Abstract
A polarization mechanism for a head-mounted device includes a linear polarization film and a waveplate film configured to polarize ambient light before it is guided to the eye of a user by a waveguide. The waveplate film is further configured to receive a reflection of the polarized ambient light off the waveguide and polarize the reflection in a circular direction such that the reflection is polarized in a first linear direction. The linear polarization film then receives the reflection polarized in the first linear direction from the waveplate film and polarizes the reflection in a second linear direction perpendicular to the first linear direction.
