I bought these for my daughter for Christmas and now the whole family, including me, wants a pair. I was a bit skeptical, but I felt more relaxed while wearing them. I wish they were a little less expensive and a little cuter.
I really like these readers. The red lenses filter out the light that keeps you awake. Great for winding down and reading in bedroom. I wouldn’t want to try and watch tv with them but why would you want to do that right before bed anyway? :)
Wish you had an offering that blocked all angles from blue light. Either larger glasses or glasses with blockers on the side, bottom, top… Other than that these things are great. Thank you shaman for the rec.
I love these glasses. I have a small face, and the Clyde style fits perfectly. They have helped me sleep much better because I do schoolwork late. I highly recommend them!
I like the shape of these glasses, it looks cool, but unfortunately, the metal frame is uncomfortable. The frame feels heavy and somewhat bulky, making it difficult to wear for extended periods. Additionally, I can’t use my headset with these glasses, as the earphones press against the metal parts of the frame, causing pain behind my ears. I don’t have any of these issues with other frames, Ra frames and different sunglasses. I'm exchanging it.
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.
