Over the course of the past three blog posts, we have examined why closer working distance, large pupils, and clear crystalline lenses contribute to children being more vulnerable to the adverse effects of blue light.
So with the “why’s” out of the way, let’s examine the “how’s,” as in, how to help children reduce their blue light exposure and combat digital eye strain.
This is part three in a four-part series guest-written by nationally recognized blue light expert, Gary Morgan, OD.
In parts one and two of this series, we discussed two primary factors affecting blue light exposure: proximity of the light source and pupil size. These factors increase retinal luminance in children viewing blue-light emitting devices more than they do adults.
The third factor affecting retinal luminance is the density of the ocular media that light is passing through. In the eye, the only media that significantly changes density is the crystalline lens.

When considering the impact of blue light on children, most of us immediately think of behavioral tendencies that lead to increased exposure. When we see little Johnny or Suzie immersed in a three-hour game of Minecraft on a tablet eight inches from their eyes, many of us think about the potential consequences of all that screen time on their eyes.
But there are less obvious physiological factors that come into play when considering blue light exposure, and why children are at increased risk.

Kids today are being introduced to digital technology earlier than ever. From speech training to potty training, many boys and girls are learning to tap and swipe before they walk and talk. But while there are obvious benefits to getting our kids ahead of the learning curve on digital technology, there’ a less beneficial result of all that screen time.

In many work environments, you’re not allowed to start your day without proper eye protection. With the ever-growing reliance on blue light emitting devices in the workplace, and the sun’s overly generous blue light contribution to outdoor work settings, it might be a good practice to think of blue-light-reducing eyewear in the same regard.
An office setting typically houses the most forms of blue-light-emitting devices. From desktop monitors to smartphones to tablets to overhead LEDs and/or CFLs, it can feel like blue light is lurking around every cubicle and corner in corporate America.
But while desk jockeys are among those at risk of digital eye strain, they’re not the only ones exposed to blue light after punching in. Here’s a look a three other work environments you may be surprised to find are potential hotbeds for blue light exposure:
