Studies show that adults spend around nine hours of their day in front of digital screens. This can wear out the eyes, causing headaches, dry eyes and blurred vision. In this post, your eye doctor from the Institute for Control of Eye Myopia in Children discusses why digital screens cause eye strain.
How Screens Affect Your Vision
Digital eye strain, also known as Computer Vision Syndrome, is similar to other repetitive motion injuries, like carpal tunnel syndrome. It occurs because your eyes keep following the same path over and over again. The longer your exposure, the worse your symptoms are going to get.
While facing the computer, your eyes focus and refocus repetitively. They move up and down or back and forth as you read and look down at your papers. These movements can take a toll on your eye muscles. Contrast, flicker and glare from the screen, as well as not wearing the correct prescription glasses, can make your eyes work even harder.
As you age, the lenses in your eyes get more flexible, affecting your ability to focus on nearby and faraway objects. This eye condition is called presbyopia, and is common among people over 40.
Symptoms and Treatment
Extended exposure to digital screens have no proven long-term effects on the eyes, but it can cause discomfort. Common symptoms of digital eye strain include blurred or double vision, dry, red eyes, irritation, headaches and back or neck pain.
Visit your optometrist if you’re experiencing any of these symptoms. Not addressing them may affect your productivity in the workplace.
Small changes in your workplace can help relieve symptoms of eye strain. Make sure you have good lighting and that your computer screen isn’t too dark or bright.
It’s advised to position your monitor slightly below eye level, around 20-28 inches from your face. To give your eyes a break, practice the 20-20-20 rule where you look 20 feet away from the screen every 20 minutes for 20 seconds.
It’s a good practice to undergo a routine eye exam to make sure your vision and eye health are in good shape.
