Abstract: A method for simulating an ophthalmic lens on an eye of a subject viewing a virtual scene using a light field display including a light field window. The method includes calculating a virtual ray between a point of the virtual scene and a point of an eye pupil plane, the virtual ray passing through a virtual lens and being defined on the basis of a model providing a deviation angle of the virtual ray through the virtual lens, repeating the calculating for a plurality of virtual rays passing through the virtual lens and joining couples of one point of the virtual scene and another point of the eye pupil plane, determining a light field representing a modified virtual scene, and generating the light field representing the modified virtual scene on the light field window towards the eye of the subject.

Abstract: An optical device including a lens and a control member configured such that motion of the control member produces a change in the optical power provided along an optical axis of the lens. The optical device further includes a framework, a motor and a driving member. The motor includes an output shaft rotatively coupled to said driving member. The motor and the control member are mounted in the framework such that the driving member and the control member mechanically cooperate. The driving member is rotatably mounted in the framework. The optical device comprises biasing means for maintaining the driving member in a predetermined axial position along the output shaft axis and relative to the framework. This optical device can be used in an optometric equipment.
