Combating Digital Eye Strain
We are in the era of computers, smart phones, computer, tablet and other devices with visual displays. What they all have in common is that they all can cause tired eyes, digital eyes strain and computer vision syndrome.
The most alarming thing right now, according to a recent eyes survey in 2015, is that it has been proven that more computer eyes related problems are on the rise. Well, this happens because, many young people now spend more and more time using the computer either as a form of entertainment or for school work. Studies show that eyes strain and other bothersome visual symptoms occur among 50 to 90 percent of computer workers.
These problems can range from physicals fatigue, decreased productivity, repeating work errors, to minor annoyances like eyes twitching and red eyes.
If you are caught up in the storm of digital eyes strain, here are ways to combat it.
Symptoms of Computer Vision Syndrome
If you or your children spend more than two hours in front of the computer every day, it’s likely you will experience certain degrees of computer vision syndrome, these include: headaches, loss of focus, burning eyes, tired eyes, red eyes, double visions, shoulder and neck pain.
Causes of Computer Vision Syndrome
According to Tunde Babalola, an optician, the reason we tend to suffer from eyes strain and computer vision syndrome are because our eyes and brain react differently to the character on the screen. You see, the eyes and the brain react in a better way to a printed character and they have no problems focusing on these printed materials. Unlike the printed materials that have dense black characters with well defined edges, computer screen does not have the same contrast and definition.
What to do?
Comprehensive eyes test
Babalola suggest that the best way to deal with this is to do regular comprehensive eyes test. In his word, “having a routine comprehensive eyes exam is the most important thing you can do to prevent or treat computer vision problems. during the test, make sure you explain to your doctor, your eye doctors will want to know how you sit with your lap top so that he can measure from distance too”
According to the National Institute of Occupational Safety and Health (NIOSH), computer users should undergo eyes examination before they start working on a computer and once a year thereafter.
When you use a computer, your ambient lighting should be about half as bright as that, typically found in most offices. The doctors, also suggest that exterior light should not be shot out by closing the drapes, window and shades. If possible position your computer monitors or screen so that the window are the side, instead of in front or behind it.
Minimize you glare
Staring at the computer for too long can cause a strain on your sight. If you can, install anti glare screen on your monitor and, if possible, paint bright white walls a darker color with matte finish. If you are already wearing glasses, request for lenses with anti reflective coating, this reduce glare by minimizing the amount of light reflecting off the front and back surface of your eyeglass lenses.
Upgrade your displays
Thank God the old tube like computer are gradually fading off. But if you are still stucked with one, it’s high time you make a change. LCD screen are easier on the eyes and usually have anti reflective surface. Old fashioned CRT screens cause a noticeable “flickers” of images, which is a major cause of computer eyes strain.
Adjust the display settings
If you are getting so uncomfortable with your displays setting, change it and make you eyes loss strained. Adjust the brightness, the text size and contrast, and the color temperature too.
Blink more often
Blinking is very important when working at a computer; blinking moisten 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. Meanwhile, more blinks performed during computer works are only partial lid closures, according to studies.
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 20 minutes and gaze at a distant object (at least 20 feat away) for at least 20 seconds.
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.
