In the field of competition, we are using many electronic gadgets for work easily. The computer is one of them; eye strain has become a complaint related to the main job. Studies show that eye strain and other annoying visual symptoms occur in 50 – 90% of computer operators.
These problems can range from physical weakness, reduced productivity and the increased work errors to difficulties such as eye contractions and red eyes.
Here are 5 easy ways you can take to reduce your risk of computer eye strain and other common symptoms of computer vision syndrome.
Get a Comprehensive Eye Examination –
Having a full routine comprehensive eye examination is the most important thing you can do to prevent or treat computer vision problem. If you have not had eye checkup more than one year, schedule a visit best eye hospital in india.
According to the NIOSH (National Health and Safety Institute), the computer users should have an eye examination before they start to work on computer and once a year thereafter.
During your examination, be sure to tell your eye specialist doctors how often you use a computer at work. Measure how your eyes are on your screen when you sit at computer, and make this dimension for your examination so that your eye doctor can test your eyes at that distance of specific work.
Use Proper Lighting –
Eye strain is often caused by excessively bright lighting from the outdoor sunlight coming through a window or a harsh indoor lighting. When using any electronic gadgets (like mobile, computer, T.V etc.) your ambient lighting should be about half as bright as that normally found in mainly 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.
Reduce external light by closing shades, drapes, or blinds. Reduce indoor lighting by using fewer fluorescent bulbs or tubes or use light bulbs and tubes of low intensity. If possible, place your computer screen or sort of screen windows are to the side, instead of in front or behind.
Most of the computer user found their eyes feels better if they can avoid working under fluorescent lamp overhead. If possible, turn off the overhead fluorescent light in your office and use of floor lamp that provide indirect incandescent or halogen lightings instead.
Sometimes, switching to “spectrum” fluorescent lightings that are closer to the spectrum of light emitted by the sun can be more comfort for computer workers than ordinary fluorescent tube. Even full spectrum lighting can cause discomfort if it is too bright. Try reducing the number of fluorescent tubes installed above your workspace from the computer if you are bothered by overhead lighting.
Minimize Glare –
Glare on walls and finished surfaces, as well as reflections on your computer screen can also cause computer eye stress. Consider installing anti-glare screen on your monitor and, if possible, paint bright white wall a darker color with a matte finish.
Again cover all the windows. When the outsider light can't be reduced, using a computer screen cover.
If you wear glasses, buy lenses with AR (anti-reflective) coating. Anti-reflective coating reduces glare by minimizing the light reflected from the front and back surfaces of your lenses.
Upgrade Your Display –
If you haven't done so, replace your old tube style monitor with a flat – panel LCD (Liquid Crystal Display), like those on computers laptop.
LCD screens are easier on eyes and usually have anti-reflective surfaces. Old – fashioned CRT (Cathode Ray Tube) screens can cause a visible “flickers” of images, which is a major cause of computer eyes strain. Even if these flickers are invisible, it still can contribute to eyes strain and stress during computer works.
Complications due to flicker are even more likely if the monitor refresh rate is less than 75 Hz. If you must use a CRT (Cathode Ray Tube) at works, adjust the display setting to the highest possible refresh rate.
When choosing a new flat screen, select a screen with the highest resolution possible. The resolution is related to the “dot pitch” of the screen. Generally, the screens with no lower point have sharper images. Choose the screen with a dot pitch of 0.28 mm or lesser.
Flicker is not an issue with LCD (Liquid Crystal Displays) screen, as the brightness of the pixels on the screen is controlled by a “backlight” which generally operates at 200 Hz.
If you see a lower refresh rate (for example 60 Hz) indicated on an LCD screen, don't worry – this refer to the frequency of a new image is received from the video cards, not how many time the brightness of screen pixel is updated, and the functions are usually not associated with eye strain.
Lastly, choose the relatively large displays. For a laptop or desktop, select the display that has a diagonal screen size of at least 19 inches.
Adjust Your Computer Display Settings.
Adjust the computer display setting can help reduce eye strain and stress. In general, these adjustments are beneficial for us –
Brightness – Adjust the brightness of screen so that it is roughly the same as the brightness of the surrounding workplace. As a test, look at the white background of this web page. If it looks like a light source, it is too bright. If it looks gray and dull, it may be too dark.
Text Size and Contrast – Adjust the contrast and text size for comfort, especially when reading or composing long contents. Usually, print on white background is best combination for comfort.
Color temperature – This is a technical term used to describe the visible light spectrum emitted by a color screen. The blue light is of shorter wavelength of visible light which is associated with more than eye strain that over wavelength colors, such as orange and red. Color temperature reduction of your screen reduces the amount of blue light emitted by a color screen for better comfort of long term vision.
Computer glasses also are a good choice if you wear progressive lenses, but regular eye checkup is very important.
