Vision Syndrome And Digital Devices

Vision Syndrome And Digital Devices

Almost everyone uses digital devices like computers, tablets, e-readers, and mobile in today’s digital world; recreation, sports, digital learning, education, employment, or any combination of the four. Unfortunately, our increased use of digital devices in almost every aspect of our lives especially now due to COVID-19. Even using a smartphone to make a telephone call requires our eyes to read a computer screen. According to a New York Times article, “Lenses to Ease the Strain from Staring at Screens,” by Mickey Meece, over 30 percent of adults over the age of 18 spend “at least five hours a day on a computer, tablet, or smartphone.” This significant and increased amount of time has led the field of optometry to recognize and identify a visual and upper body muscular disorder now known as Computer Vision Syndrome.

Digital Devices And Visual Challenges  

The American Optometric Association took an early and necessary interest in what came to be known as Computer Vision Syndrome. Their research explains some of the reasons why reading words on a computer varies so much from reading words printed on ink on a paper page. Words are represented on a computer screen with pixels as opposed to ink or laser markings. Depending upon the screen’s pixel resolution, letters of the alphabet can be fuzzy and almost seem to move. Other, more expensive computer monitors with increased pixels can make letters stand out more sharply from the desktop background and thus, make reading easier. The lighting of computers is also different than the overhead or lamplight illumination used when we read words on paper. Paper such as that used for bound books does not reflect light into our eyes, further limiting our ability to differentiate a letter sharply from another. A similar example can be observed when some individuals attempt to read off of glossy magazine pages and find it more difficult than reading a paperback book or an electric company bill.

The physical distance from a desktop computer and the viewing angle can also increase eyestrain. Using a laptop or tablet computer allows the user to modify the distance between their eyes and the screen, only to encourage poor cervical posture similar to a turtle’s head protruding from its shell. Finally, most individuals working at a desk are constantly readjusting their visual focus due to the various distances used for their work, such as reading correspondence, handwriting memos, reading an email online, and switching to office telephone buttons or labels.

Vision Syndrome Symptoms Your Eye Doctor Should Evaluate

The most common symptoms associated with Digital Eye Strain are:

  • Eyestrain
  • Headaches
  • Blurred vision
  • Dry eyes
  • Neck and shoulder pain
  • Worsening of existing eye disorders such as farsightedness, astigmatism, or presbyopia

These symptoms may be caused by:

  • Poor lighting
  • Glare on a digital screen
  • Improper viewing distances
  • Poor seating posture
  • Uncorrected vision problems
  • A combination of these factors

Visit your eye care provider if you experience one or more of the above symptoms:

Treatments for Computer Vision Syndrome

The specific combination of treatment types used to help correct Computer Vision Syndrome is determined by their origin: visual, lighting, postural, or mechanical. In many situations, experts advise computer users to increase word font sizes to minimize squinting and to adjust screen contrast systems so that words appear more distinctly. Some patients will require special computer glasses while others can find relief with the use of an anti-glare computer screen. Dry eyes can be relieved by artificial tears and taking more frequent breaks from computer work.

Un-managed vision problems such as farsightedness and astigmatism, inadequate eye focusing or eye coordination abilities, and aging changes of the eyes, such as presbyopia, can all contribute to the development of visual symptoms when using a computer or digital screen device.

Your eye care provider can diagnose computer vision syndrome, digital eye strain, through an eye exam, with special attention paid to how the eye works and responds at computer distance. Ask your eye care provider today for treatments and techniques to minimize your chances of developing Computer Vision Syndrome, Digital Eye Strain.
