good price for a 19" too Check out http://www.pricewatch.com/brands/monitors/sceptre_technologies-2.htm\nCostco has it for cheaper.

PCs and monitors are very well shielded. You don't need to worry. The main thing to worry about is eyestrain and repetitive strain injury.\n\nMake sure that you know - and practice (!) - the basics about sitting correctly, using the keyboard and mouse correctly, using the eyes correctly and taking frequent breaks.\n\nRSI: http://eeshop.unl.edu/rsi.html\n10 Steps to good computer use: http://www.spineuniverse.com/displayarticle.php/article1410.html

Not yet...\nThe solution is to use Holographic projection.\nYour screen would be the same as a hologram, and, instead of showing a picture, would have to be "written" by "scattering vectors".  This, in theory, would allow you to see THROUGH the screen a scenery in 3D (behind!), providing the processor can trace scatering vectors fast enough.\nTo get it IN FRONT of the screen is more complex.\nLet's first get monitors "see through" in 3D!
