While most people using Everything2 sit at a computer to do so, research has shown that many of these people do not sit correctly, or work under suboptimal conditions. The result is not unusual: Carpal Tunnel Syndrome, back and neck pains, eyestrain, and headaches. The strange thing is that many people simply accept these (often minor) aches and pains as a result of using a computer, when in fact these annoyances are easily avoidable with a little planning and effort. The following sections cover various different aspects of sitting at and using your computer, and should, if followed correctly, make your computer experience far more pleasant.
Placement of your computer in the room
One of the major cause of eyestrain when using a computer can be attributed to glare. Therefore, your computer screen should not be directly next to or directly opposite a bright light or window. Reflected glare can make it difficult to make out what is seen on the screen, and having your eyes constantly adjusting to a bright light directly next to your screen can lead to tension headaches. If necessary, move the light source to another part of the room or invest in heavy curtains. Anti-glare screens can help, but tend to make the text on the screen fuzzy and difficult to read. If you are in an office situation, then check with your IT department before moving equipment - moving equipment without permission can constitute a breach of your IT policy. If necessary, speak with your manager, as new curtains are often a small price to pay for increased productivity and decreased medical fees.
Placement of your computer on your desk
Your computer (particularly your monitor, keyboard and mouse) should be at a comfortable height for you when you sit down. This means that your elbows are just above the desk when you sit down at it, and your monitor should be raised if necessary so that you look at it straight on, without having to look down or up. Your feet should be able to rest comfortably on the floor. Your computer should be square with the edge of your desk, so that you do not have to lean in any direction to use it. Your keyboard should not be obstructed with bits of paper, and you should use a mousepad to keep your mouse moving smoothly. The use of cable ties to tidy up the cables running around and behind your desk can make a big difference to the neatness of your work area. If cables are a big problem, wireless keyboards and mice are relatively inexpensive, and newer models use up very little battery power, meaning that a single set of batteries can last for months at a time. When buying a keyboard, try and get one with a wrist rest, as these do cut down on wrist problems.
Making your screen easier to work with
A fuzzy, poorly looked after monitor is not pleasant to work with, and once again, can cause eyestrain. However, there are a number of ways to clean up your monitor, and make it easier to work with. The first thing to remember that while monitors get fuzzy or blurry with old age, this can be fixed by most TV repairmen - in many cases, monitors have a small dial inside them that can be adjusted for sharpness and clarity. While this will not help all monitors, it will make a big difference to those it can. Your monitors refresh rate can also affect you over a period of time - this can be changed under Windows by:
- Clicking on Start.
- Clicking On Control Panel (or Settings and then Control Panel, depending on your version of Windows).
- Double Clicking on Display.
- Clicking on Settings, at the top right.
- Clicking on Advanced, at the bottom.
- Clicking on Monitor, at the top.
- Selecting a refresh rate higher than 60 Hertz. Try and select the next highest refresh rate, as some very old monitors can be damaged by trying to display a refresh rate that is too high.
- Clicking on OK at the bottom.
- Your computer will attempt to display the selected refresh rate. If your screen goes dark, wait for a few seconds, and your computer will revert to the original setting. If you can see the screen clearly, then click on OK.
- Click on OK, and then OK again.
- Close the Control Panel.
Under Mac OSX, you can:
- Click on System Preferences in the dock.
- Click on Displays.
- Adjust the refresh rate.
Bear in mind that some monitors (and video cards
) cannot work at anything higher than 60 Hertz. It is for this reason, among others, that I recommend to anyone buying a new computer that they purchase the best monitor they can afford, as a good quality monitor will pay for itself over and over again. The next step is to decrease your brightness
- many people turn the brightness and contrast to maximum on their monitor, which makes the screen easier to see, but also makes the monitor too bright, leading to eyestrain. If the computer is in a reasonably dark room, and is not reflecting any glare, you will find that you can turn the brightness down a long way and still find any text very visible and easy to read. In general, your contrast should be set to maximum, but if you have turned your brightness all the way down, you can decrease your contrast a little bit as well. The end result should initially be a little difficult to make out, but you will find that your eyes quickly adjust, and your monitor will be much easier to work with for extended periods of time. Furthermore, when working on your computer, try and look away from your monitor every fifteen minutes, as research has shown that this helps prevent short-sightedness
. One last note - although monitors are shielded, it is not advisable to leave them next to magnetic
sources for extended periods of time, as these can cause your monitor to display strange colours in different parts of the screen. Please note that while computer speakers
are magnetic, they are usually shielded as well, and do not constitute a major risk. Subwoofers
are the exception to this. If this has happened to your monitor, speak to a television repairman or your IT technician
A clean, uncluttered computer is far more pleasant to use. Try and keep your monitor and keyboard clear of Post-Its, bits of paper, cards and so forth. The same applies for your desktop - if you remove unneeded icons from your desktop, and use a well thought-out directory structure for your documents and files, you will be able to find things much easier, and be more efficient as a result. By using a damp cloth and a little soap or detergent, you can clean your monitor, mouse and keyboard, which can improve the general cleanliness of your office or workspace. A noisy computer can also be an irritation - speak to your computer technician, as squeaky bearings in fans can be oiled, and dust can be cleaned out from inside your computer, making it much quieter. If your mouse is jerky and difficult to move around the screen, then you can clean it by turning it over, removing the cover and mouseball, and gently cleaning the dust and grime from the rollers inside with an earbud or small piece of cloth. Better yet, you could buy an optical mouse, which has no moving parts, and works on any surface that is not reflective. If your computer stops responding for seconds at a time, or is much slower than usual, especially when connected to the internet, you could have spyware or adware installed on it. Details on this can be found at Malware: A Layman's Guide. If your keyboard sticks, or does not work properly, ask your IT department to replace it or buy one yourself - keyboards are cheap, and a good quality keyboard will, like a good quality monitor, pay for itself over and over.
While the above steps constitute a fairly comprehensive guide to help make your computer experience a pleasant one, it is by no means complete, and will depend heavily on your needs. If in doubt, speak to a chiropracter or doctor, and if possible, with your IT department or technician.
