Reducing the color temperature of your display lowers the amount of blue light emitted by a color display for better long-term viewing comfort. Blue light is short-wavelength visible light that is associated with more eye strain than longer wavelength hues, such as orange and red. Usually, black print on a white background is the best combination for comfort.Ĭolor temperature: This is a technical term used to describe the spectrum of visible light emitted by a color display. Text size and contrast: Adjust the text size and contrast for comfort, especially when reading or composing long documents. If it seems dull and gray, it may be too dark. If it looks like a light source, it's too bright. As a test, look at the white background of this Web page. Generally, these adjustments are beneficial:īrightness: Adjust the brightness of the display so it's approximately the same as the brightness of your surrounding workstation. Adjust your computer display settings.Īdjusting the display settings of your computer can help reduce eye strain and fatigue. For a desktop computer, select a display that has a diagonal screen size of at least 19 inches. 28 mm or smaller.Īlso, choose a relatively large display. Generally, displays with a lower dot pitch have sharper images. Resolution is related to the 'dot pitch' of the display. When choosing a new flat panel display, select a screen with the highest resolution possible. If you must use a CRT at work, adjust the display settings to the highest possible refresh rate. To ease eye strain, make sure you use good lighting and sit at a proper distance from the computer screen.Ĭomplications due to flicker are even more likely if the refresh rate of the monitor is less than 75 hertz (Hz). Even if this flicker is imperceptible, it still can contribute to eye strain and fatigue during computer work. Old-fashioned CRT screens can cause a noticeable 'flicker' of images, which is a major cause of computer eye strain. If you have not already done so, replace your old tube-style monitor (called a cathode ray tube or CRT) with a flat-panel LED (light-emitting diode) screen with an anti-reflective surface. AR coating reduces glare by minimizing the amount of light reflecting off the front and back surfaces of your eyeglass lenses. If you wear glasses, consider buying lenses with anti-reflective (AR) coating. Consider installing an anti-glare screen on your display and, if possible, paint bright white walls a darker color with a matte finish. Screen also can cause computer eye strain. Glare from light reflecting off walls and finished surfaces, as well as reflections on your computer Try reducing the number of fluorescent tubes installed above your computer workspace if you are bothered by overhead lighting.

But even full spectrum lighting can cause discomfort if it's too bright. Sometimes switching to 'full spectrum' fluorescent lighting that more closely approximates the light spectrum emitted by sunlight can be more comforting for computer work than regular fluorescent tubes. If possible, turn off the overhead fluorescent lights in your office and use floor lamps that provide indirect 'soft white' LED lighting instead. Many computer users find their eyes feel better if they can avoid working under overhead fluorescent lights.

Reduce interior lighting by using fewer light bulbs or fluorescent tubes, or use lower intensity bulbs and tubes.Īlso, if possible, position your computer screen so windows are to the side, instead of in front or behind it. When you use a computer, your ambient lighting should be about half as bright as that typically found in most offices.Įliminate exterior light by closing drapes, shades or blinds. Use proper lighting.Įye strain often is caused by excessively bright light either from outdoor sunlight coming in through a window or from harsh interior lighting.

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. During your exam, be sure to tell your eye doctor how often you use a computer and digital devices at work and at home. Get a comprehensive eye exam.Īn annual comprehensive eye exam is the most important thing you can do to prevent or treat computer vision problems. Here are 10 easy steps you can take to reduce your risk of eye strain and the symptoms that go along with it: 1. Research sponsored by The Vision Council showed that 59% of people who routinely use computers and digital devices experience symptoms of digital eye strain (also known as computer eye strain or computer vision syndrome). It's causing a widespread problem called digital eye strain. It seems like everyone is staring at a computer screen, phone or other digital device these days.
