Screen fatigue, also known as computer vision syndrome, is a group of disorders that develops from moving your eyes in a repetitive motion. When you work at a computer, your eyes have to focus and refocus consistently as they move back and forth as you read across your screen. Often, you look down at papers or any other objects that are located on your desk. Your eyes are constantly moving and changing, shifting focus, and all these jobs require a lot of effort from your eye muscles. Due to the COVID-19 pandemic, there is increased use of screen time for most people in nearly every aspect of our lives. We rely on screens for everyday occupations such as running meetings to engaging in religious services, leisure activities and hobbies.
Unfortunately, excess screen time comes at a price. If you are experiencing blurred vision, dry and red eyes, eye irritation, double vision, headaches and neck or back pain, you may be experiencing screen fatigue syndrome. To reduce screen fatigue symptoms, try to cut the glare on your computer screen by changing the light around you. You could also try rearranging your desk so that your monitor is slightly below eye level and approximately 20 to 28 inches away from your face. Follow the 20-20-20 rule, which means looking away from the screen every 20 minutes or looking 20 feet away for about 20 seconds. If you are still experiencing symptoms of screen fatigue, visit your eye doctor and let them know about any problems you have.
