CVS! An Eye Disease of people who are screen addicte

At the present time, we have to admit that smartphones, computers and tablets have become a part of our daily lives, whether for work or rest. However, using them for a long time can damage our sight and the efficiency of vision, especially when you stare at the screen for a long time. Even though this syndrome does not cause severe effects to our eyes or sight, it can cause irritation in our eyes and annoy us while working or in our daily lives. Today, ACU will take you to know more about CVS, an eye disease of digital people.

What is Computer Vision Syndrome (CVS)?

Computer Vision Syndrome is a group of eyes and visual symptoms that result from excessive use of computers, phones, tablets, or digital devices. The severity of symptoms increases with the duration of use. It can be found in both children and adults and may be more vulnerable to this condition if you stare at a screen where there is little light or improper seating while using the computer. The study found that approximately 90% of people who use computers for more than three hours a day experience one or more computer vision syndrome, which can affect their daily quality of life.

The causes of the syndrome

Computer Vision Syndrome is caused by the behavior of staring at a computer screen for a long time or other factors such as distance, light, and reflection from the screen or eye level when we use the computer can cause abnormality to our vision as well. Including the fact that characters on a computer screen are not smooth or there is signal instability in the computer screen. This causes the eye to have to focus more.


  • Have an irritation, pain, sore eyes
  • Dry eye syndrome, which is a temporary symptom.
  • Having blurry eyes caused by an unblinking
  • Slow to focus
  • Having sensitivity to light
  • Headache

     If you have these symptoms more often and longer, they can cause dangers such as dry corneal cornea. 32% of temporary short-sightedness changes can occur. In addition, headaches, stiffness in the neck and shoulders, and back pain from inappropriate sitting posture.

Risk group

Ordinary office workers, writers, graphic workers, students, students studying online, or other professionals who have to sit in front of a computer for long periods.

Prevention and Solution

  • Adjust the visibility and working position. The screen level should be approximately 10 degrees below the eye level. The wrist and arm positions are parallel to the ground. The elbow is perpendicular, and the back should be slightly bent backward.
  • Adjust the font size to the right size, see clearly, adjust the brightness to the level that you feel most comfortable, or choose a screen that reduces reflectivity.
  • Adjust the light from outside and from the computer screen, close the window blinds to avoid any sunlight or light from outside.
  • Blink more often or rest your eyes by closing your eyes, or get up and change your posture for a few minutes every half an hour.
  • For those who usually have short sight, multi-coating lenses should be used to cut light, filter light from the computer screen, save their eyes and reduce the risk of disease.
  • Check eye health regularly or if there is an abnormality that occurs to the eyes, see an ophthalmologist immediately.

     Computer Vision Syndrome is a disease that is very close to us, so we want you to take good care of your eyes, avoid over-exposure and avoid any risk factors that can cause eye harm. For a person who is suffering from this disease, turning to taking care of himself, will help relieve symptoms to be less and recover eventually.
