Announcing ŌURA + RA OPTICS

Today at Ra Optics, we are truly honored and grateful to announce a partnership that represents a dream come true.





At Ra Optics, our mission is to inspire people to realize the unlimited potential within themselves. We believe that health is essential to this process, and that light is the most impactful way we can transform health in the modern world. So, we create amazing products to improve health, using light. Our main product is blue light protection eyewear that protects from the harmful effects of man-made light. As a complement to our eyewear, we are also currently developing the most advanced lighting devices in the entire world.


As a company, our primary focus has been on sleep, because this is the main area where man-made light sources cause significant disruption, affecting our entire body negatively.

To spread the message and transform lives with light and sleep, part of our work is regularly partnering with high-level experts, thought leaders, businesses, and celebrities in a variety of ways.

Now, there is one brand that is bringing a huge amount of awareness to the impact quality sleep has on our health. They provide people with truly actionable and useful insights, empowering people to go out and actually improve their sleep. That brand is ŌURA.



If you are not familiar with ŌURA, they are the company behind the Oura Ring—the most accurate and advanced smart ring that provides you with detailed sleep and health metrics—such as body temperature, heart rate variability, activity levels, when you went to sleep, when you woke up, how long you spent in each sleep stage (Light, Deep, and REM sleep), how often you woke up throughout the night, whether you’re experiencing breathing disturbances in your sleep, and more.

Your Oura Ring summarizes all of this data, and more, into three simple daily scores—Sleep, Activity, and Readiness—that tell you where your body stands, and help you to make better health decisions. The best part? It’s a ring. You probably got that from the name, but the ring design means it’s not a bulky wristband or multimillion-dollar specialized sleep study device. It’s ultra-lightweight, comfortable, water-resistant, and looks good with virtually every outfit. It also has a battery life of up to 7 days. And just because it’s smaller doesn’t mean it’s any less accurate — Oura’s sleep staging accuracy is comparable to the gold standard sleep lab test!

ŌURA has become one of the world leaders in the wearable technology industry—trusted by many of the top performers in the world, such as NFL superstar Odell Beckham, Jr., NBA All-Star Chris Paul, 3-time Olympic gold medalist Lindsay Vonn, and professional big-wave surfer Kai Lenny.



Our Partnership

To advance our mission of helping millions of people to transform their life using light, starting with sleep, there is literally no brand that is a better fit than ŌURA.  Hundreds of thousands of Oura Members are regularly measuring their sleep quality every night and looking for ways to improve it so they can feel their best every single day. 

At Ra Optics, we have spent the past five years relentlessly developing the most advanced blue light protection lens technology in the world, for the specific purpose of blocking the harmful blue light from man-made sources that disrupts the body’s circadian rhythm, natural production of melatonin and sleep quality, so that people can begin to actually sleep and recover as we are designed to.

Similarly, ŌURA is on a mission to empower everyone to realize health as a daily practice and feel supported in every step of their journey. They want the world to know that true wellness is accessible to all. They believe that there is a better path to life, and the key to unlocking it is good quality sleep.

In the modern, technology-based world, the single greatest disruptor to sleep is exposure to blue light at night.

How can we say this with such certainty?

We have the data!

What controls the sleep/wake cycle? It’s our circadian rhythm—the internal, 24-hour cycle responsible for regulating sleep and also a variety of the most important functions in our biology. What, then, controls the circadian rhythm? It’s not a coincidence that it follows almost exactly the length of a day. A day is defined by the presence and absence of sunlight on the earth’s surface. Yes, in fact, sunlight controls our body’s circadian rhythm, which regulates our sleep-wake cycle (via the production of key hormones and neurotransmitters such as serotonin, melatonin, and cortisol). Therefore, light is, in fact, the primary regulator of sleep, and the literature couldn’t support this fact more strongly.

So, if you wanted to disrupt sleep chronically, the best way to do it would be to constantly expose yourself to bright, blue-enriched light at night, which is exactly what most of us are doing today in the modern world, thanks to our phones, laptops and even our indoor lighting. Given this reality, and given that it will take some time for the world’s light to be updated to reflect the advances in understanding of how light controls our entire physiology (yes, at Ra Optics, we are working on this), the best thing that one can currently do to improve their sleep in this situation is to protect ourselves from the disruptive effects of blue light at night.

This is why we created Ra Optics, and why it is a perfect fit with ŌURA. The Oura Ring gives you deep, detailed visibility into your sleep quality, helping you better understand the connection between your sleep, your lifestyle, and your health. Ra Optics Sunset Lenses are the simplest and most effective tool for anyone in the modern, technology-based world to actually meaningfully improve their sleep, by protecting from the greatest antagonist to great sleep that we face today: artificial blue light at night.
