This device consists of patient eye goggles ("ISEN-Goggles"). They have an adjustable, elastic headband, an LCD display, two green LED lights to provide optional focal points, eight infrared LED lights to provide illumination for the internal cameras, an internal SD-type memory, and buttons to operate the device's function. There is also a micro-USS port to facilitate transfer of data captured and stored in the device's SD-type memory. The patient eye goggles are an opaque, facially worn device fitted with two small video cameras, and two wavelengths of light emitting diodes (LEDs). One set of lights provides illumination for the cameras. The other allows the user to provide a focus point for the patient, if this is desired. These signals are processed by the image processor that allows for near-simultaneous viewing of the video images from both eyes on the attached LCD screen. (View less)
