In this episode, Matt Maruca, CEO and co-founder of Ra Optics, dives deep into the science and practical realities of blue light, circadian health, and optimizing your environment for better sleep and longevity. We tackle the nuances of blue light exposure from sunlight versus artificial sources, break down how proper blue light-blocking glasses can support melatonin production and overall wellness, and bust common myths—including those from recent documentaries and reviews. Along the way, Matt shares updates on the latest lens technology, why not all blue blockers are created equal, and the future of lighting and color therapy for health.
Matt Maruca is the founder & CEO of Ra Optics, the leader in premium blue light protection eyewear. Matt founded Ra Optics after a decade-long journey to improve his own chronic health issues as a child and teenager.
As he looked further, he came across the science of mitochondria, circadian rhythms, and how light influences these factors—playing an essential, but overlooked, role in our health and well-being. He became fascinated by entrepreneurship, and decided that he could use the in-formation that helped him to help others.
Matt also created The Light Diet, a diet that directly addresses the root of the modern, chronic disease epidemic and mitochondrial dysfunction. Matt now spends his time traveling the world, studying and teaching about the relevance of light in human health cycles with a focus on reversing this situation, as well as integrating science with ancient Eastern wisdom.

| 0:05.0 | Most people are seated all day long when they're indoors, so spiking their cortisol level |
| 0:09.7 | and raising their blood sugar is not actually going to be desirable. |
| 0:13.2 | For example, high blood pressure, it can actually be a contraindication to use blue-enriched |

| 0:48.2 | Did you know there is a mineral that can balance hormones? A lot of times we hear about hormones. I think, oh, do testosterone and DHA and Pregnitalone and progesterone and blah, blah, |
| 0:53.5 | blah, but there's actually a mineral that you have to have that's critical for also supporting your |

| 1:27.7 | that's poorly absorbed, and it's not all the types of magnesium. A lot of people take just one |
| 1:32.0 | to two forms of magnesium when there's actually seven different forms. And many nutritionists and |
| 1:37.9 | clinical experts believe that it's best to take a combination of different magnesium forms, |
