In today business world, working in an office involves the use of computers, tablets, and other mobile gadgets. With so many people using computer systems to facilitate official tasks, one common issue that is rampant among office workers is eye strain.
According to the recent studies, eye strain, as well as other worrisome visual symptoms, ensues in about 90% of users of computers.
Other problems associated eye problems are physical fatigue which leads to increased work errors and decreased productivity, red eyes, and eye twitching.
But what could be the cause of eye strain? A human being blinks about 15 times in one minute, evenly spreading tears over the eyes. This prevents the eyes from becoming irritated and dry. But research has shown that people who regularly stare at computer screens hardly blink; they blink less than half as often when watching, playing, or reading on a screen.
Additionally, the contrast or dissimilarity of text against the background as well as the flickering and the glare that is a common phenomenon of digital displays can be very hard on the human eye.
So, what are the preventive measures to put in place to prevent eye problems? Is it necessary to cut out the time spent on computer screens?
Well, if you can cut out screen time and it will not affect your work, by all means, do so. But that option is next to impossible, given the widespread use of smartphones which are rapidly replacing computer screens.
Therefore, here are some tips you should follow that will help you in preventing eye problems from computer screens.
Always position the computer screen about 25 inches away from your face. Ensure that the center of the screen is about 10 to 15 degrees below the level of your eyes.
Adopt the 20-20 rule: after every twenty minutes of staring at a computer screen, look away from the screen to gaze at objects that are about twenty feet away for a minimum of twenty seconds.
Reduce the illumination or screen resolution. If the resolution is still too bright, get a matte or nonglossy screen filter that will help in reducing the illumination drastically. They are available for computers, tablets, and phones.
Refresh your eyes with artificial tears if you feel them running dry.
In case you use contact lenses, you should give your eyes a little break by making use of your glasses.
After every two hours spent on your devices – computers, tablets, smartphones, etc. – take a long break of about fifteen minutes.
Make sure you go for eye checkups or exams regularly. If there is a need for you to use a different pair of eyeglasses when working on your computer – especially the tinted type – then use them.
Increase the refresh rate of your devices to minimize the flickering of the screen.
Blue light is associated with eye strain. Therefore, reduce the color temperature of the screens of your devices, and this will give off less blue light.
Consider changing the monitors of your computer to a liquid-crystal display (LCD) since they come with embedded anti-reflective surfaces as well as higher refresh rate.
Drink lots of water so that you can stay hydrated. Dehydration worsens dry eyes and makes them more irritable.
