If you have a tendency towards seizures or auditory disorders, DO NOT listen to Hemi-Sync without first consulting your physician. The D.A.V.I.D Paradise Mind Machines D.A.VI.D, stands for Digital Audio Visual Integration Device. All D.AV.I.D. units feature Omniscreen goggles. They use white lights instead of red, green or amber LEDs.
Many people distinctly prefer white lights, which are fuller spectrum.
This also allows for open- eyed use. You can select the tint of light by inserting a colored filter, allowing for a color-therapy type effect. Units are supplied with blue, violet and yellow filters. They have complete, professional manuals and documentation. The keypad on all Paradise models allows for easier control and access with eyes closed or during a session.
