Abstract

See full text

Device and method for determining an objective eye refraction parameter of a subject depending on a plurality of gaze directions, the device includes elements for ophthalmologically measuring an objective eye refraction parameter of a subject, and elements of visual stimulation of variable proximity and intended to stimulate the visual accommodation of the subject for first and second proximity values. The device includes opto-mechanical alignment elements for carrying out a first optical alignment of the optical axis of measurement on an eye axis in a first measuring position corresponding to a first angle of lowered viewing associated with a first proximity value to take a first measurement of an objective eye refraction parameter of the subject, and a second alignment of the optical axis of measurement on the eye axis in another measuring position corresponding to another angle of lowered viewing associated with another proximity value to take a second measurement.
