People who affirm that whatever has an advantage also has a disadvantage are ready to point at the recent developments of Computer Vision Syndrome. The disorder is a side effect of staying too long on the computer. Computer Vision Syndrome acts as a hindrance to advancements in technology as it discourages people from working with the computer.
About Computer Vision Syndrome
We use computers on daily basis. Apart from its usefulness during leisure hours, it is also a vital tool in most professions. According to research, about 60% of jobs in the world cannot be done without the computer. Unfortunately, when a person uses the computer for several hours, computer vision syndrome can result. This can simply be described as a temporary eye defect that prevents normal vision and creates discomfort to the sufferer.
It is possible to find this in all geographical regions. According to the National Institute of Occupational Health and Safety, about 90% of people who use the computer for at least three hours each day have the syndrome. During a study conducted among Malaysia college students from the ages of 18 to 25, it was discovered that those who suffered from the syndrome were approximately 90 percent.
How Can You Identify Computer Vision Syndrome
Some of the symptoms of CVS include back pain, neck pain, eye pain, double vision and blurry vision. There has been no case to suggest that CVS can lead to a permanent eye condition. However, this eye defect reduces the efficiency of the sufferer at work.
What’s The Cause of CVS?
The main cause of the syndrome is prolonged exposure to the rays from the computer screen. The eye experiences more strain when viewing the computer than it does when reading a book. This is because the ciliary muscles do more work to bring rays from the object on the retina.
It is easier to develop this syndrome if the person already has some eye defects. Some examples of computer related eye problems include astigmatism and shortsightedness. Unfortunately, people above the age of 40 will find it difficult to work for long hours on the computer because at this age, the lens is weak and unable to properly bend the light rays from the object onto the retina. This is why accommodation of very close object is difficult. Vision problems experienced at old age is caused by presbyopia.
There are other factors that can increase the risk of having computer vision syndrome. These factors include: working in a room with few bulbs, neglecting good sitting posture before your computer screen and increasing the brightness of the screen to unsafe levels.
Curative Measures for Computer Vision Syndrome
There are so many cures for this syndrome. The first thing you should do if you suspect CVS is to visit an eye doctor. You may be asked to purchase a recommended lens. This lens is different from the general sun glasses so you shouldn’t neglect the advice if it comes from the doctor. Other things you can do to cure or prevent CVS include increasing the number of bulbs in the room and sitting properly before the monitor. The use of anti-glare screens is also helpful.
How to Prevent Computer Vision Syndrome
The fear of having CVS should not make you quit your job. Instead, you should take pragmatic approach to prevent it. For example, you can take breaks when working or divide your work into tiny bits. It is recommended that you take a break of 15 minutes if you intend to work for two hours. Also take away your gaze on the computer screen every 20 seconds after every 20 minutes.
Don’t forget to blink frequently while sitting before the computer. Blinking is an act that helps to moisten the eyes and thus reduces the strain on the lens and ciliary muscles. People with dry eyes can alleviate their problem by using lubricating eye drops.
You can also decide to change your computer settings. It is unreasonable to continue working with the default settings if they are making you uneasy. Among other things, you should change the font size, brightness and contrast of the computer. Doing this can help you prevent having computer vision syndrome.
Finally, do not neglect the practice of going to see a doctor regularly. You must not wait for those symptoms to occur before going to see the eye doctor. Prompt and regular examination of your eyes will make it healthier even in your old age. On the other hand, less frequent visits will increase your chances of having computer vision syndrome. Moreover, waiting until you experience symptoms can lead to more expenses and the time to recover from the condition may be prolonged.
