Read many reviews of people that swore by the "sleepiness/relaxed" sensation experienced while wearing the lenses. Wanted to try them out since the science made sense and found that the yawns are triggered (at least for me) every time. Love em 100% !
These glasses really help to fall asleep. Eyes feel much more relaxed and not so stressed during evenings. Worth trying if having troubles with sleep.
I lent my glasses to my mom for her to try them after she has had some bad sleep lately. We are three days in to that test. Two nights of better sleep later, I have a feeling I'll never get those glasses back...
Taking care of my eyes is important, that’s why I don’t want cheap optics, so happy I got these
I sleep better mate
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.
