Have you experienced a time wherein your eyes become sore after using your computer? Or is there a moment that your eyes become red and irritated? Well, you may be suffering from Computer Vision Syndrome.

What is Computer Vision Syndrome (CVS)?

Computer Vision Syndrome is the term used for all the vision and eye-related problems caused by digital screens. Basically, if you use computer, cell phone, laptop, tablet or even television and you experience problem in your eyes then you may have CVS.

These problems usually happen when you stare at the computer screen for long period of time without taking any break.

We all know that we are already in the electronic age, and these devices are already part of our daily routine.  But people usually ignore the problem with their vision.

According to researchers, about 40% to 85% of the people who work on computers all day long show major symptoms of the syndrome. And the number of people continues to rise throughout the years.


What happens inside your eyes?

You may be thinking, what really happens inside your eyes? Let me explain it as simple as possible.

Let’s consider a case when you are browsing the internet on your computer. When you look at the images and text on the screen, our eyes continuously focuses and refocuses which exerts a considerable amount of strain on the eye muscles.

Now multiply this pressure with the number of hours that we spend in the screens. Thus we get a large amount of stress which is being applied to our eyes daily.

If by any chance, you are already suffering from some other eye problem and feel the symptoms of CVS then there is a high probability that you’ll be getting more problems to take care of.

By the way, age groups from 8 to 40 are prime suspects for this kind of problem.


Symptoms of CVS

Although science has not proven any serious effect of the syndrome, you must understand that it is time for you to improve your routines. Here are the symptoms of CVS.

  • Double Vision
  • Dry and red eyes
  • Frequent irritation in eyes
  • Blurred Vision in bright light
  • Extensive Tearing
  • Frequent Headaches
  • Pain in Nech and Back


What is the cure?

I know right now you want to know if there is an immediate cure. Let me tell you, there are some remedies that you can do to somehow ease the problem.

The following measures can be taken to minimize the effect of computer screens on our eyes.

  • Regular Breaks for Eye relaxation – Try to take a 20-second pause, after every 20 minutes.
  • Regulate Your Monitor settings – Screens must be set to minimum display if you are working in a well-lighted room. Also, try and avoid working in a dimly lighted room.
  • Adjust the monitor height – According to researchers, the most efficient position for your monitor is slightly below the eye level and placed about 20 to 30 inches away from your face.
  • Comforting posture and workspace – Neck and back pain can be reduced if you have a good and natural posture while working for long hours.


It is undeniable that Computer Vision Syndrome is wide spreading and we should raise our concerns about it. We should not take this problem for granted because in the long run, we are the ones who will suffer.

Hi Everyone! I created this website to share my thoughts about the solutions to various eye problems that are caused by too much staring at digital screens. I also tackle about preventive measures to minimize the harmful effects of UV rays.


  1. Great information to know John! This is very relevant to our day and age!! Teens are probably not even aware of this and we should bring this to the forefront! I have contacts and as of right now I have been staring at this computer screen for well over an hour, which is probably why I get headaches. Does contact wearing make this condition worse? Should I be putting drops in my eyes or just giving them a rest like you said? Thank you for this very informative website!

  2. I’ve never even heart of computer vision syndrome but I suspect I am suffering from it. I do have a couple of the symptoms ie. tearing of the eyes, especially in the mornings and blurred vision with bright light. I’m always rubbing my eyes and my neck often aches.
    Going by your remedies, it would appear that my computer screen is too high; neck ache? Also, I do tend to sit at my computer for long periods of time, especially when I’m on a roll, with a good idea for an article or blog. I really must take heed and rest more regularly.
    I read somewhere that blue light affects your eyes and it’s this light that is emitted from most monitors and tv screen. Have you heard of this? Great post. Ches

    1. Hi Ches! You are right. This blue light comes from the digital screens that you are using like computer, cell phones and tablets. And if you are exposed to it for a long period of time, it may cause the symptoms that you are experiencing right now. Actually, CVS is already wide spreading but people just ignore it.

      There are plenty of eye strain remedies that you can try like eye exercises, computer glasses and even frequent breaks when working. You can check them all if you want and determine which suits you best.

  3. What an informative post, John, and I wish I had this evidence a few months ago when I presented myself to the eye doctor. You see I had a pinguecula, and I wanted him to explain how I had one considering that I don’t spend huge amounts of time in the sun. In which I told him that the only time I’m exposed to excessive light is when I am writing on my laptop. He laughed at me and said if this were the case there would be more people in the world presenting eye problems like mine. But you my friend are right we are having problems with our eyes as a result of looking at screens for too long, and like I said, I wish I found this months ago as I suspect your advice would have prevented the eye operation that I forced to have.

    1. Eye problems are often ignored by most people because it is sometimes associated with other factors. We should also take into consideration the amount of time we spend in front of a digital screen or computers and how it affects our eye sight.

      Although there has been no proven permanent eye damage from looking at the computer, but it still can cause some other problems like eye strain and dry eyes. In the long run, this will develop and cause you more eye problems.

      I hope that people will realize that computer vision syndrome is real and it is wide spreading.
