The unique patented Tru-Vu Ominiscreen Eyesets have been carefully designed to provide you with the most effective and safe light and sound experience. These eyesets use eight blue-tinted white, wide andle LEDs mounted over a silver reflector behind a translucent screen. This disperses the light evenly and protects the LEDs. These LEDs are extremely efficient and last for over 100,000 hours. The maximum intensity of the lights in the eyesets is about 800 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. Not only are the Omniscreen Eyesets comfortable, but they are also built to last! They are made from sturdy, high quality sunglasses. The LEDs are protected and securely fastened behind the screen layer. The cord is also detachable from the eyeset, reducing the risk of damage to the cord. Now you can have six extra colors in one eyeset! In addition to the standard white, you can now experience blue, cyan, green, yellow, red, and magenta. You can also select separate colors for each visual field and random color selection.
