The head mounted digital viewing system includes a sensor system, positionable substantially directly in front of the eyes of the user. The sensor system provides sensor video data. An image processing system is configured to receive the sensor video data. The image processing system modifies the sensor video data and provides display video data. A display system is positionable substantially in front of the eyes of the user. The display system is configured to receive the display video data and provide a display image to at least one eye of the user. The display system is positionable between the sensor system and at least one eye of the user. The line of sight of the sensor system and the display system are substantially aligned with the line of sight of at least one eye of the user. The sensor system and the display system are mechanically separate from each other and mechanically aligned with each other.
