Do you experience eyestrain, headaches, backaches, and blurry vision after working on your computer the whole day? Do your eyes even feel like twitching at times? If yes, then you are experiencing computer vision syndrome (CVS).
Millions of people in the US alone are suffering from the symptoms of CVS. As the use of computers and other digital devices has already become a necessity, the symptoms of the condition are experienced by many—regardless of age. People may not know the medical term, but CVS is very real to them.
Development of CVS
Basically, CVS develops because the brain and the eyes are reacting differently to the characters or images on the computer screen. They differ from printed characters on paper as they are not as dense and as black.
Unlike printed letters, characters on the computer screen are formed by pixels. Pixels are tiny points of light which are brightest at the center. As the points move away from the center, the brightness becomes less, making it harder for the eyes to focus on the images. For the eyes to read the characters well, continuous flexing of the muscles is necessary. Apparently, this results in computer vision syndrome.
Prevention of CVS
There are some ways to prevent the development of CVS. Of course, the most sensible thing to do would be to consult a doctor who specializes in computer vision care. He or she would be able to perform necessary tests to know what you have and how to solve your problem.
It would be very likely the doctor would prescribe a pair of computer glasses to alleviate CVS symptoms. These glasses would enable you to work on the computer a lot more comfortably. Don’t worry; these glasses look the same as your conventional eyeglasses. They only differ in the lenses.
Aside from wearing computer glasses, there are practical things that you can do to reduce your risk of CVS. For one, you can improve the setup of your workstation. Here are some useful tips on how to do just that:
*Place the monitor right in front of you, not on the side.
*Set it so the center of the screen would be just a few inches below your straight gaze.
*While working, you should keep your back and shoulders straight. Your arms must be parallel to the floor, and your feet must be flat on it.
Aside from improving your workstation, improving your work habits can reduce CVS too. For example, instead of staring at the monitor continuously for hours, you should take a break every fifteen minutes or so. Look somewhere far and focus your eyes on an object. This will give your eyes some time to rest.
These are some of the things that can help you steer clear from computer vision syndrome. Remember that the more you protect yourself from CVS, the more productive you can be. After all, muscle fatigue, in whatever part of the body, can significantly lessen one’s competence and productivity. If you take care of your eyes, you can get more job done well.
Seven Fantastic Ways to Prevent Computer Eye Strain
Computer eye strain is prevalent among people who use the computer for more than two hours every day. It is a common symptom of Computer Vision Syndrome (CVS)—a growing condition which is a byproduct of the use of modern technology.
Aside from computers, eye strain can develop by using other hand-held devices such as iPod, PSP, iPhones, and the likes for long hours each day. Luckily, there are some things you can do to lessen or relieve the symptoms. In this article, you will learn about seven fantastic ways on how to prevent computer eye strain
1. Check computer screen location
Ideally, the computer screen must be between 20 and 28 inches from you and 15 to 20 degrees below eye level as measured from its center. This will make viewing a lot more comfortable.
2. Ensure proper lighting
You should never take good lighting for granted. Poor illumination can easily strain the eyes. When working, ensure that bright lighting overhead is at its minimum. If you are using a desk lamp, it should be shining on your desk and not at you.
3. Reduce glare
Scrutinize your workspace and check for any sources of glare. The monitor can act as a mirror which reflects light sources and shiny objects. To prevent this from happening, you can use some curtains or blinds. You may also reposition your screen. Put it in an angle that will lessen reflections. Don’t forget also to adjust the brightness and contrast of your monitor display. Remember that the more you reduce glare, the more you prevent yourself from eye strain.
4. Increase font size
Dealing with tiny and blurry characters on the computer for hours can make you squint. Aside from tiring the eyes, it makes you lean back and forward too. This can be avoided by increasing the size of your font. By doing so, the words will become a lot easier to read. The point size should be big enough so that you can comfortably sit back in your chair and read.
5. Practice the 20/20/20 rule
Whenever you spend long hours using a digital device, remember to pause every 20 minutes. For 20 seconds, look at something 20 feet away. This will allow your eyes to rest and relax. Such a cool rule, don’t you think?
6. Use computer glasses
You may want to consult an optometrist and ask about computer glasses. These glasses are specially made for computer use so symptoms of CVS can be relieved. Even if you are already wearing a pair of non prescription reading glasses, using computer reading glasses is highly needed when working on the device.
7. Blink often
When using a computer or any other hand-held device, it is common for you to blink two or three times less than normal. As a result, your eyes become dry and irritated. By blinking, you moisten your eyes enough. Tears can easily give your eyes natural therapy.
These are the best ways to relieve and prevent computer eye strain. Practice them, and you will surely be able to work on your computer a lot more comfortably.
