Color therapy glasses are a great way to incorporate color therapy into your life! Wear different colors to elicit distinct moods and states. Chromotherapy (Color Therapy) is a proven therapy, not just in holistic health but also in traditional, Western healthcare.

Current studies concluded that Color Therapy is a natural way to cure various ailments and is utilized world wide. Read more about these findings HERE.

We naturally associate colors with emotions and feelings. We say, "I'm green with envy," or "You're yellow bellied," or "I see red!" or "I'm feeling blue," or "I'm in a black mood." With color therapy, each color is associated with particular emotions and feelings. Colors each have different frequencies and vibrations. When a particular color frequency enters our body, by wearing color glasses, for example, that vibration can have an effect on our emotions. It is easy to become out of balance. The appropriate color may allow our feelings and emotions to return to a balanced state and we'll feel better.

Violet (Purple): Inspiration, calm nerves, reduced irritation, creativity, beauty.

Indigo: Serenity, imagination, accurate perception, understanding, strong deep sleep.

Blue: Mental relaxation, peace, calmness, vitality, creativity, clear communication.

The Sacred Solfeggio Tuning Forks are a set of forks in the sacred frequencies known as the Secret Solfeggio.

Deciphered by Dr. Joseph Puleo using the ancient Pythagorean method of reducing the verse numbers to their single digit integers, the codes revealed a series 6 of electro-magnetic sound frequencies that correspond to the 6 missing tones of the ancient Solfeggio scale. These original sound frequencies were used in Ancient Gregorian Chants. The chants and their special tones were believed to impart tremendous spiritual blessings when sung in harmony during religious masses. These frequencies can now be produced with the Sacred Solfeggio Tuning Forks.

Sound healing using the Solfeggio frequencies has been proven as an effective tool in healing generational trauma and DNA. Read more about the research here.

Included forks and frequencies

UT (ut quent laxis) Liberating Guilt & Fear ... 396 Hz RE (resonare fibris)

Facilitating Change & Support ... 417 Hz MI (mira gestorum)

Transformation & Miracles DNA Repair ... 528 Hz FA (famuli tuorum)

Connecting & Relationships ... 639 Hz SOL (solve polluti)

Awakening Intuition ... 741 Hz LA (labili reatum)

Returning to Spirit ... 852 Hz

The Sacred Solfeggio Tuning Forks are available in either the original set of 6 or in the complete set of 9 forks, which includes the 3 missing notes (174 Hz, 285 Hz, & 963 Hz.)

Each kit includes a velvet pouch.

Please note the frequencies of the weighted set are different from the unweighted Solfeggio tuning fork set. The frequencies of these forks are proprietary.

Should I choose Standard or Weighted?

Which style is right for you? Standard tuning forks are great for vibrational healing such as sound toning and for working with energies, such as opening energy blocks, clearing chakras, or cleansing auras. In the process of promoting the flow of vital life force within the human body and the human energy field, they are intended to assist and facilitate clearing, balancing, and energizing the energy body in a simple and gentle way. Standard tuning forks also have the unique quality of being able to produce harmonic intervals (multiple pitches that occur at the same time) when struck together. Weighted tuning forks don't produce harmonic intervals as easily, however they have a much stronger vibration, making them easier to feel, and excellent for uses such as acupuncture, sound puncture, and muscle relaxation techniques. In addition to their own sound and vibrational healing qualities, weighted tuning forks can physically transfer their frequency of vibration to the body by using forced resonance, or by directly applying the handle (also called stem) of the tuning fork on the body at point of focus, such as a meridian or chakra. This is a way of creating movement or frequency vibration in any area of the body, and as such, weighted tuning forks are known to give immediate relief from pain when used with interferential therapy techniques. Weighted tuning forks vibrate for longer periods of time and stay at their exact frequency longer. This makes them great for accurate or precision tuning or toning when doing sessions on yourself or others.

Weighted Frequencies are different from Unweighted: 69.5 Hz RE, 66 Hz UT, 88 Hz MI, 106.5Hz FA, 123.5 Hz SOL, 142 Hz LA

About our Tuning Forks Our tuning forks are made from a special Aluminum Alloy that is heat treated giving them a very pure tone. The single fundamental frequency will remain constant for up to 15-20 years and the non-tarnishing material will not rust or corrode. Each fork is tuned by hand to an accuracy of /- 0.25% or better.

Please do not confuse our tuning forks with inferior products being made in China and Pakistan.

The Otto tuners are used for relaxation, as the sound vibrates into the bones and releases tension.

The Otto Tuners are tuned to the frequencies of 32cps, 64cps and 128cps.

They vibrate at a low pitch and due to their weighted ends, the sound lasts longer than that of regular tuning forks. Their frequencies are based on an 8 cps fundamental tone raised in octaves (i.e. 8 cps, 16 cps, 32 cps, 64 cps, 128 cps.) The 8 cps fundamental, which based on the pulsation of the planet earth, is the generating tone for all our tuning forks. The 128 Otto Tuner is especially effective when placed on the rib heads, thoracic vertebra, sternum and ileums.

Two Otto Tuners tapped gently on the knees and held to the ears create a beautiful sustained low tone, which is excellent for grounding and relaxation.

The 64 Otto Tuner is especially effective when placed on the lower lumbar vertebrae, sacrum and coccyx. Its vibration helps loosen the sacral ligaments as well as stimulating and balancing the ganglion of impar, a center for controlling the balance between the sympathetic and parasympathetic nervous system.

The 32 Otto Tuner works with your skin and hair to stimulate nerves. Otto Tuners are available in three Different Frequencies: 32, 64 and 128 Hz. It is recommended to start with the Otto 128.

Instructions

For using the 128 and 64 Otto Tuners with bones and ligament, hold the forks by the stem and gently tap them on your knee. With the finger or thumb of your free hand locate the spot on the body where you want to place the tuning fork. Press the end of the stem of the tuning fork onto the spot. Make a firm contact and hold the tuning fork until you feel the vibrations stop. For listening, hold the 128 Otto Tuner by the stem and gently tap the weights on your knees or tapping pad. Bring the tuning fork(s) to your ears and adjust the distance by tone. Hold one fork about an inch from your left ear and one an inch from to the right ear. This creates a long sustained pitch. This works well with the 128 Otto. The 64 and 32 Otto may also be used in this manner. When tapping the 64 Otto and 32 Otto, gently tap the body (the weighted portion) of the tuning fork on your palm. This will set the weights in motion and create a pure tone. The 32 Otto is especially effective for stimulating nerves on the skin and hair. Tap it by the body as described and than lightly touch your skin or hair with the edge of the tuning fork body. You will fell it stimulate, vibrate, and "tug" at your skin and hair. You can also tap the fork and move it very slowly across an area just above your skin without touching.

The set of 3 includes a free activator and velvet storage pouch.

Your brain has a natural ability to shift states — from anxious to calm, foggy to focused, wired to rested. The DAVID Delight makes that shift effortless.

Using Audio-Visual Entrainment (AVE) — a clinically researched technology combining pulsed light and rhythmic sound — the Delight gently guides your brainwaves into the state you need most. Whether you want to energize your morning, sharpen your thinking, settle anxious thoughts, or drift into deep sleep, there's a session designed for that. No pills. No screens. Just science-backed light and sound therapy in the palm of your hand.

Key Benefits

•       Reduce stress and quiet a racing mind

•       Fall asleep faster and sleep more deeply

•       Boost focus, memory, and mental clarity

•       Elevate mood and ease anxiety

•       Increase daily energy — without caffeine

•       Support overall brain health through increased cerebral blood flow and natural neurotransmitter production

Backed by research in: Seasonal Affective Disorder, insomnia, stress reduction, cognitive performance in students and seniors, mood regulation, and balance improvement.

What Is Audio-Visual Entrainment?

Audio-Visual Entrainment (AVE) uses precisely timed pulses of light and sound to "entrain" your brainwaves — guiding them toward a target frequency associated with a specific mental state.

10 Preset Sessions

Two sessions per category, so you can choose by depth, duration, or need.

Each category also includes a Sound Sync session that transforms your own music into a personalized light show.

Technology & Features

Tru-Vu Omniscreen Eyeset Glasses

The patented Tru-Vu Omniscreen design uses 8 blue-tinted white LEDs mounted over a silver reflector behind a translucent screen — dispersing light evenly and safely across both visual fields. Uniquely, it can stimulate each hemisphere of the brain at a different frequency simultaneously, enabling independent left-brain/right-brain entrainment for superior mood and cognitive results.

Three Audio Entrainment Modes

•       Isochronic Pulsed Tones — evenly spaced, equal-pitch pulses for maximum entrainment effectiveness

•       Monaural Beats — smoother, gentler pulses ideal for those sensitive to sharp tones

•       Binaural Beats — two pure tones (one per ear) create a perceived beat for deep brainwave guidance

Heart Rate Variability (HRV) Paced Breathing

Every session begins with guided HRV breathing — a clinically validated technique for calming the autonomic nervous system. The Delight paces your inhale and exhale cycles through audible heartbeat cues, helping to settle both sympathetic (fight-or-flight) and parasympathetic stress responses. You breathe in sync with the device, supporting deeper relaxation and faster session onset.

Proprietary Randomization Process

The Delight's randomization technology enhances dissociation — your brain's ability to "let go" and track the entrainment stimulus — resulting in more effective and consistent brainwave guidance session after session.

Soft-Off Fade Technology

Sessions end with a gradual dimming of lights and tones, preventing startle response (somatic shock) and preserving the calming benefits even after the session completes.

User-Friendly Design

•       Night-vue illuminated buttons — visible in the dark for bedtime use

•       Raised tactile power, intensity, and volume buttons — easy to adjust without opening your eyes

•       Battery power indicator — glance-and-go readiness check

•       9-volt battery powered — extended life with new eyeset technology
