JOINT DETERMINATION OF ACCOMMODATION AND VERGENCE

摘要

The present invention relates to methods (210) and apparatuses (110) for joint determination of accommodation and vergence of at least one eye (112, 112') of a user, for determining an accommodation of at least one eye (112, 112') of a user, for ascertaining values for checking myopia of at least one eye (112, 112') of the user and for producing a spectacle lens for the user, apparatuses for data processing and associated computer programs, computer-readable data media, data medium signals and computer-readable media. The method (210) for joint determination of accommodation and vergence of at least one eye (112, 112') of a user comprises the following steps: a) presenting at least one sign at at least one first distance (166) in front of at least one eye (112, 112') of a user for stimulating the accommodation of the at least one eye (112, 112'); b) capturing an eye movement of the at least one eye (112, 112'); and c) ascertaining a refraction of the at least one eye (112, 112') with the accommodation of the at least one eye (112, 112') at the at least one first distance (166); and d) joint determination of accommodation and vergence of the at least one eye (112, 112') by o ascertaining a change in the refraction of the at least one eye (112, 112') with the accommodation of the at least one eye (112, 112') at the at least one first distance (166) in relation to the accommodation of the at least one eye (112, 112') at a second distance (160); and o ascertaining the vergence of the at least one eye (112, 112') from the eye movement of the at least one eye (112, 112') with the accommodation of the at least one eye (112, 112') at the at least one first distance (166). Consequently, the present invention can be used, in particular, for checking myopia of the eyes (112, 112') of the user, in particular as a prediction value (226) for a development of refractive errors of the user.
