It's great to be able to offer new lens options. Especially those that differentiate themselves from the rest. The new Blutech display demonstrates clearly how their lenses can benefit everyone's eye health. They are very soothing to wear. I wear these without prescription and see better and feel less eye stress, whether looking at my computer screen or the track lighting/florescent lighting. I have less need to grab for my readers to see the screw heads and frame info. Sold a couple pair so far and have created interest with my clientele. It also sets me apart from other establishments.
