Computer Vision Syndrome

Definition of Computer Vision Syndrome

Computer Vision Syndrome (CVS) is a collection of eye and vision-related problems that arise due to prolonged use of digital devices such as computers, smartphones, and tablets. It is characterized by symptoms such as eye strain, dryness, blurred vision, and headaches. This condition frequently occurs when individuals spend excessive amounts of time staring at digital screens without breaks, often resulting in discomfort and reduced visual performance.


The phonetic spelling of “Computer Vision Syndrome” using the International Phonetic Alphabet (IPA) would be: /kəmˈpjuːtər ˈvɪʒən sɪnˈdroʊm/

Key Takeaways

  1. Computer Vision Syndrome (CVS) is a common condition that occurs in individuals who spend long hours working on digital screens, causing symptoms such as eye strain, dryness, and discomfort.
  2. Preventative measures against CVS include the 20-20-20 rule, proper screen positioning, and maintaining an ergonomic workspace, which collectively help to reduce eye strain and avoid developing symptoms.
  3. Regular eye exams, appropriate eyewear, and taking breaks from digital screens can help minimize the negative effects of CVS and promote better eye health.

Importance of Computer Vision Syndrome

Computer Vision Syndrome (CVS) is an important term in the realm of technology because it addresses a prevalent health concern that affects millions of individuals worldwide who spend hours in front of digital screens.

With the rise in computer and digital device usage, individuals are at a higher risk of developing symptoms such as eyestrain, headaches, blurred vision, dry eyes, neck and shoulder pain that are collectively known as Computer Vision Syndrome.

By acknowledging and understanding CVS, people can learn about preventative measures or treatment options to mitigate these adverse effects.

Additionally, this allows professionals and organizations to be more attentive to their employees’ well-being, creating a more productive and healthy work environment.


Computer Vision Syndrome (CVS) refers to the collection of eye and vision-related problems that are associated with prolonged computer, tablet, e-reader, and mobile phone usage. The primary purpose of acknowledging and addressing this syndrome is to spread awareness about the increasing consequences and discomfort caused by staring at digital screens for extended periods.

As our daily tasks are now heavily reliant on technology, understanding CVS enables us to develop better habits, tools, and workplace ergonomics designed to keep our eyes healthy and protect ourselves from undue strain. Additionally, addressing CVS can contribute to improving overall productivity and maintaining a better work-life balance.

To prevent or alleviate the occurrence of Computer Vision Syndrome, researchers and experts suggest various remedies and strategies. Some popular solutions include the 20-20-20 rule, in which individuals are advised to take a 20-second break to look at something 20 feet away every 20 minutes when using a digital device.

Others include regular eye check-ups, adjusting screen brightness, and ergonomic improvements such as positioning screens at an optimal distance and angle. Although CVS is not entirely preventable given our reliance on digital devices, awareness and implementation of these preventive measures can help alleviate the strain and stress on our eyes, subsequently enhancing our overall well-being and quality of life.

Examples of Computer Vision Syndrome

Computer Vision Syndrome (CVS), also known as Digital Eye Strain, is a group of eye and vision-related issues that arise due to prolonged use of digital devices such as computers, smartphones, and tablets. Here are three real-world examples showcasing the implications of CVS:

Office Workers: Many office workers who spend long hours using computers experience CVS symptoms, including headaches, eye strain, and blurred vision. With the increasing reliance on digital technology in the modern workplace, it becomes challenging for employees to avoid eye strain, which can ultimately lead to reduced productivity, job dissatisfaction, and a decline in overall well-being.

Students: With the rise of digital and remote learning, students often have to spend hours in front of screens for lessons, assignments, research, and leisure. As a result, they face a higher risk of developing CVS symptoms, which may negatively impact their academic performance, focus, and general health.

Gamers: People who engage in long gaming sessions or work in the gaming industry often experience CVS symptoms due to prolonged exposure to screens. These symptoms can affect their gaming performance and lead to discomfort, as well as potential long-term vision problems if proper precautions are not taken.

FAQ: Computer Vision Syndrome

What is Computer Vision Syndrome?

Computer Vision Syndrome (CVS) is a collective term for a range of eye and vision-related issues that arise from prolonged computer, tablet, e-reader, and cell phone use. It is also known as Digital Eye Strain and is caused by staring at digital screens for long periods.

What are the symptoms of Computer Vision Syndrome?

Common symptoms of CVS include eye strain, dry eyes, blurred vision, red eyes, itching, burning sensation in the eyes, headaches, neck and shoulder pain, and difficulty focusing on the screen. These symptoms may vary from person to person and can be worsened by poor lighting, screen glare, improper viewing distance, or poor seating posture.

How can I prevent or reduce the risk of developing Computer Vision Syndrome?

To prevent or minimize the risk of developing CVS, try the following: take regular breaks from looking at the screen using the 20-20-20 rule, adjust your workstation for better ergonomics, reduce glare on the screen, maintain proper viewing distance, blink frequently to keep your eyes moist, and consider using computer glasses or adjusting your screen settings to reduce eye strain.

What is the 20-20-20 rule?

The 20-20-20 rule is a simple guideline to help in reducing eye strain and CVS symptoms. It suggests that after every 20 minutes spent looking at a digital screen, take a 20-second break, and look at something 20 feet away. This helps to relax the eye muscles and reduce fatigue.

Do I need special glasses for using the computer or other digital devices?

While it is not necessary for everyone to use special computer glasses, they can be helpful for those who experience eye strain or discomfort when using digital devices. These glasses typically have lenses that reduce glare and filter out blue light, reducing the strain on the eyes. If you already wear prescription glasses, you can have lenses made with an anti-reflective coating or blue light blocking capabilities for more comfortable screen usage.
