An optical device is disclosed. The optical device may generate light for projection into a user's eye. The optical device may have a switch connected to an eyecup. When the eyecup is pressed against the user's face, the switch may be actuated, signaling the optical device to generate light for projection into a user's eye. When the eyecup is not pressed against the user's face, the switch may be unactuated, signaling the optical device to cease to generate light for projection into a user's eye. Various electronics of the optical device may remain active, for example, a controller may continue to generate an image for representation by the generated light, but the optical device may refrain from generating the light, such as by a display. In this manner, inadvertent light leakage may be ameliorated, and power consumption by the optical device lessened when the eyecup is not depressed. |
