Expand your Procyon experience—and your mind--with our new DeepVision eyes-open (Ganzfeld) glasses. When you are using them with your Procyon, your entire field of view is filled with pure, jewel-like colors and dancing patterns, and the two RGB LEDs per eye assure plenty of brightness. When the LEDs are all at maximum brightness, white light is produced. It works well with your eyes closed, too! We’ve wrapped the attractive lightweight shell with soft, hypoallergenic silicone, with lips at the top and bottom to help block out ambient light, for a more immersive experience. Note: these are not compatible with our other models or on their own, but are for use with the Procyon only, and only with Procyon Rev 3 and 4, those with a round plug and jack.
