Just like electro-pollution, artificial light emitted from screens and modern light bulbs is starting to be recognized as a very serious environmental stressor for human biology. In this episode, researcher and entrepreneur Matt Maruca explains how excessive blue light affects our sleep and circadian rhythm, and the best strategies you can use to minimize these effects.
Discussed during this episode:
- How blue light impacts human biology
- How and why you should block excessive blue light during the day, and at night
- Why Matt recommends removing glasses, sunglasses and contacts when you go outside
- Are clear blue-blocking glasses really effective?
- The surprising reason why the light coming from the sides of blue-blocking glasses probably doesn’t matter that much

Thanks Nick for putting all this info about blue blocking out there! And for all other areas you do online. You give out trusted info that everybody can benefit from.
Thanks Connie! Glad you liked the episode :)
Thank you Nick. I am really enjoying and benefiting from your podcasts and your book. I unfortunately fell for the blue reflective coating on my glasses. Ignorance is harmful. I like what you said in a previous podcast – when you know better you do better. I so appreciate and respect your scientific approach to researching and reporting.
Thanks Cathy! This means a lot. Yeah, I still hit myself over the head over this extra 100-120$ I put on my reflective coating… geez. Ignorance sometimes is harmful, and often times costly.
Great information, thanks for this.
I am trying to figure out what type of daytime blue blockers are right for me. Matt seemed to suggest more yellow is better, but he also described conditions that would be found in an office. I work from home, and don’t use artificial lighting much during the day. I just find that I’m spending more time on my electronic devices and want to reduce eye strain. I also have an amber pair for nighttime.
Would 40 or 50% blockage be enough for me?
Hey Stephanie, for general eye strain prevention, a pair of daytime blue blockers that are slightly yellow would suffice in my opinion. Or, simply lowering your computer’s emissions of blue light + brightness could work too. It’s what I do during the day. I use https://iristech.co/ and adjust the settings to what feels comfortable depending on how much natural light happens to come in on that day.
