Over billions of years, the human body developed an internal clock — the circadian rhythm. It keeps every essential biological process synchronized with the shift from day to night, from sunlight to darkness.
Your body uses blue light as the primary signal to set this clock. A rise in blue light at dawn means: activate, produce stress hormones, suppress melatonin. Darkness and warm firelight after sunset mean: wind down, repair, recover.
That system worked perfectly until we started generating our own light.
Today, artificial light — blue-enriched LEDs in every room, every screen, every pocket — runs at full intensity well past sunset. Your brain receives the same signal it gets at 8am from your phone at 11pm. Melatonin can't rise. The body doesn't shift into repair mode. Sleep is disrupted. Over time, everything downstream suffers: energy, metabolism, immunity, mood, cognitive performance.
This is not a wellness trend. The connection between light, circadian rhythm, and human health is among the most replicated bodies of research in modern biology. Chronic circadian disruption is clearly linked to metabolic disorders, immune dysfunction, neurodegenerative disease, heart disease, and more.
Ra Optics was founded in 2017 by Matt Maruca — who spent years struggling with chronic fatigue, poor sleep, and unexplained health challenges as a teenager. Western medicine had no answers. After years of research, he discovered photobiology: the science of how light affects living organisms at the cellular level.
The insight changed everything. But existing blue light glasses on the market either lacked the spectral science to actually work, or were cheap accessories no one would actually wear. There was no premium, science-based solution.
So, Matt created Ra Optics — the first truly premium, stylish, and science-based blue light protection eyewear — developed in direct collaboration with Dr. Alexander Wunsch, M.D., Ph.D., the world's leading expert in photobiology.
The mission grew from there. Eyewear protects you from the light you can't control — offices, airports, screens, other people's spaces. Lumios fixes the light you do control — your home. Together, they form a complete light environment.
Science that actually filters the right wavelengths. Most clear-lens blue light glasses filter only up to 420nm — a range primarily emitted by sunlight, not screens or LEDs. The wavelengths that disrupt sleep, hormones, and eye health from modern devices sit higher, in the 450–530nm range. Ra Optics lenses are precision-engineered to target exactly that range. Clear lenses don't come close.
Premium materials. Actually wearable. Frames are crafted from Italian acetate, German stainless steel, and aerospace-grade titanium — the same materials used in high-end fashion eyewear. Every lens is shatter-resistant polycarbonate with anti-reflective, hydrophobic, oleophobic, and anti-scratch coatings. This is a product people keep on their face, not in a drawer.
Developed with the world's leading photobiologist. All Ra Optics products are developed and rigorously tested with Dr. Alexander Wunsch — whose life's work is studying how light affects living organisms and how it can be applied therapeutically. This is not a marketing relationship. It's the reason the products work.
Chosen by champions. Ra Optics is the preferred choice of elite athletes, physicians, biohackers, and cultural figures who hold their biology to the highest standard. Aaron Rodgers, Chris Bumstead, Zac Efron, Rick Rubin, Elena Rybakina, Andrey Rublev, Phil Ivey, Ben Greenfield, Paul Chek, and Darin Olien. Not a coincidence.
The original. Ra Optics pioneered premium, science-based blue light protection eyewear. Not a follower brand.
