Abstract
An augmented-reality system has canted waveguides. The waveguides are canted at a wrap angle and/or a tilt angle. Input couplers to the waveguides are designed differently because of the different cant angles. Having canted waveguides allows waveguides to be formed in glasses and/or sunglass that have a base curvature.
