In our digital age, most of us spend a significant amount of time staring at computer screens, smartphones, and other digital devices. While this technology has brought about many benefits, prolonged use of these devices can cause a range of vision problems and discomfort, collectively known as computer vision syndrome (CVS).


What is Computer Vision Syndrome?


Computer Vision Syndrome (CVS) is a condition caused by prolonged use of digital devices, particularly those with screens. The condition is also known as digital eye strain or computer eye syndrome. CVS can cause a range of symptoms, including eye strain, blurred vision, dry eyes, headaches, neck and shoulder pain, and difficulty focusing.


What Causes Computer Vision Syndrome?


The prolonged use of digital devices causes the eyes to work harder, leading to eye strain, dryness, and discomfort. The screens of digital devices emit blue light, which can cause damage to the retina and disrupt the sleep-wake cycle. Poor lighting, glare, and improper viewing distances can also contribute to the development of CVS.


What are the Symptoms of Computer Vision Syndrome?


The symptoms of CVS can vary from person to person, but they generally include:


  • Eye Strain: Discomfort and fatigue from prolonged screen or reading time.
  • Blurred Vision: Loss of sharpness in eyesight, causing unclear vision.
  • Dry Eyes: Insufficient tear production leading to grittiness and discomfort.
  • Headaches: Dull or throbbing pain around the forehead, often linked to eye strain.
  • Neck and Shoulder Pain: Discomfort and stiffness due to poor posture or prolonged screen use.
  • Difficulty Focusing: Struggles in maintaining clear vision, especially during close-up tasks.
  • Red Eyes: Eye irritation or inflammation resulting in a red appearance.
  • Sensitivity to Light: Discomfort or pain in response to bright light, linked to various eye conditions.
  • Sleepless Nights: Difficulty sleeping due to prolonged screen exposure, affecting the sleep-wake cycle.


These symptoms can be particularly troublesome for people who spend long hours working on computers or other digital devices.


How Can I Help to Prevent Computer Vision Syndrome?


The good news is that there are several ways to prevent or reduce the symptoms of CVS. Here are some tips to help you prevent or manage the condition:


  1. Take breaks: It is essential to take regular breaks to rest your eyes. Follow the 20-20-20 rule, which involves taking a break every 20 minutes to look at something 20 feet away for 20 seconds.
  2. Adjust your screen: Make sure your screen is positioned at the right distance and height. The screen should be at a comfortable distance, about an arm's length away, and the top of the screen should be at or slightly below eye level.
  3. Control the lighting: Ensure that the lighting in your workspace is adequate, and avoid glare from windows or overhead lights. You can also reduce the blue light emitted by your screen by using a blue light filter or wearing blue light-blocking glasses.
  4. Blink more often: When looking at screens, people tend to blink less frequently, which can cause dry eyes. Make a conscious effort to blink more often, or use artificial tears to keep your eyes moist.
  5. Get regular eye exams: Regular eye exams at Urban Optiks Optometry can help detect and correct any vision problems that may contribute to CVS. Your eye doctor can also advise you on the best ways to manage your symptoms.


Now that we've shed some light on computer vision syndrome, you know that it's a common condition that affects so many of us who spend long hours using digital devices. The symptoms of CVS can be prevented or reduced by following the tips above. If you experience persistent eye discomfort or vision problems, it is essential to seek the advice of an eye doctor. By taking care of your eyes, you can continue to enjoy the benefits of digital technology without experiencing discomfort or eye problems.
