Tips for Computer Eye Strain Relief. By Gary Heiting, OD, and Larry K. Wan, ODSee also. Computer vision syndrome FAQ . Studies show that eye strain and other bothersome visual symptoms occur in 5. These problems can range from physical fatigue, decreased productivity and increased numbers of work errors, to minor annoyances like eye twitching and red eyes. Here are 1. 0 easy steps you can take to reduce your risk of computer eye strain and other common symptoms of computer vision syndrome (CVS): 1. Get a comprehensive eye exam. Having a routine comprehensive eye exam is the most important thing you can do to prevent or treat computer vision problems. If you haven't had an eye exam in over a year, schedule a visit with an eye doctor near you. According to the National Institute of Occupational Safety and Health (NIOSH), computer users should have an eye exam before they start working on a computer and once a year thereafter. During your exam, be sure to tell your eye doctor how often you use a computer at work and at home. Measure how far your eyes are from your screen when you sit at your computer, and bring this measurement to your exam so your eye doctor can test your eyes at that specific working distance. Use proper lighting. Eye strain often is caused by excessively bright light either from outdoor sunlight coming in through a window or from harsh interior lighting. When you use a computer, your ambient lighting should be about half as bright as that typically found in most offices. Eliminate exterior light by closing drapes, shades or blinds. Reduce interior lighting by using fewer light bulbs or fluorescent tubes, or use lower intensity bulbs and tubes. If possible, position your computer monitor or screen so windows are to the side, instead of in front or behind it. ![]() Blue Screen Vista with problem details.

Gary Heiting's top 10 tips for avoiding eye strain when working at a computer. Fortunately, there are various methods to solve blue screen errors in Windows 7. You should be able to log in to your system (after a system crash due to a BSOD) to. Many computer users find their eyes feel better if they can avoid working under overhead fluorescent lights. If possible, turn off the overhead fluorescent lights in your office and use floor lamps that provide indirect incandescent or halogen lighting instead. Sometimes switching to . But even full spectrum lighting can cause discomfort if it's too bright. Try reducing the number of fluorescent tubes installed above your computer workspace if you are bothered by overhead lighting. Minimize glare. Glare on walls and finished surfaces, as well as reflections on your computer screen also can cause computer eye strain. Consider installing an anti- glare screen on your monitor and, if possible, paint bright white walls a darker color with a matte finish. Again, cover the windows. When outside light cannot be reduced, consider using a computer hood. If you wear glasses, purchase lenses with anti- reflective (AR) coating. AR coating reduces glare by minimizing the amount of light reflecting off the front and back surfaces of your eyeglass lenses. Upgrade your display. If you have not already done so, replace your old tube- style monitor (called a cathode ray tube or CRT) with a flat- panel liquid crystal display (LCD), like those on laptop computers. LCD screens are easier on the eyes and usually have an anti- reflective surface. Old- fashioned CRT screens can cause a noticeable . Even if this flicker is imperceptible, it still can contribute to eye strain and fatigue during computer work. Complications due to flicker are even more likely if the refresh rate of the monitor is less than 7. Hz). If you must use a CRT at work, adjust the display settings to the highest possible refresh rate. When choosing a new flat panel display, select a screen with the highest resolution possible. Resolution is related to the . Generally, displays with a lower dot pitch have sharper images. Choose a display with a dot pitch of . Flicker is not an issue with LCD screens, since the brightness of pixels on the display are controlled by a . Hz) noted on an LCD screen, don't worry — this refers to how often a new image is received from the video card, not how often the pixel brightness of the display is updated, and this function typically is not associated with eye strain. Finally, choose a relatively large display. For a desktop computer, select a display that has a diagonal screen size of at least 1. Adjust your computer display settings. Adjusting the display settings of your computer can help reduce eye strain and fatigue. Generally, these adjustments are beneficial: Brightness. Adjust the brightness of the display so it's approximately the same as the brightness of your surrounding workstation. As a test, look at the white background of this Web page. If it looks like a light source, it's too bright. If it seems dull and gray, it may be too dark. Text size and contrast. Adjust the text size and contrast for comfort, especially when reading or composing long documents. Usually, black print on a white background is the best combination for comfort. Color temperature. This is a technical term used to describe the spectrum of visible light emitted by a color display. Blue light is short- wavelength visible light that is associated with more eye strain than longer wavelength hues, such as orange and red. Reducing the color temperature of your display lowers the amount of blue light emitted by a color display for better long- term viewing comfort. For computers running on a Microsoft Windows operating system, display settings can be adjusted in Control Panel. For an Apple computer, display settings are found in Systems Preferences (in the Applications folder in Finder). In some cases, the color temperature of a desktop computer monitor is adjusted on the display itself. Blink more often. Blinking is very important when working at a computer; blinking moistens your eyes to prevent dryness and irritation. When working at a computer, people blink less frequently — about one- third as often as they normally do — and many blinks performed during computer work are only partial lid closures, according to studies. Tears coating the eye evaporate more rapidly during long non- blinking phases and this can cause dry eyes. Also, the air in many office environments is dry, which can increase how quickly your tears evaporate, placing you at greater risk for dry eye problems. If you experience dry eye symptoms, ask your eye doctor about artificial tears for use during the day. By the way, don't confuse lubricating eye drops with the drops formulated to . But they are not necessarily formulated to reduce dryness and irritation. To reduce your risk of dry eyes during computer use, try this exercise: Every 2. This will help rewet your eyes. To ease eye strain, make sure you use good lighting and sit at a proper distance from the computer screen. Exercise your eyes. Another cause of computer eye strain is focusing fatigue. To reduce your risk of tiring your eyes by constantly focusing on your screen, look away from your computer at least every 2. Some eye doctors call this the . Then look back at the distant object. Do this 1. 0 times. This exercise reduces the risk of your eyes' focusing ability to . Also, remember to blink frequently during the exercises to reduce your risk of computer- related dry eye. Take frequent breaks. To reduce your risk for computer vision syndrome and neck, back and shoulder pain, take frequent breaks during your computer work day. Many workers take only two 1. According to a recent NIOSH study, discomfort and eye strain were significantly reduced when computer workers took four additional five- minute . Data entry speed was significantly faster as a result of the extra breaks, so work output was maintained even though the workers had 2. During your computer breaks, stand up, move about and stretch your arms, legs, back, neck and shoulders to reduce tension and muscle fatigue. Check your local bookstore or consult your fitness club for suggestions on developing a quick sequence of exercises you can perform during your breaks and after work to reduce tension in your arms, neck, shoulders and back. Modify your workstation. If you need to look back and forth between a printed page and your computer screen, this can cause eye strain. Place written pages on a copy stand adjacent to the monitor. Light the copy stand properly. You may want to use a desk lamp, but make sure it doesn't shine into your eyes or onto your computer screen. Improper posture during computer work also contributes to computer vision syndrome. Adjust your workstation and chair to the correct height. Purchase ergonomic furniture to enable you to position your computer screen 2. The center of your screen should be about 1. Consider computer eyewear. For the greatest comfort at your computer, you might benefit from having your eye care professional modify your eyeglasses prescription to create customized computer glasses. This is especially true if you normally wear contact lenses, which may become dry and uncomfortable during sustained computer work. Computer glasses also are a good choice if you wear bifocals or progressive lenses, because these lenses generally are not optimal for the distance to your computer screen. Back to top .

How to Fix Computer Problems? Problems with computer are divided into two groups, i. The hardware problems are related to the peripheral parts of the computer like the CD drive, hard disk, monitor, keyboard, etc. The software problems are more complicated. These problems include problems like modem problems, Windows not starting, drivers not found, etc. Understand what is causing the glitch and follow the standard procedure to solve the problem. The following are a few common problems and solutions to help you overcome the technical snag. After Power Outage. Today there are many sudden power outages, voltage problems and spikes that can damage computers. These damages cause many technical and software snags and interrupt your work. This leads to loss of data, damage to the hardware, etc. This is a solution to this trouble is use of uninterrupted power supply (UPS). The UPS can provide a constant flow of energy to the computer, even if you encounter a sudden power outage. This will provide you with ample time to save your data and shut down your PC, if needed. Computer Performance has Slowed Down. You may notice your computer has slowed down considerably and even a simple command execution takes ages. This is because your computer is loaded with unnecessary files, fragmented data, corrupted registry, spyware programs, services, software, etc. Thus, you need to manage your programs and delete unnecessary data and software that you do not use or need, clean your registry regularly to help boost at least 3. No Sound from Speakers. You are in the mood to listen to some groovy music on your PC, but you get no sound from speakers, the solution to is to check the back of the computer and see if all the connectors are properly connected. The speaker or single stereo speaker plug should be put into the socket on the soundcard that has a mark Audio Out. Computer Monitor Displays Fuzzy Images. A computer monitor is the display unit of the computer that is sensitive to electro- magnetic radiations. These electro- magnetic radiations are transmitted from the TV, radio, microwaves, dishwashers, washing machines, speakers, etc. Mobile phones transmit electro- magnetic radiations that is one of the main cause of monitor displaying fuzzy images. Thus, move away these disturbances away from the monitor and this problem with computer monitor will be fixed. Computer Freezes with Blue Screen Hijacking Your Display. There are many problems that can cause your computer screen to freeze and blue screen to appear. This screen is called the Blue Screen of Death (BSOD). This may be due to a spyware or computer viruses that have affected your computer. You need to update your anti- spyware and scan your computer for any viruses. If your computer is free from any such malicious software, then you may need to update your hardware drive. A hardware drive that is not updated may cause the CPU to lock up and interrupt working of the computer. If you find the problem cropping up even after a hardware drive update, then you may need to increase computer RAM. When you increase the RAM, the computing power increases and you will also be able to avoid the computer freeze. At times, BSOD may appear due to critical errors in the driver, software or registry problems. Windows may have to repair or reinstall missing components. If you do not find any visible cause, it would be wise to call the computer technician. Computer Reboots Itself Again and Again. Another common problem with computers. In order to fix the problem of rebooting itself again and again, you will need to check the hardware. You may have a faulty power supply, defective or dirty cooling fan, etc., that may cause the computer to reboot again and again. The dust that accumulates on the fan, makes it heat up faster and in order to cool down the computer automatically switches off. Thus, clean the fan and check for power supply. Following these simple steps will help you to solve these problems with computer. Computer Makes Strange Noises. Noises and vibrations from your computer are a hardware problem. Many electronic parts can make high pitch noises. You need to switch off your computer and unplug it from the power supply. Now remove the case from the CPU and restart your computer. Locate the origin of noise and then switch off the computer and unplug it. It may be a faulty fan, loose wire or screw.

You may have come across the message 'Windows Shutting Down' instead of 'It is now safe to switch off you computer'. This is because a program has not unloaded itself properly that makes the computer insist to run a scandisk the next time you switch on. You need to close all the programs before your shut down your PC and if it is not done, the computer waits for the program to close. It may happen you get the message 'Do you want to shut this program down or wait' or you may not. When you don't get such a message it results in what we call the hanging of the operating system. The solution is not to install Direct X whenever you install a game. Most games have their version of Direct X that makes the files out of sync.
