“Our digital world puts unprecedented demands on our visual systems, and these demands are not without consequence, some unprecedented.”

Have you ever heard about computer vision syndrome or digital vision syndrome? As our work lives and recreation increasingly turn towards digital devices, the strain and demands that our digital world puts upon your eyes continues to increase. In fact, uses of these devices can seem inescapable—you’re on one now—as more of our world transitions to digital platforms.

The blue light emitted by smartphones, tablets, computer screens, and televisions can place strain on our eyes, especially during prolonged use, causing discomfort and irritation. The term computer vision syndrome has been coined to describe a wide range of vision issues associated with prolonged digital screen use. If you are experiencing discomfort or strain during or after use of digital screens, Fort Collins Family Eye Care is here to help you gain relief and increase productivity!

What Are the Symptoms of Computer Vision Syndrome?

Computer vision syndrome is a catchall term used to describe a wide range of uncomfortable issues associated with prolonged exposure to digital screens. These symptoms can range from simply annoying to being severe enough to impact your quality of life. You may be dealing with computer vision syndrome if you are experiencing any of the following symptoms during digital screen use:

  • Eye strain
  • Headaches 
  • Watery eyes
  • Blurry vision
  • Double vision
  • Dry and itchy eyes
  • Strained or painful muscles in the neck and shoulders

For some, these symptoms may seem like they’re just part of the deal when it comes to using digital devices, a tradeoff for the convenience of using these devices. The good news is there are options and techniques to help reduce the discomfort and strain of computer vision syndrome. 

Do I Have Computer Vision Syndrome?

It’s possible! In fact, it’s probable. There are a few screening questions you can ask yourself to help determine whether or not you should schedule an evaluation. 

  1. Are you more productive in the morning? 
  2. Do you experience any dry eye symptoms or light sensitivity? 
  3. Do you have frequent headaches or migraines, especially on workdays? 

If you answered yes to any of these questions, take our quiz to find out if you have digital vision syndrome. You don’t have to spend your time experiencing the physical discomfort of our digital world.

Who is At Risk for Computer Vision Syndrome?

Computer vision syndrome does not discriminate. According to WebMD, up to 90% of individuals who use digital devices will, at some point, experience one or more symptom of computer vision syndrome! Individuals with pre-existing vision issues, such as dry eye disease, uncorrected vision issues, or other pre-existing health conditions are more likely to experience symptoms related to computer vision syndrome than their peers.  

Issues related to use of digital screens are not only reserved for adults in the workforce. Children and teens who are more likely to spend recreational and free time on computers and smartphones are increasingly experiencing the consequences of prolonged screen use. The COVID-19 pandemic and the transition to remote learning has only increased the demands on the eyes of young children and teens, causing an increase in digital eye strain and ocular surface disease for these age groups—even in children as young as two! 

What Causes Computer Vision Syndrome?

The root cause of computer vision syndrome for most individuals is the strain placed upon your eyes by repetitive movements and constant refocusing. Essentially, our digital world puts unprecedented demands on our visual systems, and these demands are not without consequence, some unprecedented. Some other factors that increase strain on the eyes and head or neck muscles and contribute to the symptoms of computer vision syndrome include:

  • Poor lighting conditions: Low light conditions or screen brightness settings that do not match the brightness of your ambient lighting can make your eyes work harder when adjusting between the brightness of the screen and the ambient lighting. 
  • Glare or reflections on screen: Glare on your screen from open windows or lighting can make viewing your screen more difficult.
  • Improper viewing distances: Screens that are placed too close or too far away increase the strain on your eyes. 
  • Angle of screen that is too extreme: Screens viewed at too sharp of an angle can increase issues with screen glare and make the eyes work harder to focus on different parts of the screen. 
  • Seating posture: Poor, slumped posture and improper seating position can increase the strain on the muscles of the upper back, neck and head. 
  • Lack of blinking: Insufficient blinking frequency while working at a screen can cause the eyes to become dry and irritated. 
  • Uncorrected existing vision issues: Nearsightedness, farsightedness, astigmatism, ocular surface diseases, and issues with eye focusing and coordination that are left untreated can be exacerbated with digital screen use. 
  • Taking insufficient breaks from screen use: Not giving your eyes sufficient time to rest during demanding screen use can cause symptoms of computer vision syndrome. 
  • Poor contrast: Text on digital screens, especially screens with lower resolution may not be as sharp as printed media, causing your eyes to work harder when reading. 

Often the symptoms of computer vision syndrome are temporary and will often be reduced in intensity or even cease with adequate time away from digital devices. However, it is possible that vision difficulties such as blurry vision or sore and aching muscles from the strain of screen use may continue well after you have stopped viewing a screen because of the inflammation and irritation to your trigeminal nerve. It is important that you take steps to reduce the demands on your eyes and ease the symptoms of digital eye strain. 

Can I Prevent Computer Vision Syndrome?

Prevention is our best treatment. Taking preventative steps to reduce the demands you are placing on your eyes because of the digital world can help you reduce or even entirely avoid some issues related to digital eye strain. Adjusting your work area and habits to accommodate best practices for screen use can help alleviate symptoms associated with digital eyes strain. If you suffer from any of the symptoms of computer vision syndrome, you should try:

  • Adjust your seating posture: Find a chair that conforms to and supports your entire body. Aim to adjust your chair so that you have both feet flat on the ground, your back is comfortably straight, and your arms should be supported without your wrists having to rest on the keyboard. 
  • Change your lighting and reduce glare: Position screens so that they are not receiving glare from windows or overhead lighting. Use drapes to cover windows or use of lower wattage lightbulbs to decrease the intensity of ambient lighting to help reduce eye strain. Anti-glare screens and anti-glare filters are also available if you can’t mitigate lighting or change the position of your screen.
  • Optimal viewing distance and angle: Typically, screens are most easily viewed at 20 to 28 inches away and when the viewer can look downward toward the screen. Having the screen at 4 to 5 inches below eye level at an angle of 15 to 20 degrees is comfortable for most people. 
  • Blink and take breaks: Blinking frequently will help keep your eyes moist and prevent dry eye symptoms. Follow the 20-20-20 rule: every twenty minutes take a break for at least 20 seconds to look at something at least 20 feet away. Additionally, taking a fifteen-minute break every two hours spent working at a screen can help reduce eye strain. Use this time to consult with colleagues, make copies, or complete non-screen related tasks. 
  • Positioning reference material correctly: If you are working with printed or hard copy reference material, use an adjustable stand to place the materials at the same height, angle, and position as your screen. This can help to reduce strain from constant refocusing and repetitive eye movements. 
  • Don’t bring untreated vision issues to work: Prolonged viewing of digital screens when you already have a vision issue can exacerbate both your vision issue(s) and the symptoms of computer vision syndrome. Comprehensive exams, treatment of vision issues, and reducing vision stress are key to easing the strain put on your visual system.
