Kids Eyesight Being Affected By Blue Screens

Article Written and Posted by Brulimar - 30th November 2016

Experts have issued a warning that children’s eyesight is deteriorating as a result of blue light from phones and computer screens.


Blue light can cause permanent damage to the retina and, with a wavelength of approximately 380nm to 500nm, it has one of the highest-energy wavelengths. As a result, this causes the wavelengths to flicker which can lead to eye strain, headaches and fatigue when too much time is spent staring at a computer screen or other electronic device. According to experts, children are staring at these screens for far too long, resulting in poor eyesight and an increased risk of developing macular degeneration. 

In fact, optometrists have issued a warning as children are prone to developing the condition; when we’re younger, the lenses in our eyes make it easier for blue light to pass through to the retina and, although this decreases with age, experts are concerned that the damage may be cumulative. This could be a problem for children who will have heavy exposure to blue light throughout their lives. 

Due to the ever increasing popularity of electronic devices, such as phones, tablets and laptops, optometrists are now said to be seeing an increase in problematic cases thought to be caused by blue light exposure. To illustrate, a national survey involving more than 100 optometrists unveiled that 87% of specialists were now frequently treating patients who suffer from eye strain that’s been caused by staring at screens with high levels of blue light. Other conditions included dry eyes, tired eyes, headaches and discomfort caused by the screen’s glare. 

Nowadays, children are becoming increasingly tech-savvy, with many owning their own smartphones at very young ages. This causes an issue for their eyesight; too much blue light exposure can lead to temporary issues, such as visual fatigue, disrupted sleep cycles, retinal damage and, in extreme cases, permanent loss of vision. 

For parents, there are a few tell-tale signs that children may be suffering as a result of blue light exposure. Symptoms include:

  • Dry, itchy, red or burning eyes
  • Double vision
  • Blurred vision
  • Eye strain (pain behind the eyes)
  • Headaches
  • Neck, shoulder and/ or back pain
