Nathaniel Kleitman was an American physiologist and sleep researcher who served as Professor Emeritus in Physiology at the University of Chicago. He is recognized as the father of modern sleep research, and is the author of the seminal 1939 book Sleep and Wakefulness.

I ordered a pair of Sunset lenses with my Daylights. I already owned a pair of amber glasses, but I wanted to see how these compare - and the RA Optics lenses are so much better. I'm much more relaxed at night, my body is telling me to sleep earlier and my sleep has radically improved since wearing them. I'm certain my previous pair were leaking blue and green light since trying these. 100% recommend them
I found immediate results from my RA Optics! Less eye strain. Easier to fall asleep. I can just feel an entire shift in my body!
I’ve had sleep issues ever since I started working overnight shifts 2 years ago. I since switched back to a regular shift but have been feeling burn out and “wired but tired” no matter how long I slept. Since using these glass I’ve noticed a significant impact in my bodies ability to wind down and prepare for sleep. It’s like my system started producing its own melatonin again, and all I needed to do was block the harmful blue light in the evening. I cannot recommend these enough!
My a Oura deep sleep score has always been terrible. These are the first thing to ever improve it.
I LOVE these glasses and I look cool too in my house at night! Ha. Really though, now that I have them I can imagine how wired I was viewing various screens at night. I take them off for a second just to see the difference and it’s huge. My sleep has been so much better…back in a good circadian rhythm.
Finding yourself inside, staring at screens day and night? You need to protect your health from the damaging effects of all that artificial blue light. Ra Optics glasses are scientifically-proven to block 95-100% of artificial blue light, saving you from poor sleep, eyestrain, headaches, and feeling fatigued.
For years I searched for a treatment that would heal - not mask - my underlying health issues. What I uncovered changed everything about the way I thought about light, sleep and my health. Keep reading to learn how Ra Optics’ Blue Light Blocking Glasses have made all the difference.
We started with science then made it stylish. Our glasses have been developed with leaders of photoscience, neuroscience, and optics. They are infused with pigments that have been tested and retested for effectiveness. We personally know they work, but many leaders in health and fitness can attest to that too.
