At the beginning wearing them was a bit special. But after few moments I felt the effect of these classes while working on my phone and computer I usually had headaches etc but now I can work hours without any headache symptoms.
I have a few pairs of Blue Blockers bought from Amazon and other stores - the others sort of do the job but when I tried on the Ra Optics and compared them with my other cheaper ones there was no comparison- the quality improvement was so obvious - it was definitely worth paying a bit extra for something that you will be wearing daily and has the potential to dramatically improve your sleep and overall health - wish I had bought a quality pair to start with as cheaper pairs are a false economy !
Life changing if you havnt conciderd your light enviroment. I will be buying sets for all my loved ones. Until they fix the artifical light problem these glasses work in the meantime. God bless and thankyou!
I really like the design first of all and how it just adds to my flow state in the evening and as a side effect to better sleep and flow state in the morning. Id adds so much to my holistic living.
The entire experience is remarkable!
Who knew being mindful about the entire process of circadian would be so impactful!

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.
