I work at least 8 hours a day in front of the computer, inside a cubicle! I am proud to say that I have been in this business (total sedentary life) for 5 years. I have no carpo-tunnel and no pain! The secret to this is : Ergonomics. If you google this word, it will give your references...you have to sit and type properly and also stretch! It's very important to take breaks and stretch your arms, back and legs. If you do this right you will not have pain, it's also important to keep hydrated. Good luck!

how about changing your work study habits instead. Try a place thats quiet with no distractions, get up often and stretch or take a short walk in fresh air every 30-45mins. Don't snack while working change subjects or projects if you find yourself stuck or losing focus and then come back to it. There are lots of herbal and otc's that make claims but do any of the really work or cause more harm or just waste your money.

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

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.

just leave it on.\n\nthat's my answer.  but you do have to edit your power preferences so your computer doesn't turn off after 2 hours of non use.  other than that, I don't know.

Have you been on the computer for a long while?... I use to get MASSIVE headaches and I found out it was because I was looking at a computer screen for too long. Try looking away and focus on something across the room ever 15 minutes or so.

it is very possible that spending a whole lot of time on a computer can cause damage to your eyes. it strains your eyes and can wear them out. my mom always says that i shouldnt spend more than an hour or so online without letting my eyes rest. that said, reading and doing other activities like that can also strain your eyes.

I think the biggest obstacle for you concerning this is watching what you eat.  It is shown that people who work at desks and at computers all day tend to snack a lot, often on high carb foods.  Snack on things like veggies and watch what you eat, as well as take a vigorous lunch time walk and I think you will keep your body in fine shape.

Drink lots of water and avoid caffeine.\n\nDim the lights, don't play on the computer or watch TV.  Just turn on the radio to something relaxing and close your eyes.

Computers can blur your vision...\n\nSixty million people suffer eye problems due to working on computers, and the number is rising by a million every year.\n\nComputer 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.\n\nAll 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 p[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.\n\n\nComputer 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.\n\n\n\nTips to prevent CVS:\n\n1.Blink frequently to lubricate the eys & prevent dryness – more critical for contact lens wearers.  A conscious effort     should be made to blink frequently.\n2. Take 2-4 minute breaks ever half hour – don’t strain your eyes looking at your computer.\n3. Use anti-glare spectacles preferably with grey tinted lenses, which is a neutral absorber and can filter unwanted effects     of certain colors.\n4. Position the monitor 20-26 inches away from the eyes\n5. Keep the computer screen at your eye level or 5 degrees below the eye level.\n6. Keep the monitor, CPU, keyboard, mouse and other peripherals in easy-to-reach places so as not to strain any other     body parts.\n7. Black characters on a white background are usually best.  Avoid dark back grounds and the size of the text should be     three times the size of  the smallest text you can read.\n8. Arrange light source to minimize glare and reflections on the screen.\n9. Reduce the amount of lighting in the room to match the computer screen.\n10. The use of contact lens re-wetting drops is recommended periodically during the day while using the computer     screen.\n11. Use anti-glare computer screen.\n12. Keep your computer screen free of dust.
