Since wearing RA optics I have had so much more energy and way less headaches. It has changed the way I go about my day and my energy level is so much better. I am not barely able to keep my eyes open at work or in bed by 9 anymore thanks to these glasses. I would recommend them to anyone I know who works with screens all day.
My fiance absolutely loved these!!!
I have been wanting a stylish pair of lblueblockers for awhile. I love the Yogandas I have them in yellow and orange. They are super comfortable with a great lens.

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.
