Abstract: The present disclosure describes tinting techniques in a lens stack assembly for a wearable head mounted display (WHMD). The lens stack assembly includes a waveguide disposed between two lenses, where the two lenses include tints to selectively reduce the amount of ambient light transmitted to the user while not reducing the amount of the display light in the WHMD. In addition, the tinting techniques described herein reduce or eliminate the generation of ghost images resulting from the reflection of outcoupled light from the waveguide away from the user back toward the user.

Abstract: A system includes a head-mounted display (HMD) device configured to project digital images to a user's eye and a viewing device.

Abstract: Systems, devices, and assemblies for implementing multi-focal lens portions in wearable heads-up displays are described. Multi-focal lens portions may include at least two regions having different optical power, and at least one transition region between regions having different optical power. If display light is directed through a transition region, aberrations or distortion may be visible in the display presented to the user. The present systems, devices, and assemblies address this issue through shaping, positioning, and orienting of regions of a multi-focal lens portion, through positioning, orientation, and aiming of display optics, and/or through arrangements of lens assemblies which prevent display light from travelling through a multi-focal lens portion.
