How to Relieve Computer Eye Strain

If you are experiencing eye strain from working at the computer, then you should try our 10 steps on how to relieve this eye strain.

With a lot of us using computers at work, computer eye strain has become a significant job-related complaint. Studies show that eye strain and other bothersome visual symptoms occur in 50 to 90 percent of computer workers.

These problems can range from physical tiredness, decreased efficiency and increased numbers of work errors, to small inconveniences like eye twitching and red eyes.

Here are 10 easy steps you can require to decrease your risk of computer eye strain and other typical symptoms of computer vision syndrome (CVS):

1. Get a thorough eye exam

Having a routine thorough eye examination is the most essential thing you can do to avoid or treat computer vision issues. If you have not had an eye test in over a year, schedule a check out with an optometrist near you.

Inning accordance with the National Institute of Occupational Safety and Health (NIOSH), computer users ought to have an eye test before they begin working on a computer and as soon as a year thereafter.

During your exam, be sure to inform your eye doctor how typically 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 particular working range.

2. Use proper lighting

Eye strain often is caused by exceedingly intense light either from outside sunlight being available in through a window or from harsh interior lighting. When you use a computer, your ambient lighting ought to be about half as intense as that typically discovered in many offices.

Eliminate exterior light by closing drapes, shades or blinds. Reduce interior lighting by utilizing less light bulbs or fluorescent tubes, or use lower strength bulbs and tubes. If possible, place your computer screen or screen so windows are to the side, instead of in front or behind it.

Numerous computer users discover their eyes feel better if they can avoid working under overhead fluorescent lights. If possible, switch off the overhead fluorescent lights in your office and use floor lamps that offer indirect incandescent or halogen lighting rather.

In some cases changing to “full spectrum” fluorescent lighting that more carefully estimates the light spectrum released by sunshine can be more comforting for computer work than regular fluorescent tubes. But even full spectrum lighting can cause pain if it’s too bright. Attempt minimizing the number of fluorescent tubes set up above your computer work space if you are bothered by overhead lighting.

3. Reduce glare

Glare on walls and ended up surface areas, along with reflections on your computer screen likewise can cause computer eye strain. Consider installing an anti-glare screen on your screen and, if possible, paint intense white walls a darker color with a matte surface.

Once again, cover the windows. When outdoors light can not be reduced, consider utilizing a computer hood.

If you wear glasses, purchase lenses with anti-reflective (AR) coating. AR coating lowers glare by reducing the quantity of light reflecting off the front and back surface areas of your spectacles lenses.

4. Upgrade your display

If you have actually not currently done so, replace your old tube-style screen (called a cathode ray tube or CRT) with a flat-panel liquid crystal display (LCD), like those on laptop computers.

LCD screens are simpler on the eyes and generally have an anti-reflective surface. Old-fashioned CRT screens can cause a noticeable “flicker” of images, which is a significant cause of computer eye strain. Even if this flicker is invisible, it still can contribute to eye strain and tiredness during computer work.

Complications due to flicker are a lot more most likely if the refresh rate of the screen is less than 75 hertz (Hz). If you should use a CRT at work, adjust the display settings to the highest possible refresh rate.

When selecting a brand-new flat panel display screen, choose a screen with the greatest resolution possible. Resolution is connected to the “dot pitch” of the display screen. Typically, shows with a lower dot pitch have sharper images. Pick a display screen with a dot pitch of.28 mm or smaller.

Flicker is not an issue with LCD screens, because the brightness of pixels on the display are controlled by a “backlight” that usually runs at 200 Hz.

If you see a lower refresh rate (e.g. 60 Hz) kept in mind on an LCD screen, do not fret– this describes how often a brand-new image is gotten from the video card, not how often the pixel brightness of the screen is updated, and this function typically is not connected with eye strain.

Lastly, pick a fairly big display. For a desktop computer, pick a display that has a diagonal screen size of at least 19 inches.

Try utilizing eye drops or synthetic tears if you discover your eyes become dry from excessive screen time. If you do take place to use restorative lenses or contacts, make certain to keep your prescription existing with regular eye tests. If you find yourself with regular eye fatigue and you’ve eliminated other possible causes, the issue could lie with your vision itself, and you should make a visit with a healthcare specialist.

5. Change your computer screen settings

Changing the display settings of your computer can help in reducing eye strain and fatigue. Typically, these changes are helpful:

Brightness. Adjust the brightness of the screen so it’s around the same as the brightness of your surrounding workstation. As a test, look at the white background of this Websites. If it appears like a light, it’s too bright. If it appears dull and gray, it might be too dark.

Text size and contrast. Adjust the text size and contrast for convenience, particularly when reading or making up long files. Generally, black print on a white background is the best mix for comfort.
Color temperature level. This is a technical term used to explain the spectrum of visible light given off 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. Lowering the color temperature of your display decreases the quantity of blue light emitted by a color display for much better long-lasting watching comfort.

For computers operating on a Microsoft Windows operating system, display settings can be adjusted in Control Panel. For an Apple computer, display settings are discovered in Systems Preferences (in the Applications folder in Finder).

In some cases, the color temperature of a home computer monitor is changed on the display screen itself.

6. Blink regularly

Blinking is very important when operating at a computer; blinking moistens your eyes to prevent dryness and inflammation.

When operating at a computer, individuals blink less frequently — about one-third as frequently as they generally do– and many blinks performed during computer work are only partial lid closures, according to research studies.

Tears coating the eye evaporate more rapidly during long non-blinking phases and this can cause dry eyes. Also, the air in many workplace environments is dry, which can increase how quickly your tears vaporize, positioning you at greater risk for dry eye issues.

If you experience dry eye symptoms, ask your eye doctor about synthetic tears for use during the day.

By the method, do not puzzle lubricating eye drops with the drops created to “get the red out.” The latter can certainly make your eyes look better– they contain ingredients that decrease the size of capillary on the surface area of your eyes to “bleach” them. However they are not always created to reduce dryness and inflammation.

To minimize your risk of dry eyes during computer use, attempt this exercise: Every 20 minutes, blink 10 times by closing your eyes as if going to sleep (really gradually). This will help rewet your eyes.

7. Exercise your eyes

Another reason for computer eye strain is focusing fatigue. To decrease your risk of tiring your eyes by constantly concentrating on your screen, look away from your computer at least every 20 minutes and look at a distant item (at least 20 feet away) for at least 20 seconds. Some optometrist call this the “20-20-20 guideline.” Looking far away relaxes the focusing muscle inside the eye to lower tiredness.

Another exercise is to look far away at an object for 10-15 seconds, then look at something up close for 10-15 seconds. Then recall at the distant things. Do this 10 times.

This workout lowers the risk of your eyes’ focusing capability to “secure” (a condition called accommodative convulsion) after prolonged computer work.

Both of these exercises will reduce your risk of computer eye strain. Likewise, remember to blink regularly during the exercises to reduce your risk of computer-related dry eye.

8. 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.

Numerous workers take only two 15-minute breaks from their computer throughout their work day. According to a recent NIOSH research study, discomfort and eye strain were significantly lowered when computer workers took 4 additional five-minute “mini-breaks” throughout their work day.

And these supplementary breaks did not decrease the workers’ performance. Data entry speed was considerably much faster as an outcome of the additional breaks, so work output was maintained although the employees had 20 extra minutes of break time every day.

During your computer breaks, stand, move about and extend your arms, legs, back, neck and shoulders to minimize stress and muscle fatigue.

Check your local bookstore or consult your fitness club for recommendations on establishing a quick sequence of exercises you can perform during your breaks and after work to lower tension in your arms, neck, shoulders and back.

9. Modify your workplace

If you need to recall and forth between a printed page and your computer screen, this can cause eye strain. Place composed pages on a copy stand nearby to the display.

Proper workplace to avoid a computer eye strain

Light the copy stand properly. You may want to use a desk light, however ensure it doesn’t shine into your eyes or onto your computer screen.

Improper posture during computer work also contributes to computer vision syndrome. Change your workstation and chair to the right height.

Purchase ergonomic furnishings to enable you to place your computer screen 20 to 24 inches from your eyes. The center of your screen should have to do with 10 to 15 degrees listed below your eyes for comfortable positioning of your head and neck.

10. Think about computer eyeglasses

For the best convenience at your computer, you may take advantage of having your eye care expert modify your spectacles prescription to create tailored computer glasses. This is particularly true if you usually wear contact lenses, which might end up being dry and unpleasant during continual computer work.

Computer glasses also are a great option if you wear bifocals or progressive lenses, since these lenses typically are not optimal for the distance to your computer screen.
