What if the light you’re exposed to every day is quietly disrupting your hormones, energy, and long-term health? In this episode, I sit down with Matt Maruca, founder and CEO of Ra Optics (@ra_optics), to explore how light—both natural and artificial—affects your body at a cellular level, and why most of what we’ve been told about blue light is incomplete.
Matt shares the personal health crisis that launched his deep dive into light science, and how his understanding has shifted from binary "block all blue light" thinking to a more nuanced view of spectrum, timing, and biological context. We discuss why certain wavelengths of blue light are essential for circadian health while others cause oxidative stress, how modern lighting creates a mismatch with our evolutionary biology, and what happens when your eyes and brain are flooded with artificial light stripped of balancing wavelengths like near-infrared.
We also get into practical strategies: when sunglasses actually help versus harm, how to structure light exposure throughout your day, why sunrise and sunset matter more than you think, and how emerging lens technology is evolving to meet the needs of our screen-heavy lives. This conversation will change how you think about the light around you—and give you actionable tools to protect your biology in a modern world.
