Our unique patented Tru-Vu OmniscreenTM
Eyesets have been carefully designed to provide you with the most
and safe light and sound experience. The Tru-Vu OmniscreenTM
Eyeset uses eight high-efficiency, white bulbs mounted over a silver reflector
behind a light blue-tinted translucent screen. This disperses the light evenly,
protects the bulbs and removes any red light which may be produced by the
The maximum intensity of the lights in the eyesets is about 700 lux, spread
out over two square inches per eye. This provides a well distributed illumination
throughout the entire visual field allowing you to move your eyes in any direction
(either up or down, left or right) without interfering with the smoothness
of the light in the visual field. This coverage provided by the OmniscreenTM
Eyeset far exceeds that of any LED eyeset (which have an approximate coverage
of 1/3 of a square inch). When an independent review was conducted of various
light and sound products, the OmniscreenTM
Eyesets rated 100% in light dispersion compared to the next highest rating
of 46.7% for an LED eyeset. In this review, the OmniscreenTM
Eyesets consistently rated the best out of all the other eyesets.
Not only are the OmniscreenTM
Eyesets comfortable, but they are also built to last! They are made from sturdy,
high quality sunglasses. The light bulbs are protected and securely fastened
behind the light blue screen layer. This makes the OmniscreenTM
Eyeset very popular with parents using the DAVID with their children.
Tru-Vu Omniscreen Eyeset with Viewholes - This eyeset is the same as the Tru-Vu Omniscreen Eyeset, but with viewholes cut in them so you can see while running a session. This accessory is popular for athletes who can train while enjoying audio-visual entrainment. Please note that colored overlays are not available for Tru-Vu Eyesets with Viewholes - Please specify when ordering if for Paradise or PAL
Our Tru-Vu OmniscreenTM Eyesets
use tiny incandescent white lights. Most other manufacturers of light and
sound devices use red LEDs. We believe that in order for you to achieve effective
and safe brainwave entrainment, white lights should be used because:
- White lights offer full spectrum stimulation to ensure that the red,
green and blue cones of the retina receive full stimulation similar to natural
- White light has been proven most effective in imagery relaxation and visualization.
- Research with chronic pain patients revealed that red light actually increased
the user's anxiety and pain, however, white light produced beneficial results.
Studies show that red lights actually increase GSR activity and muscle tension.
- A scientific study showed that red LEDs are more likely to cause a photo
convulsive response in people who are photo epileptic.
- White lights "throw" their light in almost every direction.
Red LED light is much more focused and when placed a quarter inch from the
eye, the red LED does not have the distance needed to spread the light out.
- Because red LEDs stimulate only a portion of the total visual field and
the eye is always moving, the "red spot" seen by the eye is always
bouncing about within the visual field. The brain processes this as information
and entrainment is often interrupted as a result.
- Clear encapsulated LEDs make a semi-laser light which may actually burn
the retinas of the eyes if used with the eyes open.
Our new Tru-Vu OmniscreenTM Eyesets
are specially designed to allow for the left and right visual fields of each
eye to be individually stimulated rather than the entire eye. Now you can
experience a whole new dimension to light and sound stimulation! The Tru-Vu
OmniscreenTM Eyesets are so unique
that we have patented both the design and the process.
When using focus during light and sound sessions, the Tru-Vu OmniscreenTM
Eyesets operate the same as with ordinary stimulation. But when using expand,
hemistep or dual frequency, the stimulation is very different with the Tru-Vu
OmniscreenTM Eyesets. This new approach
reduces the brainwave frequency doubling effect that occurs when expand is
used with the ordinary style of visual stimulation.
The visual pathways to the brain are routed via the nerve network called
the optic chiasm. The optic chiasm connects the left visual fields of both
eyes to the right hemisphere of the brain and vice versa.
Because the optic chiasm is wired this way the old, conventional method of
expand rarely produces a visual evoked frequency at the same frequency as
the stimulus. While expand stimulates each eye at different times, both visual
fields and both visual cortexes are also stimulated with each flash of light.
An 8 Hz alternating stimulus will flash in the left eye eight times and flash
in the right eye eight times in one second, generating a visual evoked response
of 16 Hz. In other words, the visual evoked response or brainwave
entrainment (BWE) response is double
the stimulus frequency when using expand or other alternate patterns of stimulation.
With the field-independent method, the eyeset flashes light into the left visual
fields of both eyes, then alternately flashes into the right visual fields
of both eyes. This approach allows the ability to stimulate either visual
cortex with a frequency different from the other visual cortex. For example,
a person who functions strongly from the left brain could have 8 Hz stimulated
into the right visual field (and therefore the left brain) to slow down left
brain function and have 18 Hz stimulated into the left visual field to increase
right brain function. Using spectral analysis EEG, we have seen evidence of
All of the DAVID Paradise products also include three color overlays. These
overlays are colored filters that fit over the OmniscreenTM
Eyesets to allow you to experiment with different colors when using your
DAVID. Each DAVID Paradise comes with yellow, green and violet color overlays.
Ruby and indigo are also available for an additional charge.
