Below, Dr. Ryan Corte interviews optometrist and fellow Transitions® Change agent, Dr. Jennifer Lyerly, on children’s glasses and blue light protection!
For highlights from this interview, watch the video above!
Dr. Corte: My name is Dr. Ryan Corte and I’m here with Dr. Jennifer Lyerly who is an optometrist, a fellow Transitions® Change agent, an outstanding blogger, and a social media expert. Today we’re gearing up and getting ready for back to school by giving parents insight on children’s blue light protection!
Harmful blue light is everywhere!
Dr. Corte: For parents who may not know, what exactly is harmful blue light?
Dr. Lyerly: Harmful blue light – you’ll often see it abbreviated as HEV when you’re reading articles or looking at it online. HEV means high energy visible light.
It’s a little bit different than UV light, which we think about in regards to sun damage. In both cases, you really can’t see harmful blue light or UV rays coming down (from the sun).
Dr. Corte: What are a few of the main indoor and outdoor sources of harmful blue light?
Dr. Lyerly: Overwhelmingly, the biggest, worst source of high energy harmful blue light is the SUN! Tablets, cell phones, TVs, computers, and LED lights are all sources of indoor blue light.
About 1 hour under direct LED light is the equivalent of about 15 minutes of sunlight. Therefore, the sun is far and away our biggest harmful source.
Dr. Corte: How does harmful blue light effect children’s eyes and overall health?
Dr. Lyerly: As kids, we don’t have any natural, built-in protection from UV light or from HEV blue light.
We know that it can cause quite a few changes to both how our eyes feel and potentially the health of our eyes. This includes eye fatigue and issues with light sensitivity.
There are also some studies that suggest it can be damaging in higher toxic amounts. In addition, there may even be a link with harmful blue light causing early-onset cataract and macular degeneration formation.
