What You Need to Know About Computer Vision Syndrome

Computer vision syndrome (CVS) or digital eye strain is a condition which is related to the amount of time we spend in front of the screens of various modern devices. As technology progresses and we find ourselves  either working or relaxing in front of one such device, we put more strain on our eyes and this is why we will take a look at these conditions and what you need to prevent it.


What is CVS?

The prolonged exposure to the blue light from devices such as tablets, phones, TVs and other similar devices and the constant struggle to focus on them, can cause a wide range of issues for you and your vision.

Technology is a major time saver and a great entertainer, so it's easy to get lost in the loop and not realise that exposing yourself too much to it can have a negative effect as well.

While this condition is not permanent, timely treatments can make your life much easier. Having to work with digital eye strain can be very unproductive due to the number of irritations it might cause you. There is also that chance that a prolonged period of time without any treatment, can open up the door to some other condition to progress too.

Even when it is not work related, stepping away from the screen can be a challenge and appropriate measures need to be taken if you find yourself in a similar situation.


What are the symptoms of CVS?

There are a number of symptoms, that can be experienced by the people suffering from this condition, among which are:

- headaches

- dry eyes

- double or blurred vision

- while indirect, poor posture can hurt your neck and shoulders

- itchiness and burning are too other common sensations resulting from it

- sleep disturbances

- redness

The more you are exposed and avoid taking measures, the more severe and harder to go away the symptoms will be.


What causes CVS?

Whether you get CVS and how quickly it will go away depends on your lifestyle. The most common contributors for it are long hours in front of the screen. Whether you need to work or surf for information and entertainment, 4+ hours in front of the screen can easily set the stones for a CVS.

Bad positioning and posture can contribute a lot as well. Having your face in the screen, while sitting too close to it will surely do your eyes some harm.

Poor light can be another contributor for this condition setting in faster.


How do you treat CVS?

The best thing you can do for yourself and your eyes if you suspect you might have CVS, is to take some time off the screen. Now unfortunately this is not always possible, especially when this is the primary way you put food on your table, so you will need a way to:

- Take breaks as often as possible

- Assume a good position and work with appropriate font

- Buy devices with screens that are kinder to the eye

Visiting your eye specialist can greatly help as well. Among the things they can prescribe to you are :

1. Eye drops - In some cases individuals are unable to produce enough tears to keep their eye moist, which can lead to a number of irritations such as itchiness, redness and burning sensation, which can be a big annoyance especially if you need to concentrate.

2. Glasses and lenses - even if you normally do not require glasses or lenses, they can save you a world of pain if you have them when working in front of the computer. Sometimes this condition can also lead to temporary nearsightedness or farsightedness, but they can reduce the amount of blue light plaguing your eyes.


It is important to give this condition the needed attention in order to make your life much easier. If you need or want to spend long hours in front of a computer, you should consider any symptoms and get them treated, because while not this dangerous, this condition can still impact your daily life and productivity.
