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.
