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.
