Zusammenfassung:An optical element may include two or more zones to perform functions in a head-mounted display (HMD) device. An optical component may include a first optical zone characterized by a first sag profile to correct a refractive error of an eye of a user and a second optical zone characterized by a second sag profile to redirect a path of an illumination light beam. A transition zone located between the first optical zone and the second optical zone may provide a smooth transition between the first optical zone and the second optical zone.
