how many years can you stare at a computer screen before it really does damage to your eyes?

im starting to feel effects of it, try to use a computer screen (like a little net thing) over it, sit back, and give your eyes time to rest every hour or so. \n\n\n\nalso lcd screens are a lot better for continuous use than regular monitors. and don't sit close to the computer, try to sit a few feet back.

It depends on when you received the caution - as a youth or adult and it's not three years!\nAs an adult it's five.

no, it should be more than five years to cause irreversable damage.  you may want to take the vitamin coq 10 though.  it will bring high blood pressure down and help dissolve small blockages.

On older CRT monitors (resemble a TV), having the same image on-screen for a long time would cause it to start etching into the glass. This was called "monitor burn".\n\nUsually happened worst on monochrome displays; almost never happens nowadays, and can't happen to LCD displays.

you can buy computer screen protector, it reduces uv rays from your pc. its the best way of chattin'/surfing for log hours without using glasses/lenses.\nyou can also rest your eyes for 15 minutes after every hour of surfing.

I think your monitor is about ready to die.

Several years, depending on what sort of things you do with it. Theoretically, for just word processing and browsing the Internet, a computer will last as long as it physically holds together, which will probably be three to four years. My parents, for example, just replaced their computer after 6 years, simply because they wanted something with Windows XP instead of Windows 98.\n\nIf you're more interested in high tech gaming (online games, or regular games like Doom 3 or Half-Life 2), you'll probably at least upgrade your RAM or graphics card every year to 18 months.

depends on how much you use your pc.. if you use your computer throughout the day, keep it on all day and turn it off at night.\n\nTry this-\nscreen saver on after 15 minutes of inactivity.\nstandby after 30 minutes of inactivity\nhard drive off after 45 minutes of inactivity

Surgery takes about 30 seconds.  Afterwards your eyes will age/weaken as they naturally would.  I had it 7 yrs ago still 20/15 - better than perfect!  Of course there is a miniscule chance they will screw it up and you'll go blind.  My vision was pretty bad and I hated glasses and was sick of contacts and the risk was worth it to me.  It is the best medical thing I have ever had done.

Yes,it will effect ur eye vision it called CVS. All those hours we spend at the computer, straining our eyes, causes a condition known as Computer Vision Syndrome (CVS). CVS is characterized by eye strain associated with prolonged use of computers, with symptoms which include eye fatigue, dryness of the eyes etc. A number of investigations have indicated that these symptoms occur in 75-90% of computer users.Computer images are created from thousands of tiny dots so there is no distinct image for your eye to actually focus on. You have to focus and refocus to keep the images sharp and after two hours you end up with the same kind of repetitive stress on your eye muscles as that caused by the keyboard on your wrists.Make sure your visit the optometrist regularly to get your eyes tested for Computer Vision Syndrome. He or she may prescribe special glasses and/or an anti-glare screen filter or make other ergonomic recommendations.

It should be about a week that you experience discomfort. It will be quite a bit longer, say 3-4 weeks, before you wear eye makeup again.

Hi there,\n\nThe viewing distance from the screen to the eyes should be seventeen to twenty-six inches. \n\nSome eye relaxation exercises would also help.\n\n:)

This question has two answers. The lifespan of the pc (ie. how long until it breaks) and useable lifespan (ie. how long it will be worth using before you need to upgrade or replace it).\n\nNormally a PC can run for anything up to 10 years. In South Africa (where I live) many people still own Pentium I pc's. They work (still) and run Windows 98 SE. But these PC's are of no use to a reputable business because they cannot handle the workload of Windows XP or CorelDraw. \n\nSo even if a PC can be 25 years old, you probably won't want to use it after more than 3 - 5 years.

You may always extend the warrant; however, the typical life on hardware is 6 years on average (the CPU, at least).\n\n1.  Put your computer in Stand-By mode if you're not using it and don't shut it down a lot unless you're not going to use it for 2 plus hours.  Cold boots hurt the computer.\n2.  If the DVD drive is a reader and not a burner, you are good to go--no worries.\n3.  Keyboards are interchangable (unless USB, then you'll need the drivers).  However, some have extra fancy buttons like "Internet"  "E-mail", so forth that a program must control.\n4.  Anti-virus plus Microsoft (if it's XP) spyware programs, such as Windows Defender and Ad-aware.  All hard discs have a chance of crashing--not always the data being corrupted, but the circuit board (controller) on it frying.\n\nNotes:\nGet 512(+) RAM, if you can.\nSerial ATA hard drive.\nDual core processors at about 2.6 GHZ.  (I'm not sure of Professional x64 compability with dual processors, but I'll figure it out--contact me later if you want info' on that: intervain@hotmail.com)\nnVidia grahpic cards:  http://pcworld.com/resource/browse/0,cat,1050,sortIdx,1,pg,1,00.asp\nLook through that, not only the value but the power ones--it sounds like you love games.\nDefragment your PC every week, Mr. Gamer.

About a week. bruising proceeds Red-Blue-Green-Gone. So when you get a greenish tint to the bruising around the eye, you know you're nearly there :-)\n\nI would advise injury prevention by avoiding the item or person that gave you this problem.
