Digital Eye Strain

Digital Eye Strain: A 21st Century Issue

You would expect to feel sore and tired after a day of manual labor. But what about a day of computer work? Many people spend all day working online, only to find their eyes feeling heavy, and their necks feeling tight. This discomfort is caused by digital eye strain, and it may be affecting you right now.

Symptoms of Digital Eye Strain

The symptoms associated with computer vision syndrome or digital eye strain will vary depending on a person’s quality of vision and the amount of time they spend in front of a computer. Here are just a few of the symptoms associated with DES:

  • Fatigue
  • Heavy eyelids or difficulty keeping eyes open
  • Headaches
  • Neck pain
  • Burning or itching eyes
  • Excessive tears
  • Dry eyes
  • Blurring or double vision
  • Sensitivity to light

What Causes Eye Strain?

Imagine crouching down in a squatting position. At first, it feels fine; maybe even comfortable. But after a few minutes, your knees start to get sore and your back starts to ache. Now imagine holding that position for eight hours; you would probably be in a lot of pain. That’s similar to what happens when you experience eye strain.

You see, your eyes use muscles to focus on any given point. When you focus on the same point or points at the same distance for hours at a time, those muscles start to get sore and fatigued.

The idea of staring at the same point all day is hardly new; people have done book-work for centuries, so why is digital eye strain worse than the eye strain you would get from reading a book?

The answer is blue light.

Blue light is a specific frequency of UV light emitted by phones, laptops, and other digital displays. This type of light has a tendency to scatter, which makes it harder to focus. As a result, the eyes have to work even harder to make sense of what they’re seeing.

Vision problems caused by prolonged digital display usage can also be exacerbated by:

  • Glare on the screen
  • Poor lighting
  • Improper viewing distance from the monitor
  • Bad posture
  • Uncorrected visual error

Avoiding Digital Eye Strain

While you may not to be able to avoid digital screens in your daily life, you can employ a few simple strategies to help you avoid the symptoms of digital eye strain.

People blink about 12 times per minute on average. That number dwindles to about 5 times per minute during screen use. It may sound silly, but remembering to blink can help keep your eyes hydrated and alleviate your symptoms.

Every 20 minutes or so, step away from your computer, choose an object that’s 20 feet away, and stare at it for 20 seconds. This is known as the 20/20/20 rule, and it’s the ocular equivalent to getting up to stretch your legs.

We carry a special lens coating that helps filter out some of the blue light emitted from digital displays. With less blue light to focus, your eyes don’t have to work quite as hard.

Ensure your screen is an arm’s length away from you, with the top of the screen roughly 20 degrees below eye level. Keep your screen clear of any dust or fingerprints, and try to position it to minimize glare.
