A tracking and display system for an eye of a person is incorporated into eyewear having at least one lens and being positionable in front of the eye or eyes with attachment hardware. A circuit with a power source is fixed with the eyewear and includes at least one multispectral LED adapted to project light towards the eye and at least one multispectral light detector adapted to receive light reflected from the eye. As such, movement, anatomy and physiology of the eye are determined according to an organized pattern of projected light reflected and received by the at least one detector. To display an image, light from the at least one multispectral LED is conveyed by at least one optical fiber to an eye-facing surface of a lens of the eyewear and then onto the retina of the persons eye to form a visible heads-up display image.
