What is Computer Vision Syndrome (CVS)?
Computer Vision Syndrome or CVS is a group of eye and vision symptoms resulting from prolonged use of computers, tablets, or mobile phones, including the behavior of looking at a computer screen closer than half a foot or about 6 inches.
The severity of symptoms increases with the duration of use. This condition can be found in both children and adults and may have a higher risk if staring at screens in low light or having improper posture while using them.
Causes and contributing factors include
- Reduced blinking while focusing on reading or staring at a computer screen, leading to dry eyes
- Inappropriate indoor lighting
- Glare from the computer screen
- Text on the computer screen not being as sharp as printed text or unstable signals on the screen, causing the eyes to work harder to focus, leading to eye fatigue
- Improper posture while working
Symptoms
- Burning sensation, eye discomfort
- Eye irritation, eye pain
- Blurred vision from reduced blinking
- Temporary dry eyes
If these symptoms occur frequently and progressively worsen they may cause complications such as dry keratitis and temporary myopia, which occurs in up to 32% of cases. Additionally, headaches, neck pain, shoulder pain, and back pain from improper posture may also occur.
Who is at risk for Computer Vision Syndrome?
- General office workers
- Writers
- Graphic designers
- Students attending online classes
- Individuals who work in front of a computer for extended periods
Treatment
- Doctors will examine and explain the condition to the patient
- It is recommended for those who use their eyes extensively for long periods to use artificial tears to help reduce burning and dry eyes
Prevention
- Rest your eyes, such as closing them every 10 minutes for every 1 hour of computer work or taking breaks every 15 minutes during 2 continuous hours of work
- Set up the computer in a place with adequate lighting to help ease eye strain
- Use screen filters to reduce glare and reflections, which can help reduce eye fatigue
