I Purchased, a pair of Clyde sunset prescription glasses, and have been very pleased. They’re great! My eyes feel better when I wear them. But what’s most important is I know that I’m keeping my circadian rhythm in check, as well as protecting my mitochondria at the cellular level. Thank you!
I wore other redlight glasses for years, but I didn't know what I was missing until I finally upgraded to Ra Optics. Wow, what a difference!
First, these glasses feel amazing on my face, you can tell it's high quality stuff (not the cheap plastic I had from this other company that broke multiple times and the lenses were flimsy plastic falling apart).
Second, I feel a sense of peace and calm when I put these on - it's like my body knows that the harmful artificial lights are being blocked.
Lastly, (and most importantly for my ego haha) I actually look cool and am not embarrassed to wear these in public or with family/friends. For example, blue light blockers on long late flights (especially in different time zones) have been a life saver for me, but I always looked like a frickin' weirdo. Not anymore though, because Ra Optics actually has cool styles. Now, I can feel good AND look good with my light therapy lenses.
So grateful to Matt for taking the time to create science-based effective glasses that look good and cool, feel comfortable on my face, don't completely mess up my color perception (watching a show with my partner on TV with my Ra's on is now possible), and actually help my biology align with the natural cycles so that it can stay healthy, and so that I can have maximum energy to create the life I want.
Plus, beyond light therapy products, I love what Ra stands for. I can't wait to see where the company goes from here.
i've been searching for bluelight glasses for years, and let me save you the trouble- these are the ones. they are perfect. i notice a SIGNIFICANT difference in how my eyes feel after working on the computer, and in how i sleep and how i feel in the morning if i work late at night. they are amazing! would recommend to everyone, and hope to one day get a few different pairs :)
Literally cured my sleep issues. I go to sleep at 10 and wake up at 6 every day now. 5/5
Having never had a pair of glasses for blue light before, I didn’t like wearing them at first because of how they change the color of everything. However, after a couple of evenings wearing them, I love them. They really do make a big difference and I am sleeping much better.
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.
