What Is Computer Vision?

Computer vision syndrome (CVS) is a prevalent disorder in our modern digital world. For many people, prolonged computer use causes eyestrain and vision issues. By understanding more about computer vision syndrome, you can take essential steps to prevent and treat it.


Understanding Computer Vision Syndrome


Staring at digital screens all day can take a toll on your eyes. Optometrists have a name for it - computer vision syndrome. Whether using a computer, phone, tablet, or other gadgets, these devices can cause eye and vision problems.


Symptoms of Computer Vision Syndrome


Many people feel uncomfortable after using the computer for just one to two hours. They may experience CVS symptoms such as blurry vision or eye fatigue, making it difficult to focus on the screen. It can also make it hard to switch focus between the screen and other objects. 


Reduced blinking can lead to dry, irritated eyes that feel uncomfortable. Eyestrain from prolonged computer work can also cause headaches around the temples. Poor posture contributes to neck and shoulder pain as you strain to view the screen. Your eyes may struggle to adjust to different brightness levels or become sensitive to light.


Tips for Preventing Computer Vision Syndrome


Preventing CVS requires optimizing your computer workstation setup and work habits. Essential prevention tips include the following:


  • Position your screen 20-26 inches away and slightly below eye level to reduce eye strain

  • Set screen brightness and contrast appropriately for your room lighting

  • Use matte screens or filters to reduce troublesome monitor glare

  • Adjust font sizes for easy viewing without the need for squinting

  • Every 20 minutes, take a 20-second look at something 20 feet away. This lets your eyes relax

  • Blink frequently to prevent dryness and keep your eyes hydrated

  • Use artificial tears if needed

  • Arrange lighting to avoid screen glare and reflections

  • Take regular breaks from the screen to allow your eyes to rest


Treating Computer Vision Syndrome


Do you have computer vision syndrome? If so, visit an optometrist for help. They can prescribe eyeglasses for screen use, vision therapy, or medication like eye drops to soothe dryness.


Blue-light-blocking sunglasses or screen filters may help. Ergonomic workstation changes can help, too. The optometrist will check for any underlying focusing or eye coordination issues that may worsen symptoms. After all, tackling the root causes is vital for effectively treating CVS.




Computer vision syndrome is common among people who use screens extensively. Optimize your computer setup, work habits, and eye care to prevent symptoms. Take steps to keep your vision clear and comfortable while using digital devices. Position yourself correctly, have good lighting, take breaks, and get regular eye exams.
