This extensive use of screens provoked debates about the potential effects on the children’s visual and overall health.

Digital Eye Strain: A Common Consequence

One of the most significant problems related to the excessive use of screens by children is the problem of digital eye strain sometimes referred to as computer-vision syndrome (CVS). Digital eye strain can cause various symptoms, such as:

  1. Eye Fatigue: The use of screens for long periods can result in tired eyes and fatigued eyes making it difficult for children to focus on other activities.
  2. Eye Dryness: Screens can cause a reduction in the blinking rate, leading to dry eyes and irritation.

  4. Blurry Vision: Extended screen usage can cause temporary blurred vision, which makes it difficult to see distant objects.

How Does Screen Time Impact Eye Health?

Many factors can contribute to the negative effects of screen time children’s eyes:

  1. Blue Light: Exposure Screens emit blue-coloured light that is believed to alter sleep patterns and may cause strain on the eyes of digital devices. Exposure to blue light for long periods particularly prior to bedtime could disrupt your body’s natural circadian rhythms, making it difficult for children to sleep.
  2. Blink Rate: Reduced In the case of being occupied by screens, children are likely to blink less often. Blinking is crucial to hydrate the eyes and stop dry eyes. Insufficient blinking can cause dry, uncomfortable eyes.
  3. Close-Up Viewing: Children frequently keep the screens close to their faces than when using print-based materials. Close-up viewing may cause more strain of the eye’s focus mechanism, creating strain on the eye.
  4. Reduced Outdoor Time: Excessive screen time often replaces outdoor activities. Being outdoors can be beneficial to children’s overall health and eye health, because it gives them a break from the stress of screens.

While screens are a vital aspect of our lives but there are steps that parents and caregivers can take to reduce the adverse effects of prolonged screen time for children’s eyes:
