The science behind these lenses are undeniable. After spending hours behind a screen everyday, my eyes would become red, puffy, inflamed, and even blurry by days end. Since wearing these daylight lenses (two weeks), my eyes feel so relaxed and display NO irritation. I also have significantly decreased my sleep onset latency and feel much more restored in the morning. Very very impressed.
Haven’t been able to look at a screen for 2 months without going into an awful migraine. Business, life and most other things have been on halt. These glasses have given me that back, plus the yellow lenses make things look like im in a movie. Will most likely get the sunset lenses too now as I try to go for zero tolerance to blue light out of necessity for my health.
Only thanks to RA Optics I can even write this review, such was my predicament before hand. Would recommend the Clyde style too, they look rock n roll
I was very impressed with the professional customer support and product. Works well!
I love the calmness on your eyes. I had my husband try them and he loves it as well that he said to get one for him.
I love these glasses. I noticed an immediate improvement in tension in my face and body. After working at the computer for hours my eyes actually feel rested. Unreal. I love and can't wait to get the sunset lenses.

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.
