Lightframes & Headphones: What To Look For continued
Many students, artists and athletes in training wear open-eye style lightframes for staying focused. The clear lens frames offer eyes open, peripheral vision stimulation. LEDs in this style are located in the peripheral vision area, allowing for indirect and softer light stimulation. They are often used in EEG biofeedback, and can be used with the eyes open or with the eyes closed.
For the adventurous few that would like to create their own lightframe, try making them out of swim or ski goggles. A friend turned me on to a pair of swim goggles, had the lenses whited-out, placed one white LED at 4 o’clock position in the right lens and 8 o’clock position in the left. He whited-out the half of the LEDs facing the eyes, enabling the reflected pulsed light stimulation to illuminate the entire field of vision. And with the rubber molding between goggles and eye sockets, no outside distractions are visible. You can even use a batting helmet: place the headphones in the ear flaps, attach the lightframes to where the helmet and visor meet, and you have a light and sound helmet that blocks all distractions. Of course it’s best if you are sitting up when you are doing ‘helmetted’ light and sound sessions. But these are just examples of what you can do, should inspiration strike you into creating your own light and sound accessory.
With the exception of the ALLcolor Visual System, most lightframes come in one of two polarities: Common Power (CP) or Common Ground (CG). The polarities are not interchangeable, meaning if your lightframes are CP polarity, they will not work on a CG light and sound instrument, and vice versa.
I always thought it was a rather lousy idea to have two different polarities, because some of my customers own more than one light and sound unit. More often than not, they’d be of different polarities. Customers could not interchange the lightframes, which aggravated more than a few of them, and they let me know how they felt about this unnecessary inconvenience.
