Aspects of the present disclosure relate to optical systems with ergonomic presentation of content for use in head-worn computing systems. A method for controlling a head-worn computer when viewing virtual images, including image content, that encourages an ergonomic head position to reduce neck pain, includes determining an angle of the head-worn computer relative to horizontal, determining an angle of a line of sight to the center of the virtual image as presented to a user's eye, determining a deviation between the determined angle of the line of sight and a predetermined ergonomic angle, and shifting the image content of the virtual image vertically as displayed to the user's eye so that a portion of the image content is not viewable, wherein the amount of shifting is in reverse correspondence to the magnitude of the determined deviation.

An imaging system includes a light source configured to generate a light beam. The system also includes first and second light guiding optical elements having respective first and second entry portions, and configured to propagate at least respective first and second portions of the light beam by total internal reflection. The system further includes a light distributor having a light distributor entry portion, a first exit portion, and a second exit portion. The light distributor is configured to direct the first and second portions of the light beam toward the first and second entry portions, respectively. The light distributor entry portion and the first exit portion are aligned along a first axis. The light distributor entry portion and the second exit portion are aligned along a second axis different from the first axis.

Near-infrared pulses are emitted from a pulsed light source. A scanner directs the near-infrared pulses as scanned light. An optical element directs the scanned light into the eye. The scanned light is scanned in two dimensions to form an image on the eye. Photon-pairs of the near-infrared pulses deliver a photon energy that is perceived as visible light.
