1. A computer-implemented method for operating an optometry device, the method comprising the following steps:
generating a first data set, the first data set containing information about a distance of a user of the optometry device to at least one object included in a scene, wherein the first data set is generated by using a LiDAR sensor, the LiDAR sensor being configured to measure the distance of the user of the optometry device to the at least one object by evaluating the scene represented by the first data set;
generating a second data set by recording an image of the scene by a camera, wherein the first data set and the second data set both include a same scene;
identifying, by a control unit, the at least one object by evaluating the scene represented by the second data set;
generating a third data set by an eye-tracking sensor, the third data set including gaze information of the user of the optometry device;
predicting a next gaze of the user based on the third data set; and
tuning a tunable lens of the optometry device based on the predicted next gaze of the user and on the distance to the identified object included in the first data set.
