We are now spending almost half our waking hours using digital devices for everyday tasks such as work, socializing and shopping. Research has shown that up to 65% of users are experiencing some form of discomfort.*

What is Digital Eye Strain?

Digital Eye Strain is the term used to describe physical discomfort to the eyes after prolonged work on a digital device. This usually occurs after two or more hours of activity. While the symptoms can vary from person to person, they can be quite mild or severe. Typically people experience one or more of the following symptoms.

  • Tired eyes or fatigue
  • Dry, red, burning or itchy eyes
  • Headaches, and pain around the eyes
  • Blurred vision
  • Neck and shoulder pain

  • What happens when we use a digital device?

    When we look at near objects the eyes need to convergence together and focus to maintain clear vision. With prolonged near work the muscles in the eye can fatigue leading to discomfort. Our blink rate also naturally reduces when we concentrate on near tasks and this can lead to symptoms such as dry, gritty red eyes. We are increasingly using smaller devices with brighter screens which put extra strain on the visual system. These devices are often hand held, and this tends to change our posture putting strain on our neck and back.

    Digital devices emit blue light which is known to disrupt our nature sleep patterns and can cause eye strain.
