As the world becomes more digital, many of us have found ourselves spending more time in front of screens, be it for work, education, or entertainment. This shift has led to an increase in a condition known as computer vision disorder (CVD).

What is Computer Vision Disorder?

What is computer vision disorder? Simply put, it's a condition resulting from focusing the eyes on a computer display for uninterrupted periods of time. Some symptoms of computer vision disorder include headaches, blurred vision, neck pain, redness in the eyes, fatigue, eye strain, dry eyes, irritated eyes, double vision, vertigo/dizziness, and difficulty refocusing the eyes.

These symptoms can be further aggravated by improper lighting conditions (i.e., bright overhead lighting or light coming from behind), glare on the digital screen, the improper viewing distances, poor seating posture, and uncorrected vision problems. The extent to which individuals experience these symptoms can vary depending on the level of their visual abilities and the amount of time spent looking at the digital screen.

The Causes of Computer Vision Disorder

Computer vision disorder is caused by our eyes and brain reacting differently to characters on the screen than they do to printed characters. Our eyes have little problem focusing on most printed material, which is characterized by dense black characters with well-defined edges. But characters on a computer screen don’t have this contrast or well-defined edges.

These characters (pixels) are brightest at the center and diminish in intensity toward their edges. This makes it very difficult for our eyes to maintain focus and remain fixed onto these pixels. Instead, our eyes want to drift to a reduced level of focusing called the 'resting point of accommodation' or RPA.

How to Alleviate Computer Vision Disorder

When it comes to learning how to alleviate computer vision disorder, a few simple changes to your workspace and work habits can make a significant difference. Firstly, ensure that your workspace is set up in a way that minimizes discomfort. Adjust your monitor to the correct height, make sure you have proper lighting that reduces glare, and take regular breaks from staring at your screen.

Adjusting your digital habits can also go a long way in reducing symptoms. Take frequent breaks. Try to take a 10 minute break for every hour of using a digital device. This helps to rest your eyes and prevent strain. It’s also important to blink frequently to keep your eyes moist and reduce dryness and irritation.

Professional Treatments for Computer Vision Disorder

If these self-care tips aren't enough to alleviate your symptoms, it may be time to seek professional help. Optometrists can provide treatments such as specialized glasses or contact lenses designed for computer use. These lenses can help to create a more optimal eye focus and reduce strain.

Eye exercises and vision therapy may also be recommended to help strengthen your eyes and improve your visual efficiency. In some cases, medications may be prescribed to help alleviate symptoms. It's important to discuss all your symptoms and concerns with your optometrist, as they can provide the best treatment plan tailored to your needs.
