These are super cute, I got tons of compliments when I posted a pic of me wearing them on Insta. I also feel like I am sleeping better and these help me wind down better at night. I typically put them on around 7pm or whenever I'm done with supper. Highly recommend.
Not only are these the best blue blockers I have ever found, from the technology of the lenses, to the sleek style and materials used, RA Optics has the best customer service of any company I’ve worked with in a while!
I couldn’t endorse them enough! I had a minor manufacturing issue with my first pair, they had new glasses in route within 24hrs of my email inquiry, no questions asked!!
Truly an incredible company! I will be an ambassador for them and sing their praises to everyone I meet, without ever being paid ;)
Thank you for your care, integrity, and truly remarkable product. I work a lot on a screen, and am blessed to do what I love, helping people reclaim their health with the luxury of doing it anywhere in the world. These glasses make my my virtual work sustainable and give me the freedom to be location liberated!!
Thank you!!

Have to admit, I had a healthy amount of skepticism when I bought these glasses. But I’m very focused on getting good quality sleep so decided to give them a shot. SO glad I did!! I have an Oura ring & there’s noticeable improvement in my sleep ! I’m a believer! I’m me wearing them nightly forever!!
Hi Susan,

Kind regards,

One word: clarity. Never in my life have I put lenses on that feel like an extension of my eyes like these do. It’s pretty profound. Already feel like they are helping calm my nervous system at night, and I’m falling asleep faster and faster: even if I’m looking at screens right before bed as it happens sometimes. I will be a RaOptics wearer for life. Trust me: they are worth the investment. :)
I have both the daylight and evening clyde’s and they are wonderful. I work in finance and spend a lot of time working in spreadsheets which require meticulous detail and focus. These glasses help my eyes stay fresh and avoid headaches over time. Also great experience wearing the evening lenses as the day winds to an end. TY RA.
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.
