FAQs on Computer Vision Syndrome

A Study by the Department of Community Medicine, Shree Balaji Medical College Chennai, revealed that CVS was 63.9% prevalent in IT professionals working for 7-10 hours on computers.

Yet another study conducted by the University of Colombo, Sri Lanka, and the Ministry of Health Care and Nutrition, Colombo, Sri Lanka—found that CVS was prevalent 75-90% among computer users.

Note: The prevalence rate indicates the prevalence of CVS symptoms as defined by the American Optometric Association.

Computer Vision Syndrome—A byproduct of the Information Age.

Our visual system has evolved over thousands of years to adapt to natural lighting conditions and outdoor environments. Historically, our eyes received a balanced dose of light, distance viewing, and regular breaks from close-up work. However, with the rise of computer-based offices and the increasing reliance on digital screens, our visual system faces new challenges.

Computer Vision Syndrome (CVS) arises from the abrupt shift to prolonged screen use without adequate visual breaks. Unlike traditional office setups that offered natural pauses between tasks, digital devices demand continuous near-focused vision, causing eye strain and fatigue. 

The constant visual demands, reduced blink rate, improper viewing distances, and screen glare contribute to the development of CVS.

This modern lifestyle disrupts the natural rhythm of our visual system, leading to discomfort and prevalent CVS symptoms.

What is Computer Vision Syndrome?

 Computer Vision Syndrome (CVS) is an eye condition that needs to be understood in the context of neuroscience. Our visual system and the brain work in harmony to process and interpret visual information. When we engage in prolonged screen time, our visual system undergoes certain changes that can impact our neural pathways and visual processing.

In the case of Computer Vision Syndrome, the constant focus and strain on digital screens disrupt the natural balance of our visual system. This imbalance can lead to neurological adaptations, such as altered neural firing patterns and reduced visual acuity. The repetitive and intense visual demands of digital screens can also overstimulate certain neural pathways while neglecting others, causing an imbalance in visual processing.

Neuroplasticity, the brain’s ability to reorganize and adapt, plays a role in the development and persistence of Computer Vision Syndrome. The brain may undergo changes in response to prolonged digital screen exposure, affecting visual perception, attention, and even overall cognitive function.

Computer Vision Syndrome Symptoms

 Computer Vision Syndrome Symptoms can manifest in various ways, affecting individuals who spend significant time using digital devices. Common Computer Vision Syndrome Symptoms include:
  • Eyestrain, which can present as sore, tired, or burning eyes. 
  • Dry eyes, characterized by a lack of moisture or a gritty sensation. 
  • Blurred vision.
  • Difficulty in focusing on nearby or distant objects. 
  • Headaches due to visual fatigue, often originating from the forehead or temples. 
  • Neck and shoulder pain, resulting from prolonged poor posture.
 

The relation between CVS and Digital Eye Strain

 Computer Vision Syndrome (CVS) and Digital Eye Strain are closely related conditions that often go hand in hand. Digital Eye Strain refers to the discomfort experienced after prolonged use of digital devices, such as computers, smartphones, and tablets. It encompasses symptoms like eyestrain, dry eyes, blurred vision, and headaches. CVS, on the other hand, encompasses a broader range of eye and vision problems resulting from prolonged digital screen exposure. 

One might say that persistent Digital Eye Strain can lead to CVS—or, say, Digital Eye Strain is one of the common Computer Vision Syndrome symptoms.

Computer Vision Syndrome Causes

 Computer Vision Syndrome (CVS) can be attributed to a combination of factors related to prolonged digital device use. Understanding these causes is crucial for effectively addressing and managing Computer Vision Syndrome symptoms.
  • Continuous focusing demands of digital screens: Unlike printed materials, screens have pixelated images that require the eyes to work harder to maintain focus. Additionally, improper viewing distances and angles contribute to CVS, as being too close or too far from the screen can strain the eyes.
  • Poor lighting conditions: Insufficient ambient lighting or excessive screen brightness can create contrast issues, leading to eye strain. Screen glare from overhead lighting or reflections further adds to the discomfort.
  • Reduced blink rate: When focusing intently on screens, people tend to blink less frequently, resulting in dry and irritated eyes.
  • Uncorrected vision problems: Eye disorders such as farsightedness or astigmatism, can exacerbate Computer Vision Syndrome symptoms. Vision imbalances force the eyes to work harder, leading to increased strain and fatigue.

Can Blue Light cause CVS? Yes!

 Blue light, a type of high-energy visible (HEV) light, is emitted by various digital devices such as smartphones, tablets, and computer screens. Exposure to excessive blue light can cause eye strain, dryness, and fatigue. It can disrupt the sleep-wake cycle by suppressing the production of melatonin, a hormone that regulates sleep. Prolonged exposure to blue light may contribute to digital eye strain and CVS.
 

Moreover, studies suggest that long-term exposure to blue light may be linked to increased risks of age-related macular degeneration (AMD). AMD is a leading cause of vision loss and affects the central part of the retina, impacting sharp and detailed vision.
